Which puncher to choose for a home master. Which hammer drill is better to buy for home: an overview of characteristics and firms

When repairing an apartment and a house, probably one of the most popular power tools is a hammer drill due to its versatility, for drilling hard materials (, metal), soft materials(plastic, wood), chiselling, for example, breaking tiles.

In this article we will consider the question of which puncher to choose.

Perforators are divided into household low power from 450 W to 1000 W, small in weight from 2 to 4 kilograms, with an impact force from 2 J to 3.5 J, and professional from 1000 W to 3000 W and weighing up to 12 kilograms, with a force shock from 4 J to 20 J.

Also, rotary hammers differ in the type of engine location, these are:

Horizontal arrangement most common and used in household punchers. Such a scheme is the most compact and convenient for operation, however, the disadvantage is an increased shock load on the engine and worse cooling. The impact mechanism is usually using an oscillating bearing.

Modern rotary hammers usually have 3 modes of operation:

1. Hammer drilling (basic mode);
2. Drilling (drill);
3. Blow (jackhammer);

Most often, hammer drills have two or three modes, single-mode, as a rule, this is a professional tool sharpened only for drilling with impact, which does not have additional devices and mechanisms and, as a result, is more reliable and durable.

Perforator body

Most often, the body is made of several materials. These are metal (aluminum alloys), hard plastic, soft plastic.

Anti vibration system

Vibration protection systems are divided into active and passive.

Active systems (AVS) are installed on powerful models. This is a shock-absorbing device, a counterweight with a spring that absorbs recoil.

The passive system is a set of all possible rubberized pads, handles, which, in addition to anti-vibration properties, allow hands not to slip.

So, having considered the technical parameters, I would like to touch on one more important parameter: tool cost.

The cost of a household tool starts from $50 to $250. The cost of a professional tool reaches $ 1,000.

Nevertheless, you should not buy the cheapest one, even if you do not have plans for a global restructuring of the apartment. Most likely, it will not serve you for a long time, and in case of intensive use it will not be able to help you at all. Take a closer look at the puncher in the middle price category.

For almost all work that may arise on the repair of an apartment, a rotary hammer from 1000 W to 1500 W with a horizontal engine will suffice.

This will allow you to work in narrow places, with a shock energy of 2-3.5 J. A nice bonus is the ability to have three modes of operation and reverse.

A hammer drill is a percussion tool designed for long-term drilling of hard materials (concrete, stone, etc.).

Perforators belong to the class professional power tools and are many times superior to conventional household drills in terms of technical characteristics, and therefore, are more expensive.
The fact is that for a drill, the percussion function is additional, and for a perforator, it is the main one. If the main purpose of an impact drill is drilling, then a hammer drill is chiselling. The drill has an electromechanical percussion function, and the perforator has an electropneumatic function. With the same tool power, the diameter of a hole made by a hammer drill is approximately 1.5 times larger than that of a hole drilled by an impact drill.

Features of rotary hammers

The power and other technical characteristics of the selected rotary hammer depend on the purpose of its acquisition.

Modern full-featured rotary hammers have three modes of operation:

• blows without rotation (work in the mode of a jackhammer),
• rotation without impact,
• rotation with punches.

A hammer drill can be used for more than just drilling various materials, but also for other works - gouging niches or strobes in stone walls, chipping off excess material, etc.

You need to consider when choosing:

• Rotation speed adjustment. It is better if the tool has a button lock at maximum speed.
• Stop switch. This function allows you to fix the switch in the position you choose

Important indicators:

• Heavy hammers work with powerful drills, but such work takes a lot of strength.
• When choosing a hammer drill, look for the sweet spot between the tasks you need and the amount you're willing to spend on the tool.
• Hammer drills are very different configurations. The basic package may not include the features you need. Carefully study the characteristics of each specific model.

The puncher is indispensable tool during home renovation or construction. With its help, various holes are made very easily in concrete, brick or stone surfaces. In order to correctly choose a tool for certain types of work, you first need to know what types of rotary hammers the industry offers.

Although the purpose of these units is the same (drilling, drilling, chiselling), they differ in their functionality, which affects the scope of their application.

Cordless Hammers

Battery-powered devices (batteries) can be classified as household power tools.

A cordless hammer drill is convenient to use in places where there is no electricity, but it is worth knowing that the tool is designed for a short operating time. With it, you can only make a few holes in the wall. For work on hard materials, which imply a long operation of the device, it will not work.

