Quality perforator. Model with perfect power

Sometimes in the process of repair and construction work, it becomes necessary to make a hole very urgently different size in concrete or some other very hard material. How can this be done without wasting too much time and effort?

So, in order to quickly make a hole in concrete, it is necessary to use special punchers, which simultaneously performs well as an electric drill and a jackhammer.

To date, this type of instrument a large number of and there is plenty to choose from. At the same time, too much choice often leads to significant difficulties, especially if a person has not previously encountered such a power tool.

You can find out which hammer drill to buy for your home, and what nuances you need to take into account during the purchase, both on your own and with the help of specialists who can suggest exactly those options that are best suited in your individual case.

Perforators: types and their features

Today, depending on the functions that the tool performs, you can find three different types:

1. with one mode;
2. with two working modes;
3. with three modes.

Single-mode rotary hammers are among the professional ones that can perform only a few functions. Such models have an incredibly simple design, but it is better not to take such a puncher for home. The single mode tool has a special hammer drilling function. The same models, where there is only an impact mode, are commonly called jackhammers.

A little more often you can find two-mode instrument models. In addition to impact drilling, such models have an additional mode where you can set drilling or chiselling separately.

In three-mode punchers, you can find all the functions that were listed a little higher. The drilling mode is usually used when you need to work with a metal or wooden surface. Drilling simultaneously with impact is usually used to work with bricks, concrete. Impact mode, in turn, allows you to remove tiles from any surface. Before purchasing a hammer drill, it is very important to pay attention to the functionality of the tool, because at home you often need to use all three possible modes.

In addition, perforators can be divided into types directly according to the mechanism of their work. In this case, the tools can be electromagnetic or pneumatic, gasoline, battery, and so on. In my own way appearance the tool can remind the user of a gun that has a drill.

The principle of operation and the device of the perforator

The power tool has a rather complex design, which includes an electronic or brush reverse, a speed controller, a friction clutch, an electronic immobilizer, vibration protection, special indicators, a system that allows you to change cartridges in a puncher as simply and quickly as possible. It is worth noting that the designs of different manufacturers may differ to some extent from each other, but the mechanism of operation for all tools is the same.

The principle of operation of the perforator was based on a special percussion mechanism, which can be pneumatic or electromagnetic. The electromagnetic mechanism works due to the fact that electromagnetic coils are installed in it. With their help, there is a movement of the core, which has a reciprocating direction. In turn, the core transmits blows directly to the end of the drill. The pneumatic mechanism is performed by moving a piston in a small cylinder. Most often, this hammer drill is bought for the home, as it is more convenient and suitable for homework.

In some cases, an additional drilling nozzle can be used with the tool corner type, which is used for areas that are difficult to reach. In addition, there may be a drill angle controller, a system that eliminates dust, drill bits, and even a chisel attachment.

The main technical characteristics of the perforator

The main characteristics that you should pay attention to are the power of the tool and the force of impact. What is the best hammer drill for homework? The answer is incredibly simple. The one with the highest parameters. It is worth paying attention to one very interesting fact. The impact force will not always correspond to the power and this is explained by the fact that different instruments have different designs.

To date, you can find tools that have two different types of cartridges. They can be regular or quick-release. The second version of the perforator is considered to be much better and is bought not only for the home, but also professional work. Such a cartridge provides the opportunity to change the drill, while easily pressing it. The big advantage is that there is no need to use a special key.

Another characteristic that you need to pay attention to when choosing a rotary hammer is the weight of the tool. You can find light (up to 3 kg.), Medium (from 3 to 5 kg.) Or heavy units (more than 5 kg.). Light models are initially equipped with an SDS-plus cartridge, which allows the use of cartridges up to 26 mm. Heavy models have a slightly different SDS-max cartridge, which makes it possible to work with drills up to 60 mm. If we talk about medium models, then, depending on the model range, both one and the second type of cartridge can be installed on the tool.

Exactly the same as most of other electric tools, perforators can work both on mains power supply and with a battery. An important point there is that battery type models have more high cost than standard units.

Experts also recommend not to forget about the presence of electronic speed control, which is quite important for both professional hammer drill models and those that you choose for home work. This option will make your work easier and will allow you to choose the correct rotation speed depending on the size of the drill, as well as on the load on the tool. It is worth noting that speed adjustment allows you to increase the life of the tool several times, and all work is done much better. Today, such an important option is already installed in most of all models.

When it comes to how to choose the right hammer drill for your home, you can stop at the middle type of models, the functions of which will be more than sufficient. It is worth noting that heavy tools in almost all cases are among the professional ones.

Modern models have not only the standard features that are in all rotary hammers, but also additional options that are aimed at greatly facilitating the work with the tool. Very often you can find such an option as “soft descent”, which saves the unit from strong vibrations after work is completed and turned off. If a special safety clutch is installed, it will protect the engine from overheating or from sudden breakdown.

In more expensive perforator models, an additional special system which prevents the instrument from vibrating. At the same time, two-speed gearboxes and a fully insulated solid metal housing can be present. Such models are aimed at doing quality work and at the same time creating a minimum amount of noise.

When you intend to buy a hammer drill at home, you need to understand that you are unlikely to need an incredibly powerful and very heavy tool. Quite often, medium-weight tools are bought for homework. Great popularity in Lately uses not very expensive, but at the same time high-quality brand Makita. Of course, you can choose other models that have similar technical characteristics. To a greater extent, the choice of tool will depend on what kind of work you are going to do with it in the future.

How is an impact drill different from a hammer drill, is there a difference?

A perforator is a special drilling machine that makes longitudinal and axial movements and rotating. As numerous practice shows, it is often confused with another tool - a percussion drill. Is there a difference between these two building-type devices?