The main advantages of the device on the battery:

• independence from the mains - can be used in the country, in the garage, with roofing works etc.;
• sufficient power;
• light weight;
• compact body;
• the presence of a reverse;
• it is possible to drill concrete (maximum diameter 10 mm);
• has a speed controller.

Disadvantages of the device on the battery:

• the operating time of the device is limited by the battery capacity;
• inconvenient for frequent use, since it takes time to charge the battery;
• when dropped, the battery fails;
• Difficulty purchasing a spare battery.

Network devices

This type of device is most in demand both for homework and professional use in the construction industry.

Thanks to the constant supply of electrical network, the units have good performance and have big power. Network punchers are widely used in construction and repair work, make it easy to ditch and drill walls, as well as punch openings in them.

Advantages:

• high performance;
• affordable price;
• most devices have three modes of operation (drilling, drilling + impact, impact without rotation of the cartridge);
• anti-vibration system;
• the ability to adjust the speed.

Disadvantages:

• the power cord restricts movement;
• with unstable voltage in the network, performance decreases;
• during long and frequent work, the chuck wears out, as a result of which the fixation of the drill weakens, and the chuck needs to be replaced.

Pneumatic rock drills

Air tool works from compressed air . For this reason, it can only work in tandem with a compressor.

This type of tool is used in places where, due to the risk of explosion, it is impossible to use power tools.

Often pneumatic units are used when working in damp rooms, for example, flooded with water.

Advantages:

• light weight;
• high spindle speeds and high frequency beats per minute;
• can be used in damp rooms and places with increased explosion hazard.

Disadvantages:

• a compressor is required for operation;
• hose length restricts movement;
• high cost of the unit.

Gasoline devices

Units that have a two-stroke gasoline engine as a drive have great power and high strength hit.

Advantages:

• mobility due to independence from the compressor and the mains;
• one filling of the tank allows the unit to work for about 2 hours;
• swipe;
• three operating modes.

Disadvantages:

• high price;
• big weight;
• the impact force is not adjustable, which may cause unnecessary cracks in the treated surfaces;
• the need for a canister with additional fuel;
• material costs for the purchase of fuel;
• large dimensions.

Classification by engine location

In addition to the power source, devices can also differ in the location of the engine: they are pistol-type and barrel-type.

Pistol type apparatus

In these perforators, the engine is located horizontally, and the percussion mechanism (located in the barrel of the unit) is driven by "drunk" bearing, to which rotational motion is transmitted from the rotor.

If you look at the barrel puncher, you can see that the engine is installed in it at the bottom of the unit. Vertical electric drive makes it possible to most effectively use the crank mechanism (KShM) in order to engage the impact block.

The rotational movements of the engine rotor are transmitted to the crank, which, converting them into reciprocating movements, transfers them to the piston. The latter actuates the percussion mechanism located in the barrel of the apparatus.

Important characteristics of rotary hammers

In order not to overpay money for unnecessary power, or vice versa, not to get the desired result due to low power apparatus, it is necessary to study the main characteristics of the apparatus and what they affect.

Impact strength

This parameter indicates the force with which the equipment (drill or pick) will be immersed in the material being processed. Impact force is measured in joules (J). The value of this indicator depends work speed. AT professional field many holes have to be drilled per day and large openings have to be made. Therefore, it is necessary that the device has an impact force of 4 to 17 J. A perforator with an impact force of 1-3 J will be enough for the house.

Power

The impact force directly depends on the power of the engine of the unit. Perforators are usually divided by power into 3 classes.

1. Light apparatus have a small power, on average up to 0.8 kW. They weigh about 4 kg and can develop an impact force of up to 3 J.
2. Medium perforators have a power of 0.8 to 0.9 kW, weigh up to 8 kg, develop an impact force of up to 9 J.
3. Heavy aggregates- these are devices with a power of 1.2 kW and above. They have a weight of more than 8 kg, and an impact energy of more than 17 J.

Impact frequency

The performance of the tool also depends on the frequency of impacts. Even when the impact force of the unit is high, with a low frequency of impacts, work with such a tool will be slow. Therefore, this indicator is very important for the professional use of a rotary hammer, and should be about 5000 beats per minute. At the same time, a home appliance can have 3-4 thousand beats per minute.

Rotational speed

This figure is much higher for household punchers. This is explained by the fact that at home the device will more often be used as a drill. Therefore, for household devices, a rotation speed in the range of 1500-2300 rpm is available. For professional equipment the spindle speed is in the range of 750-1100 rpm, since the priority is given to the shock functions of the machines.

Operating modes

Most units have 3 modes of operation.

1. Hit. In this mode, the equipment performs only translational movements, as in the case of a jackhammer. There are no circular spindle movements.
2. drilling. The machine spindle rotates. This mode allows you to use the unit as a drill, as well as for drilling with diamond core bits.
3. Drilling + impact. This mode combines 2 functions. It is usually used for drilling holes in hard materials using special drill bits.

You should be aware that there are models of punchers that have only 1 or 2 modes. Therefore, we choose a device with three modes: with its help, you can solve more problems.

Chuck type and drill diameter

In perforators, it is customary to use SDS cartridges. The abbreviation SDS is translated from German as "insert, turn, fasten." Clamping chucks are divided into 5 types:

Additional options

The characteristics that have been described above are key. And in order to choose the right punch, you need to pay attention to them. But there are also additional options that should be considered when buying a device, as they can significantly increase the convenience of work.

1. The presence of a reverse. This option is optional, but recommended. With its help, the drill is pulled out more easily from deep holes. To do this, it is enough to turn on the reverse rotation of the machine spindle.
2. Jamming protection. This feature is very important if you have opted for a high power unit. When the tool is jammed in the material being processed, a special clutch can prevent injury to the master and burnout of the motor windings.
3. Speed ​​shifter. With it, it is possible to regulate not only the speed of rotation of the spindle, but also the frequency of impact.
4. Smooth start avoids jerking the tool when starting.
5. Speed ​​stabilization system. This function keeps the spindle speed at the same level, regardless of the load on the tool.
6. Stop button for switch allows you to fix the start button in the working position, and further holding it with your finger is not required.
7. Anti-vibration system essential for a professional instrument. Thanks to it, the master will feel much less vibration, which, as you know, affects not only muscle fatigue, but also human health in general.
8. Emphasis allowing you to control the drilling depth.
9. The presence of a dust collector. A hammer drill with a dust collector allows the master to more comfortably carry out the work of drilling walls, since this operation generates a lot of dust. Nozzles have a branch pipe for connecting a vacuum cleaner to them, and can have a different design.

The best manufacturing companies

The number of perforator manufacturers is steadily increasing every year. But self-respecting professional craftsmen give preference to a tool that has been tested in practice for years and has good feedback from the owners. The review below includes the most popular manufacturers of devices in 2016-2017.

First of all, if you are confused about which hammer drill is better to buy, decide for what use you want to purchase a tool: for household or professional. Usually, household tool does not withstand heavy loads and is designed for short-term operation, no more than 25 minutes. After that, the engine should be allowed to cool down for about 30 minutes. Besides, home appliances should not work more than 4 hours (in total) per day. At the same time, a very powerful tool is not needed for home use.

Professional construction puncher can be used to perform large volumes of work, including as a jackhammer, since the unit is able to withstand large and hours-long loads. There are several ways to distinguish a professional hammer drill from a household one:

• price - household power tools are much cheaper than professional ones;
• a pro-class device is distinguished by high power and considerable weight;
• professional units have increased impact force, which increases their productivity.

Perforator for home

Tool for home use- These are devices of light and medium level, in terms of weight and power. If you occasionally need to use this tool for concrete or masonry chiselling, it is recommended to purchase a pistol-type machine that has following parameters and design features:

• engine power should be in the range from 0.6 to 0.9 kW;
• impact force - from 1.2 to 3 J;
• the device must have 3 modes of operation;
• impact speed can reach 5000 beats / min;
• there must be an adjustment of the spindle speed;
• spindle speed should be 1100 rpm and above;
• the presence of a clutch that prevents jamming is welcome;
• the device must have a keyless chuck and be sold with a replaceable chuck;
• it is necessary to have a button for fixing the trigger;
• comfortable handle that can be easily rotated to any position;
• the presence of a reverse (the ability to turn on the reverse rotation of the spindle).

Hammer drill for work

A professional hammer drill, both horizontal and vertical, must be able to work within the ranges listed below (these are generalized parameters within which pro-class tools work):

• the impact speed should be from 1000 to 5000 beats / min .;
• spindle speed from 750 to 1100 rpm;
• impact force from 8 to 17.5 J;
• power consumption from 1250 to 1500 W;
• weight from 6.9 to 10 kg;
• maximum drilling diameter in concrete from 45 to 80 mm;

Also, the device for professional use must be equipped with anti-vibration protection and anti-jamming.

If you are seriously thinking about carrying out repairs, then you should pay attention not only to the development of a design project for a dwelling, the choice of construction and finishing materials, but also the acquisition of a special tool, without which you simply cannot do. Such equipment can be safely attributed to a perforator, which, being a percussion tool, easily copes with the removal of plaster, concrete chasing, chipping of bricks and a number of other serious construction works. And let many believe that for these purposes it is enough conventional drill, yet the puncher differs radically from it both in the way it works and in the price. So, you should understand the intricacies of the work of such a tool, taking into account the specifics of the upcoming work.