There are differences, and they are in some subtleties of how exactly the percussion function is performed. For a drill, this function is performed in mechanical mode, and for a hammer drill, in turn, in pneumatic mode. Due to this, this tool can easily make a hole in very hard material: brick, concrete, stones, and so on. Working with it is quite simple and fast, you do not need to make a lot of physical effort, unlike impact drill.

In addition, they have many more functions, they are quite massive and are large in comparison with a drill. Accordingly, the level of performance and service life is much higher and longer, which characterizes itself as a more reliable tool.

What is the difference between an impact drill and a hammer drill video

Which hammer drill is better to buy for home use is a rather difficult question, because today there are many different models. If you can’t decide on your own, then use the advice of experts who will tell you which tool is best for your individual case.

The older generation, who never held an electric hammer drill, struggled with stubborn concrete for decades. Drill a hole in it, even using a hard drill bit, very difficult.

Concrete well withstands the pressure accompanied by the rotation of the drill. But it cannot resist the effects of high-frequency shock loads for a long time.

Today, the electric rotary hammer has become one of the most popular tools for working with hard building materials(stone, brick, concrete). With it, you can drill holes, dismantle monolithic floors, dismantle walls and ceilings, make grooves (strobes) for laying communications.

During apartment renovation and in a new building, you cannot do without this tool. In order to choose a hammer drill for homework, you need to have a good idea of ​​its performance characteristics and varieties. It is on this topic that we will talk.

What are perforators?

First of all, let's draw a clear line between this tool and an impact drill. For beginners, it is not always obvious. The impact drill uses an electromechanical impact pulse that occurs when the drive pinion tooth crown disengages from another tooth crown. Its strength is small, so it is not standardized in joules (a unit of impact force).

The perforator uses an electro-pneumatic impulse. This is where the force of air compressed by the piston comes into play. Its intensity is very high. Due to the absence of direct mechanical contact between the striker and the drive mechanism, tool wear is significantly reduced and its life is increased.

Electro-pneumatic impact in perforators is implemented through two different mechanisms:

• Oscillating or "drunk" bearing;
• Crank group.

The first type of drive mechanism consists of an oscillating bearing (1), a piston (2), a ram (3), a striker (4) and an engine drive gear (5).

He works in the following way: The bearing translates the rotary motion of the electric motor into the forward stroke of the piston, which compresses the air in the chamber. The air pushes the ram, which hits the striker. This principle of operation is used in light and medium rotary hammers. The engine in such a tool is most often placed in a horizontal position.

The crank shock group is used in powerful rotary hammers with a vertical arrangement of the electric motor. Here, a crank with a connecting rod pushes a piston that compresses the air in the cylinder. Its energy is transferred to the ram, which hits the drummer with great force and amplitude.

The electric motor in such a shock system is placed vertically.

How to choose the right perforator?

For this, there are two main guidelines: the power of the electric motor and the energy (strength) of impact. The first indicator determines the working capabilities of the tool and affects its weight.

Of course, a heavy puncher will cope with any material faster and better, but it is more difficult to work with it than with a "lightweight". Therefore, when deciding which hammer drill is better to buy for the home, you need to focus on the types of work that you have to do most often.

On the basis of the power of the electric motor, there are three categories of rotary hammers:

• Lightweight (power 500-800 W with a weight of 1.8 to 3.0 kg);
• Medium (power 800-1200 W and weight from 3.2 to 6 kg);
• Heavy (power from 1200 to 1600 W with a weight of 6 to 11 kg).

Lightweight electric hammer drill can drill holes in concrete surface diameter up to 26 mm. He will cope with the breakdown of the mortar screed, make strobe channels in the wall and on the floor. It is this type of tool that is most often bought for home use.

Medium rotary hammers are designed for drilling holes up to 32 mm in diameter in hard materials. They are actively used by repair teams and builders.

Heavy punchers are professional tools. They are designed for dismantling and drilling of large diameter holes (50-60 mm). For household needs they don't fit.

Having estimated the engine power in the selected tool, you must definitely look at the energy (strength) of its impact. It is measured in joules and tells the buyer what can be done with such a puncher. For small repair work enough impact force in the range of 1.5-3 J. With this tool, you can easily drill brick and cinder block, but for constant contact with concrete, it is better to purchase an “assistant”, whose impact energy is from 4 to 6 J.

Heavy professional hammers are capable of destroying material with a force of up to 20.0 Joules. They can not only drill in concrete enough big hole, but also fully used as an electric jackhammer.

When choosing an electric hammer, you should also pay attention to the frequency of impact and the speed of rotation of the cartridge. The higher these figures, the more even holes you will be able to drill.

With power, everything is clear. What about "twists"?

What buyers usually refer to as "bells and whistles" are more properly called useful additions that make work easier and better.

These include:

• Anti-vibration system.
• Chuck rotation speed adjustment.
• Safety clutch (protects the electric motor from overheating when jammed).
• Two-speed gearbox (allows you to work at different speeds).
• Reverse rotation.
• Constant electronics (maintains speed stability under loads of different intensity).
• Motor brush wear indicator.
• Electronic immobilizer (turns off the tool in case of power surges and short circuits).

A few words should be said about the most common types of keyless chucks.. There are two of them: SDS + and SDS MAX. Light perforators are completed first. SDS MAX is designed for medium and heavy class tools.

The main difference between these types of cartridges is the diameter of the tail of the drill. In SDS+ it is 10 mm, and in SDS max is 18 mm. The number of modes of operation of the tool depends on the type of cartridge. There are three of them for SDS+: normal drilling, hammer drilling and clean hammer.