Perforator and its difference from an impact drill

To begin with, we propose to consider the differences between a drill with impact action and a rotary hammer. Impact drill works on following principle: The tool contains two toothed ratchet that are in contact. Working with a drill in impact mode, you create pressure with it on the surface to be treated, forcing the tool to jump "on their teeth". Serious disadvantages of this principle of operation are the small impact amplitude, high level vibration during operation, as well as significant physical effort that will have to be applied to drill hard materials. Yes, and the constant interaction of the drill with hard surfaces leads to rapid wear of the ratchet teeth, and these are additional costs for their replacement.

The perforator does not have all these disadvantages, since its internal organization fundamentally different from a drill: so the mechanism of an electro-pneumatic hammer drill is in some way similar to an automatic weapon device.

First of all, a hammer drill is a very powerful and durable equipment designed for drilling holes of any size in hard materials. The impact of perforators is much lower, and the speed of passage is much higher. Another advantage of the hammer drill is the head for fixing the drill or drill. While hammer drill equipped with a cam lock, a reliable replaceable SDS-chuck is installed in the perforator, which allows you to quickly replace the drill or cartridge directly.

Perforators are used for drilling holes in concrete, stone, brick. Since the destruction of concrete most effectively occurs from impact, then working part the drill of a construction puncher looks like a chisel. During rotation, the chisel forms round hole. Thanks to the spiral grooves on the drills, chiselling products are removed from the hole, and productivity is also increased.

The fundamental principle of the hammer drill

From a technical point of view, the drilling process looks like this: the electric drive of the device provides a reciprocating movement of the piston, while vacuum and an increase in air pressure alternately occur, bringing into operation the second piston - the "striker", which strikes the equipment shank, thanks to air gap a damping effect is created between the striker and the piston. It is he who reduces the shock loads on the piston, and as a result, increases the "viability" of the piston drive mechanism.

In order to decide for yourself which rotary hammer is better, we recommend that you familiarize yourself with the basic technical specifications perforators:

1. rated power - the high power of the rock drill indicates a high drilling speed, and vice versa. However, at the same time, attention should also be paid to the weight of the unit - powerful punchers are quite heavy, which means that only a physically trained person can work with them;
2. idle speed;
3. the diameter of the holes obtained for materials of various densities and thicknesses in the impact mode.

In addition, in order to understand which hammer drill is the best, you should pay attention to some of its functions, which are indicated directly by manufacturers. construction tool. These include:

1. depth gauge mounted on a puncher. Allows you to accurately determine the fact that the drill has reached the desired depth;
2. speed switch. Performs the function of regulating the speed of rotation depending on the types of work: for example, it is better to drill small holes on fast speed, and for deep ones it is preferable to set a slower speed. Today, manufacturers equip drills and hammers with special processors that can automatically set the speed of work depending on the parameters you specify;
3. "reverse rotation". Thanks to this function, the process of removing a stuck drill will no longer cause you difficulties;
4. Removable side handles. They are designed for convenience during work and can be dismantled if you have to work in a limited working area;
5. "wireless" devices. Ideal for working at heights with limited wires;
6. drilling/chiseling switch. Some models of obsolete punchers do not have this function, which means that when choosing a construction assistant, you should pay special attention to this.

Which is better to choose a perforator

Product High Quality when checking the performance, it is characterized by the presence of even noise, without any dips and further amplifications, possible knocks that can be transmitted to the body of the product. Such equipment, already selected for noise characteristics, should be subjected to an additional test: turn on the hammer drill in the network, and after reaching maximum speed, turn it off. Special attention notice how the tool stops working. Turnover should decrease gradually, smoothly. When the engine is turned off, the last stages of the stop should be accompanied by a distinct noise of all working units. In no case should the equipment stop dead in its tracks.

According to the class, perforators are usually divided into:

• lungs,
• medium,
• heavy.

to light class belong to instruments weighing no more than 3 kilograms. These models are designed to be concrete surface holes of small diameter and may have functions that are inherent in drills.

Middle class available in models weighing up to 5 kilograms. They are used for more heavy work: e.g. for drilling reinforced structures from concrete.

For heavy vehicles perforators weighing more than 5 kilograms can be attributed. Such a model can perform the functions of a jackhammer and be used for the most difficult jobs. Some manufacturers of rotary hammers offer customers models of all classes, for example, a Makita rotary hammer, interskol and bosch.