A rotary hammer equipped with an SDS MAX chuck does not have a drilling mode. This is understandable, since it is inconvenient to drill wood and metal with such a powerful and heavy tool.

Other subtleties of choice

Speaking about the horizontal and vertical arrangement of the electric motor, users give several arguments:

• A tool with a horizontal (longitudinal) placement of the engine is more convenient to use, since its mass is better balanced.
• The advantages of a vertical layout are compactness, lower engine heating, best protection from dust, higher power and resource.

Knowing these arguments, you will be able to more accurately and consciously choose the right tool.

Increasing the capacity of batteries and reducing their size allowed designers to create a cordless puncher. This tool does not strike the imagination with the impact force (maximum 3.0 J), but attracts buyers with autonomy in operation and compact size.

Popular manufacturers and estimated prices

When choosing an electric hammer for homework, it is difficult for a beginner to understand the abundance of brands and promotional offers.

For detailed description price and consumer characteristics of all categories of punchers would require a separate article. Therefore, we will focus only on the most popular brands and prices for household instruments (power up to 900 watts, impact energy up to 3 J).

Anyone who is looking for a cheap punch should pay attention to the budget segment. Here the Russian trademarks Zubr, Interskol and Energomash "rule the show". In most cases, you will have to pay no more than 6,000 rubles for the tool of these companies. Its reliability and endurance cannot be called ideal, but it most often works out the money spent.

Perforators sold under the “German-sounding” brands Bort (Board), Einhell (Einhell), Hammer (Hammer) and Sturm (Sturm) can also be included in the same price group. Of the four listed, the last three brands have good quality. But about the Bort tool, you can find a lot of negative reviews.

A higher level of our rating is punchers from Bosch (Bosch), Makita (Makita), Hitachi (Hitachi), Metabo (Metabo), AEG (AEG), Dewalt (Dewalt). Their prices range from 6,000 to 13,000 rubles, and in most cases the quality completely satisfies home craftsmen.

Of the tools in a higher price category, but, nevertheless, gaining popularity not only among professionals, but also among home craftsmen, one can distinguish Hilti brand punchers (Hilti). The cost of the cheapest network model is about 9000 rubles, more expensive 15-18 thousand rubles.

The company also offers a number of battery models costing from 30 thousand rubles with a complete set.

Analysis - reasoning on the topic "what is better to choose Bosch or Makita?"

When the price and quality of perforators are approximately the same, the buyer wants to find a decisive argument in favor of a particular brand. Most often, disputes are heard around the German brand Bosch and the Japanese Makita. Since the Japanese position their tool as a professional tool, only the “blue” Bosch, a line of heavy-duty rotary hammers, can compete with it on an equal footing.

Discussing which is better Bosch or Makita, we note that the German company is more actively introducing technological innovations into its tool that improve comfort and quality of work. In addition, according to service statistics, Bosch requires less repair, and the cost of its restoration is lower than that of Makita.

The positive qualities of the products of the Japanese company can be called high reliability and endurance, small weight and dimensions. Speaking about the shortcomings of the Japanese brand, some users call the not very convenient design of some models.

This article is a continuation of the cycle, now all our attention is on perforators, good and not so good. During repair and construction, a perforator is indispensable. This is the tool that makes life easier for us most of all, it is on it that the heaviest loads fall. All tool companies also make punchers - the offer is off the charts. It is very easy to make a mistake with the choice of a reliable device suitable for specific conditions, but such a miracle of technology is not cheap.

Age builders say that earlier holes in concrete, brick and stone were made using a jumper. Apparently also a German invention (German: Schlagbohrer; schlagen - to beat, and vohrer - drill). This is such an instruction made of durable metal pipe with notches, on which, with all the strength, you need to hit with a hammer and gradually turn it so that it does not jam. Next, a planed wooden cork is used, a nail is hammered into it or a screw is screwed in.

Simultaneously with the fall of the Iron Curtain, the bolt was replaced first by foreign-made percussion drills, then by the first hammer drills. The post-Soviet space again experienced a technological revolution. Very opportunely arrived in time and previously unknown fixing systems, dowels "quick installation", dowel-wedge TDN, expansion anchors. Finishers got the opportunity to quickly and reliably fasten the cladding to the supporting structures, to make through holes for passage and fixation engineering communications. The era of renovations has begun.

When did my conscious labor activity, perforators were already hard at work on the construction sites of the country, and I saw the bolt only on TV. My first "perf" did not live long, about two or three months. I don’t remember its name anymore, but I can only say that it was the cheapest Chinese barrel, which my partner and I bought together. True, he managed to pay for himself. From morning to evening, they drilled them under dowels, drilled metal, hollowed out strobes, kneaded tile adhesive, demolished partitions ... Surely, the branded apparatus would not have endured such an attitude towards itself. It was a very valuable experience, we clearly decided how to competently equip the team with percussion and drilling power tools, some practical skills and rules regarding the operation of serious equipment were developed. Once again, we confirmed the well-worn rule for ourselves: “The universal is the enemy of the good.” We decided that as we develop, we will need a separate electric jackhammer, a separate mixer, a separate lightweight and compact rotary hammer. It is light and compact, not heavy duty and fancy. It's just that most of all (90% of the working time) we work with a 6 mm drill for mounting all kinds of frames, often in the ceiling area, with our hands raised above our heads. Much less often it is necessary to make holes about 20 mm in diameter in order to stretch an electrical cable in a corrugated or plastic pipe heating/water supply. Crowns for socket boxes somehow did not take root with us. Larger diameters at our facilities are drilled only by air conditioner installers, but this topic is not ours. There was reconnaissance in force. Companies participated in the casting: Einhell, Makita, and, of course, BOSCH.

Einhell BBH 920

No matter how hard we tried, the Einhell BBH 920 perforator practically repeated the fate of the firstborn, only it worked in difficult conditions for about a season, after which it stopped beating and was transferred to the category of mixers, since the repair was half the size of a new perforator.

Einhell BBH 920

Under the mixer, his anchor burned out safely. They say it is wound with aluminum, I can’t confirm - I didn’t understand it. Impressions were mixed. A horizontally mounted engine is already something, there are clearly more amenities than with a vertical one. There is already a soft start and anti-jamming, chiseling, hammer drilling and hammerless drilling. The gearbox has an aluminum casing, the body itself is durable, made of fairly elastic plastic. I don’t know what is the reason, but even using the punch for its intended purpose, quite often I had to change the brushes. Cord insulation is brittle, weak plug. The ergonomics of the product is quite tolerable, one might say, traditional. The button and switches have worked flawlessly for the entire service life. It feels like the frequency and impact force (2.5 J) does not correspond to the declared ones, the tool drills slowly and heats up quickly. Apparently, the developers did not manage to realize the impressive engine power (920 W) in performance. 3.2 kg of weight also does its dirty work, hands get pretty tired by the end of the day.

Note that in addition to the three-mode apparatus, there is a good suitcase, equipped with decent drills, an additional handle, a pike and a chisel.

We can say that the model could successfully cope with its tasks, being in the arsenal home master. But on this moment this hammer drill will not withstand competition even with household samples of European brands, neither in terms of quality, nor in terms of real tactical and technical indicators. Its price has recently grown significantly and is approaching $ 90.

Makita HR2410

Next was the Makita HR2410 - a classic, if not legendary, representative of light rotary hammers. You can really enjoy working with such a thing. Not only does the device weigh only 2.3 kg (compared to 3.2 kg from Einhell), it is also perfectly balanced, has a neat “slick” body.

Makita HR2410

The handle is comfortable both with a “pistol” grip and with an emphasis along the drilling axis, which has a positive effect when working overhead. The mode switch is located unusually - from below (the sides are smooth - one less hook).

special attention The electronic switch deserves just a huge size, its key has a large stroke, which makes it possible to change the speed very smoothly. The significance of this chip can be felt during drilling in metal or when the drill exits the workpiece. The model is rightfully considered professional, there is a safety clutch, electronic speed control, reverse. I personally lack the chiselling mode, it is very convenient to clean the masonry with a perf, knock down small influxes of concrete in the corners. Sometimes I use this option when I need to dismantle a profile, let's say it was erroneously mounted (I push the dowel through the metal with a drill, and the UD or UV is released). Impact force (2 J) and engine power (680 W) are enough for the basic needs of a finisher.

Many of my colleagues will not fail to notice that this model is the last century. That's how it is, but the old HR2410 has been working properly for ten years, and it seems to have cost a little more than $200. Statisticians say that at one time it was the best-selling hammer drill in the world - it seems not by chance. I'm probably old fashioned, but if this Makita was being made now, I would honestly recommend it to all my friends. Of the new, relatively inexpensive models, I would choose between HR2610 and HR2470. I could not ignore the compact, ultra-light HR1830, but this, of course, is not for everybody.

BOSCH GBH 2-24 DSR

Everyone knows the saying: “You can’t break through a wall with your finger - you need a Bosch puncher.” I have. Three! BOSCH GBH 2-24 DSR has become our main strike force. It has been working flawlessly for many years, sometimes just not turning off.

BOSCH GBH 2-24 DSR

It was not necessary to repair, for all the time (probably more than ten years) the brushes and one worn boot changed once. The machine is quite compact, weighing only 2.4 kg, but it produces as much as 2.4 J of impact energy. The engine is not very powerful - 680 W, but this is enough to drill holes in concrete with a diameter of up to 24 mm, as, in fact, indicated in the passport. My most used 6x160 drills go into the wall effortlessly. The model has necessary set options, characteristic professional puncher. Among them are electronic speed control, a safety clutch, which really works when the drill is jammed. I am glad that there are three modes, which is a little lacking in the Makita HR2410. Their switch is large, but clear and informative - you need to try to put it in an intermediate position and not notice the absence of a characteristic click. It has its own button that protects against accidental translation.

The flat chisel can be fixed at almost any angle (36 positions). The reverse and smooth sensitive button allows, if necessary, to use it as a heavy-duty screwdriver for long self-tapping screws or serious drilling. All you have to do is insert the adapter chuck. A button that fixes the “start” key in the pressed state helps to unload the hand during intensive work. It also makes it possible, if you are drilling in an uncomfortable position, to remove your fingers from the handle and slightly press on the tool along the drilling axis, this, by the way, is facilitated by a pronounced “visor” on the body. Another feature of the GBH 2-24 DSR is a really long power cord that usually reaches any outlet in the room.

Standing on the scaffold, you can not be afraid to step on the electric carrying block or open the connection at the most inopportune moment - it rests somewhere on the floor. For those who like to work with two hands, the manufacturer equipped the puncher with a handle that can be moved around in a circle, but it bothers me more. The set comes with a convenient spacious case made of solid plastic.

A real workhorse, never failed for many years of merciless exploitation. Great machine for professional use. GBH 2-24 DSR is really worth the money, and its price was about $250. BOSCH is constantly improving its line of light rotary hammers, and this model has already been discontinued. So, soon we will look for new heroes, there are plenty to choose from. I held a lot of more or less fresh boches in my hands, I really liked the GBH 2-20 D and GBH 2-24 DF.

BOSCH PBH 2000 RE

After good impressions from a household screwdriver, I decided to try a rotary hammer of the same BOSCH PBH 2000 RE series in practice. I will say right away that the result exceeded all expectations.

BOSCH PBH 2000 RE

I took it purely for quick assembly 6x40, 6x60. But with a maximum single impact energy of 1.5 J, the “baby” can easily cope with larger holes, up to the declared 20 mm. Almost as simple as the light blue professional counterparts. Could this be? In general, the ratio of motor power to an impact force of 550 W / 1.5-1.7 J in professional circles is considered ideal in terms of tool wear resistance, many manufacturers adhere to this proportion for ultra-light models. Its engine is only 550 watts, so some difficulties, of course, arise on viscous bases (for example, not completely dried concrete), but this is rather a rare exception to the rule. It feels very fast, I looked into the passport - indeed, the impact frequency is 5800 beats / min., And the nominal shaft speed is 2300 rpm.

For comparison, these figures for GBH 2-24 DSR are 4850 bpm. and 870 rpm. respectively. Now it's clear that the developers have relied on speed. In addition, the Germans proposed an interesting design of the percussion mechanism: they did not use a gearbox, but transferred the rotation of the engine directly to the pneumatic drive spindle, the striker was fired along a unique trajectory, the barrel was securely fixed with a 50 mm spindle neck. Such technological innovations and the use of very high quality parts made it possible to make the PBH 2000 RE a three-mode machine with a clean chiseling function (plus, you can fix a certain position of a flat chisel), which the competitors did not dare to do. There is a latch of the included button, it is recessed into the plastic of the handle and does not work from an accidental touch. Manufacturers do not talk about anti-jamming protection, but there is a feeling of operation of a sensitive overrunning clutch - probably this is secret information about another know-how. We have a reverse and a very sensitive button that provides electronic speed control, smooth acceleration from 0 to maximum. Therefore, we put a transition cartridge, and we work further like a screwdriver. The puncher is the lightest and most compact of all that I held in my hands. Its weight is only 2.2 kg, along with three meters of cord, the length is 32 cm.

The plastic of which the case is made is pleasant to the touch, obviously shockproof - checked. The recognizable triangular body design makes it even more durable and stable. And BOSCH PBH 2000 RE is incredibly beautiful.

This is a great hammer drill, even for the construction site. Positioning it as a tool for home use is rather conditional. The conclusion suggests itself that BOSCH is one of the few that made a budget line of tools “for the home workshop” and was forced to “strangle” the characteristics of the professional series a little for the assortment. But something special came out, for which many thanks to the developers. For three years we have been exploiting this baby at the facilities, and there have been no problems, even the brushes have not been changed. I think it can easily outlive several Chinese copies that are close in price. The cost of PBH 2000 RE in retail is only $110-120.

The reason for the longevity of my perforators, in many respects, I consider a careful attitude towards them and strict adherence to the manufacturer's recommendations. I also set some general rules for myself:

1. Use only high-quality branded accessories (lubricant, adapter cartridge, drills).
2. Perform regular cleaning and maintenance.
3. Don't forget to lubricate the SDS shank of the working tool.
4. Do not overload the puncher, give it time to cool down.
5. A long hole was drilled in several passes (pulling out the drill, you remove the waste).
6. Do not press on the perforator - the armature may overheat, the impact mechanism will wear out.
7. Don't work too long in the chiseling mode - spin the machine on a clean rotation for a couple of minutes (this simple operation provides both cooling and forced lubrication of the parts).
8. Do not bend the working tool relative to the axis of the hole - the cartridge breaks.
9. Check the condition of the anther and brushes.
10. At the slightest malfunction, bring it to the service, do not allow costly breakdowns.
11. Do not take Chinese, it is better to support a responsible German manufacturer (yes, I know, I know that everything is now assembled in China).

Turishchev Anton, rmnt.ru

One of the most indispensable things in the house is a perforator. This is especially true for those apartments where the walls are made of brick and concrete. It will be quite difficult to make holes in these materials with a conventional drill, even if the tool is equipped with an impact mechanism. But to dismantle separate part walls without a perforator will not work at all. That is why the modern consumer today is increasingly considering the rating of punchers, from which you can find out which model and with what characteristics it is better to give preference.

Rating by main characteristics: impact strength

The characteristic mentioned in the subtitle is also called impact energy and it is measured in Joules. It will depend on it to what depth with the help of a perforator you can immerse yourself in the material. If we are talking about a light household tool, then this value will vary from 1 to 2 J. It should be borne in mind that the insignificant impact energy will not allow holes to be punched properly. This is due to the fact that the puncher in this case will work according to the principle

Model with perfect impact force

If you still decide to purchase a tool with such an impact force, then it makes sense to consider the Kolner KRH model, which can operate in one of three modes, providing an impact energy of 2.2 J. You can work with this tool when drilling with impact, in drilling or chiseling mode. It provides for this equipment and the presence of a protective clutch, with which you can prevent the device from turning in your hands when the equipment is jammed. Non-through holes, accurate in size, can be drilled using a depth gauge.

Considering the rating of hammer drills for domestic use, you can pay attention to this model, because it has many advantages, including the ability to quickly change equipment thanks to the SDS-plus chuck. The manufacturer took care of the presence of a reverse, turning the bit and an additional handle with which the operator can hold the tool. As additional advantages, it is necessary to highlight the possibility of adjusting the rotational speed, as well as the presence of the “Start” key fixation functionality, this will ensure the possibility of continuous operation.

Model selection according to the drill attachment system

Having visited the store and read the rating, you will understand that the manufacturer can provide one of the existing systems for attaching the drill. This feature will affect the behavior of the unit during use on the reliability index. Thus, the SDS-plus system, which is available in the above model, is used in small rotary hammers, the weight of which does not exceed 4 kg. Such a device is capable of making holes with a diameter of up to 3 cm.

The device of this type is compact, so it is very convenient to use them in everyday life. In addition, for this type of fastening of the drill, you can additionally purchase equipment. On sale you can find devices with equipment of a rarer system - SDS-max, which is not always possible to find in small stores.

Choice by power

Rating perforators allows you to choose a model that will suit you in all respects. Thus, power is a fundamental factor that influences the decision of consumers. Even the highest quality home appliance has less power than any other drill. When punching holes, the type of energy will be much less than when drilling. The drill should not spin as fast as the drill in the case of a drill. To achieve a high rotational speed, a large amount of energy is needed. If you have light hammer drills in front of you, the power of which varies from 400 to 800 W, then they can be used for home repairs. By the way, they are the most popular.

Model with perfect power

As an example of such equipment, we can consider the KOLNER KRH 520 H model, the power of which is 520 W. The equipment is powered by a 220 V network, and the number of revolutions can reach 1000 in one minute. The operator will be able to use only one speed, and the impact force is 1.5 J.

The manufacturer provided for the presence of a reverse, and the number of strokes can reach 3900 per minute. Considering the rating, you can pay attention not only to power, but also to other characteristics, for example, the ability of the tool to make holes in different materials. In the case of this model, the maximum hole diameter in metal, wood and stone will be 13, 30 and 20 mm, respectively. The tool weighs only 2.7 kg and comes with a safety clutch for easy handling.

Rating by the number of operating modes

Rating the best punchers assumes the presence of models that have three modes of operation at once. However, on sale you can find tools with one or two modes. In the penultimate case, we are talking about a unit that is similar in functionality to a drill. With it, you can drill a metal or wooden surface. Hammers with two modes are capable of performing more species works. With their help, you can drill, as well as connect drilling with axial movement.

If you have a tool with three modes, then you can be sure that it has all the features of the types of work described above. With it, you can make strikes, eliminating the rotation of the equipment. In this case, the third mode will be performed in the form of a pure blow.

An example of a model with two modes

For example, the KRATON RHE-550-22 model has only two modes. The power of this equipment is 550 W, and in one minute the number of revolutions can reach 850. It will be possible to work with this tool only at one speed, while the impact force is 1.8 J. This tool weighs 2.3 kg. For domestic use, this mass is perfect. It is noteworthy that the equipment is supplied in a case, which is convenient for those users who often work outside the home.

Manufacturer's choice

Manufacturers of rotary hammers, whose rating you can find in the article, offer for sale different models that will meet certain requirements. In the store you can find models that differ in color. The hue will indicate whether the instrument belongs to the household or professional class.

Many consumers try to choose the most reliable hammer drill, the rating helps them with this. From it you can find out that the most popular brands today are:

• hitachi.
• MAKITA.
• STERN.
• Bosch.

If you are interested, then you should know that they are comfortable, reliable and lightweight. If you need to carry out a small repair in the office or at home, then these tools will perfectly be able to perform their tasks. The manufacturer most often supplies the equipment with a reverse handle, as well as an operating mode switch located at the back. The Makita HR2450 models are the most popular among consumers and by choosing one of them, you can use a power of no more than 700 W, as well as an impact force of 3 J. As for the engine speed, the tool will be able to produce 4500 units in one minute.

Features of Bosch rotary hammers

The best hammer drills for the home, the rating of which is presented in the article, are offered for sale by a German manufacturer Bosch. These units are manufactured according to modern technologies and are characterized by high quality, increased reliability and durability. Their electronics clearly work, but in practice, tools rarely fail.

Using the appropriate functionality, the operator will be able to quickly and accurately adjust the number of revolutions of the drill. If you saw Bosch rotary hammers in the store, then you should not choose the one that is blue, as it is designed for professional use. For the home, models painted in green are suitable. It is not worth talking about which options are better to prefer, since all of them have the proper quality.

Rating of Russian punchers

Russian perforators, the rating of which, perhaps, will allow you to make the right choice, are offered today at an affordable cost. For example, you can find the Interskol P-45 / 1000E model, for which you will have to pay 23,000 rubles. This equipment works in two modes, namely, like a perforator. Another equally well-known manufacturer from Russia is Caliber. If you are interested in the products of this company, then you can prefer the EP-800/26 model, which is suitable for domestic use and is quite cheap. You will have to pay for it only 4000 rubles. But in terms of functionality, this equipment is not inferior to more expensive models, because the operator with its help will be able to work at three speeds, using a maximum impact energy of 3.2 J. The power consumption of this device is 800 watts.

If you are interested in the rating of household punchers, then you can pay attention to one more Russian manufacturer- Energomash, which offers many models for sale. Among them you can find the PE-25500, for which you will have to pay 2900 rubles. The power consumption is 500 W, the maximum impact energy is 3.4 J. With this equipment, you can work in the mode of a screwdriver or drilling. Among the additional functionality, it should be noted: blocking the power button, reverse, additional handle, depth gauge.

Conclusion

The rating of rotary hammers will allow you not only to make the right choice, but also to determine the optimal characteristics. Among them, one should certainly highlight the power, which varies from 500 to 800 watts. For such equipment, the impact force should not exceed 2.2 J, but should not fall below 1.2 J. Experts do not recommend choosing tools that have less than 3 operating modes. Indeed, when carrying out repairs, you will need not only a simple rotation mode, but also rotation, which can be accompanied by blows. Sometimes there is a need to use the impact mode, which is not accompanied by rotation. Hammer drills, the reliability rating of which was presented above, should also be chosen by you according to the presence of a protective sleeve, which will eliminate the possibility of jamming the drill.

The perforator is an indispensable assistant in dismantling work. With it, you can perform drilling, chasing and destruction of solid structures, applying for this a minimum of physical effort. Although percussion equipment of this type is considered professional, it is often used in domestic settings. Modest in terms of performance, a model of such an apparatus will not be superfluous in household. How to choose a perforator for an ordinary user? Since the tool is not cheap, the approach must be responsible and comprehensive - key performance indicators, functionality, user reviews, etc. are taken into account.

Optimal type of perforator

At the first stage of selection, one should decide on the basic belonging of the instrument to one or another category according to the main classifications. In particular, the design and power supply system should be determined. As for the structural device, there are horizontal and vertical perforators for home. Which to choose? Models of the first type with a horizontal engine are more like drills. In essence, this is an electric drill, but supplemented with an impact function - a kind of jackhammer. This option is easy to handle and a good choice for a beginner, but it is unlikely to be able to perform complex operations for the destruction of concrete and brick structures in a large volume. The vertical configuration is distinguished by power and a more efficient cooling system - accordingly, the device will be able to work at high loads.

Now you can go to the power system. Network and battery models are fundamentally separated. As the reviews show, the first ones have a greater power reserve, while maintaining a compact body and lightness. The presence of a battery pack makes the design heavier and reduces maneuverability. Although, the addition of weight in the case of a perforator can also be a plus, since the stabilizing effect increases, which is important when hard work. How to choose a rotary hammer by type of battery? It is worth focusing on lithium-ion cells (Li-Ion). They have no self-discharge effect, small size have a high energy potential and are undemanding in maintenance. But, one should also take into account the capriciousness of the Li-Ion block when working at low temperatures and the price factor - rotary hammers with such power supply are 10-15% more expensive than other models.

Choice by technical specifications

The performance range varies depending on the model class. So, the initial level is represented by devices weighing 3-4 kg and with a power of 800 watts. The impact energy in this case is 1-2 J. It turns out a low-power device that is suitable, for example, for electrical wiring, but it is better to entrust serious work with chiselling and deep gating to more productive versions. How to choose a rotary hammer for medium-sized homework? The power potential in this case may also not exceed 1000 W, the main thing is the impact energy. It is desirable to carry out dismantling operations with chiselling with a tool with a force of 3 J or more. This is enough to perform overhaul with the creation of large-format holes and openings in the wall. But, as a household drilling machine, such a tool is no longer used.

Manufacturers also produce heavy punching equipment designed for domestic tasks. Models of this class are designed to form 40 mm holes and breaks stone walls. But in addition to power, it is worth noting the structural reliability and functionality of such rotary hammers. What is the best device to choose from this segment? To perform complex responsible tasks, it is better to purchase models with a power of at least 1200 watts. Accordingly, the impact energy will also be considerable - about 13 J. The influence of high loads on the electrical stuffing is also taken into account. It will be useful to provide for the presence of protective systems and fuses. However, additional options should be considered separately.

How to choose a perforator by functionality?

Continuing the topic of safety and protection of the tool itself, we can highlight the soft start system, overheating protection, fan cooling of the engine, etc. From the point of view of performance, the possibility of reverse (reverse) movement and changing the position of the bit will be significant. In particular, Bosh uses its own Vario-Lock mechanism to correct work equipment. As for the reverse, it can be useful in cases where the drill goes to the side or gets stuck in a rigid array with a rebar grip. But how to choose a rotary hammer if you plan to use different nozzles in addition to large-caliber shanks? It is advisable to give preference to SDS-max or SDS-plus keyless chucks. They not only expand the list of nozzles available for use, but also facilitate the process of changing them without connecting an additional tool.

To carry out pinpoint operations under heavy load, electronic speed control will also be required. This function is useful if you plan to work with materials of different degrees of density. The most modern versions automatically adjust to the working basis by estimating the pressure on the drill and the degree of pressing the start button. Another question is no less important - how to choose a hammer drill for homework, taking into account auxiliary functional accessories? In this part, it is worth providing for the laser guidance of the drilling point, LED illumination and a safety clutch. All this contributes to high-quality drilling with precise centering of the working body. For greater reliability, an anti-vibration system should also be provided, which reduces the effect of vibrations on the accuracy of the orientation of the drill.

Model Makita BHR242RFE

A device with an unusual configuration of power stuffing, which combines a balanced design and high power with a low impact force of 2 J. Users consider it the borderline version of an impact drill between the professional and household segments. That is, if there is a question about how to choose a good universal-purpose puncher, then you can refer to this particular proposal. Operational Feature in that the power filling is focused on performing short operations, but with high peak power. For comparison, complete professional models designed to withstand high loads over long working sessions.

Also this model represents the accumulator class. The lithium-ion unit has a small energy reserve of 3 mAh, but this is enough for the same household repair activities. An additional battery is included in the kit. Here it is important to reveal some of the nuances of the non-stop operation of rotary hammers for the home. Which device to choose in terms of autonomy? It is desirable that a balance be struck between capacity, charging time and the duration of the workflow. It is this advantage that distinguishes the BHR242RFE modification. While the energy of one block is replenished, the master can work with the second for several hours. As for other advantages, the model is also equipped with vibration protection, dust isolation and thoughtful body ergonomics, which traditionally distinguish Makita power tools.

Model Bosch GBH 18

This device has a blue color, which indicates that it belongs to a professional group according to the German manufacturer's proprietary classification. However, the cost of 14 thousand rubles. allows many home users to acquire such an assistant. Moreover, in terms of ergonomics and optimization, this is one of the best rock drills with a lightweight design. Yes, the performance is low - only 1.7 J at 18 V. Also, the processing parameters are not impressive - for concrete, the drilling diameter is a maximum of 20 mm. But these modest indicators for domestic use are not a critical limitation, but in return the owner receives a small, light (2.3 kg) and maneuverable body, as well as a high spindle speed, which allows you to work with small drills. Quite often, professional builders are faced with the question of how to choose the right hammer drill in order to get both a balanced design and not lose power. Of course, in this case, things are not very important with performance, but the convenience of physical handling is on highest level. As the users themselves note, the GBH 18 puncher can be operated even with one hand.

Model "Interskol" PA-10/14,4R-2

Solid domestic rotary hammer, made on a battery basis with the basic functionality of an impact drill. The robust body of the tool provides protection from physical damage, the mode switch is responsible for setting, and the shanks are fixed with a quick-release chuck. By the way, the SDS-plus retainer accepts drills with diameters of 5, 6 and 8 mm. Also for work in hard-to-reach places the developers have provided a backlight. What is also important in this model is the operational versatility with a wide coverage of work operations - this is also confirmed by reviews of the rotary hammer. Which tool to choose for both impact drilling and fastening hardware? This is a popular question of ordinary home craftsmen who do not need specialized functions, and the “omnivorousness” of the device comes to the fore. And the creators of the model under consideration just offer the performance of various tasks at an average power potential. As a result, concrete with metal can be processed with a diameter of 10 mm, and wood - up to 20 mm. And within the same production process, without changing the tool, the operator will be able to be distracted without a hitch and to tighten the screws.

Model DeWALT D25144K

This time around, the focus is on high performance, as evidenced by the 3.2 J impact mechanism, supported by a 900-watt engine. The perforator also works successfully in shockless mode, which can be switched to after replacing the standard SDS-plus chuck with a conventional three-jaw grip. In other words, this is the same universal design that is suitable for working in screwdriver mode. But, small-format fast operations with constant movements around the site are not the best format for using this version. Yet the design of a powerful impact drill is designed for more solid tasks. And how to choose a rotary hammer for repair, so that it combines compactness, lightness, versatility and performance? On the one hand, this is a contradictory combination of characteristics, and on the other hand, the rejection of the battery pack while maintaining the usual network drive, at least guarantees not to exceed the weight at average power. It is in this configuration that the D25144K modification is proposed, but, as users note, you will have to pay for ergonomic advantages with strong vibrations and noisy operation.

Model AEG PN 11 E

It should be noted right away that this puncher belongs to the highest class and is estimated at 45-50 thousand rubles. What does the owner of this unit get? 1700 W motor, 27 J impact energy and 11 kg of weight. That is, the model has practically no restrictions in terms of application - at least within the framework of tasks that, in principle, are available for a perforator as such. At the same time, the owners do not so much emphasize the versatility with a wide range of operations under their control, but the ease in solving quite standard repair tasks.

Of course, for such a cost, you can count on the presence of innovative systems. The wear indicator of the carbon brushes of the gearbox, the idle speed limiter and the soft start are just some of the useful options that are positively noted in the reviews. Which hammer drill to choose for the home, so that it combines reliability, endurance and ease of manipulation - too frequently asked question, which are given by amateur masters who understand a lot about these qualities. It cannot be said that the AEG PN 11 E demonstrates record performance and can compete with small-sized counterparts in terms of ergonomics, but the developers still found a certain balance. Despite the weight of 11 kg, the model effectively copes with drilling tasks without a heavy load on the hands - this is facilitated by the thoughtful design of the body and the high speed of the operation.

Rating of the best models

Each of the above models has its own advantages in different aspects of the application. Their combination, taking into account the cost, will answer the question of how to choose a hammer drill for homework. The rating below focuses on the most popular and high-quality models available on the market for ordinary users:

1. Bosch GBH 18. The main quality of this device is balance. It concerns both the immediate working qualities and the price tag. The model is a little beyond the cost range of a strictly domestic class, but a modest overpayment for high German quality fully justifies itself.
2. Makita BHR242RFE. The Japanese brand is a direct competitor to Bosch, but the class of this model is higher than the previous offer. The difference in price is 10 thousand rubles, and this, even taking into account higher operational data, is not suitable for every amateur master.
3. "Interskol" PA-10 / 14,4R-2. Against, a budget option which is in good demand. But, this rotary hammer still cannot compete with Makita products in terms of reliability and durability of the element base.
4. AEG PN 11 E. For unique combination characteristics and an abundance of modern functions with increased performance, this device also deserves a place in this rating, but taking into account the price tag, it is far from the first position.
5. DeWALT D25144K. In general, a good model that can compete with each of the analogues below in terms of individual qualities, however, the imbalance in the balance between ergonomics and power makes it a specific proposal designed for a narrow segment.

When evaluating these options, you should rely on your workflow requirements. In some cases, performance will come to the fore, in others - reliability, and in others - functionality. Perhaps, as a compromise solution, it is worth choosing a Makita puncher worth 24-25 thousand rubles. This is a lot of money for home appliances, but you can be sure that all hammer drilling tasks will be completed without unnecessary worries.

Conclusion

A perforator is a tool that is certainly useful and in some way irreplaceable. However, the average homeowner needs it only on rare occasions. More often, a standard electric drill is used, which is cheaper, more manageable and lighter. How to choose a perforator for apartment renovation in order to cover as many tasks as possible? You can go in a slightly different way. The main difference of the perforator is the presence of the function of the percussion mechanism. But today it is also provided for some drill models. For example, battery versions with a voltage of about 24 V may well replace a corded puncher. For right choice it is only necessary to calculate specific technical parameters and superimpose them on the processing capabilities of target surfaces and building materials.