When choosing between a non-professional and professional model of a rotary hammer, remember that professional units are able to withstand longer loads, and their cost is an order of magnitude higher than non-professional machines.

In addition, professional hammer drills have the following options:

1. control electronics designed to accurately start work and control the impact force;
2. constant (constant) electronics used to maintain a pre-set parameter in the event of load increase, inrush current limitation, start softening and reliable protection from overheating;
3. impact blocking for drilling in wood or steel;
4. safety clutch release;
5. adjusting wheel to select the optimal number of revolutions, strokes or force of strokes;
6. switch-off device, rotation lock for comfortable and safe installation of the chisel in working position and its fixation;
7. rotation direction switch (reverse) designed to release a jammed tool and for receiving work additional function screwdriver.

Household grade rotary hammers have a fairly limited resource continuous work, they are not used to perform professional work, but are indispensable in household. And one more axiom: the cheaper the equipment, the more difficult it is for a professional to carry out the task.

How to distinguish professional models from non-professional ones? It's simple - manufacturers often mark them with different colors.

Hammer drills from well-known manufacturers

Makita 2450 perforator device

Hammer drill Makita HR2450 created for conventional drilling, percussion and chiselling. Basically, the model can be professional tool, representing "3 in 1": jackhammer, drill and impact drill. The simplicity of the model hides reliability, quality and affordable cost.

The model is equipped with built-in electronics - rotation speed control system. Rendering required pressure on the "trigger", the "smart" model instantly responds, increasing or slowing down the number of revolutions. This feature allows you to work more efficiently with materials of different densities.

The Makita HR 2450 perforator is equipped with an SDS-plus chuck, which performs a quick change of working nozzles. Equipment Makita HR2450 is characterized by durability and high performance and reliability, the model is comfortable to use due to the equipment of a disengaging clutch that provides slippage of rotating mechanisms and prevents jerking. A sudden blackout in the mains will result in the activation of the interlock system, which prevents accidental activation of the equipment.

And if you add to this 40 possible angular positions of the nozzle, which are provided in this model, then you will get the answer to your question “which hammer drill is better to buy for home”.

Bosch puncher device

Kill two birds with one stone in pursuit of true German quality and affordable price only one is possible possible way- get a professional rotary hammer Bosch. It was under this brand that the first rotary hammer with a pneumatic impact system was manufactured.

Bosch perforator device Ideal for both home renovations and professional activity. For example, for home use, you can choose a professional Bosch rotary hammer, which costs just over $ 100 and has a power of 0.5 kilowatts. Professional Models, of course, are several times more expensive, but their power is much higher - 1.5 kilowatts.

In terms of equipment performance, the Bosch 2000 rotary hammer model performs 2300 rpm and 5800 strokes. The machines work effectively with drills with a diameter of 20 mm in brickwork or concrete.

The models of rotary hammers Bosch 2400, Bosch 2800 and Bosch 3000 have an average power. At the same time, the engine power is 720 watts, and a large pneumatic impact force of up to 2.6 J allows you to work with high-strength materials: hard rock and reinforced high-strength concrete. The models are ergonomic, have a number of improvements and differ in the number of engine revolutions per minute. So, the Bosch 2400 rotary hammer model supports the rotation of the drill at a speed of up to 900 rpm, and the Bosch 2800 and 3000 models - from 0 to 1450 rpm.

In professional circles, the most effective is the Bosch 2-24 rotary hammer, available in two versions DFR and DSR, and the Bosch 2-26 tool (DFR, DRE and DRE-SET). The Bosch 2-24 rotary hammer model with a power of 680 W operates at low speeds - up to 870 per minute, however, a sufficiently large impact force turns it into a very effective tool when chiseling or drilling high-strength materials.

The Bosch 2-26 rotary hammer is an even more efficient machine - the engine power is 0.8 kW and the optimal scheme of the impact mechanism (3 J impact, 4000 beats per minute) contributes to the formation of holes with a diameter of 26 mm. These devices can be used as a jackhammer.

Perforator device interskol

Lightweight Dual Mode Interscope Models horizontal arrangement are equipped with a clamp under SDS shanks- Plus and shock mechanism of compression-vacuum type.

The layout of the equipment is traditional with a horizontal engine. The reverse allows you to easily remove stuck drills, and after installing a screwdriver bit and a drill chuck, the tool turns into a powerful and affordable screwdriver. Such a machine is deservedly considered “one-handed”, since it can even be operated with one hand. A small impact energy allows you to create holes in the range of 4-12 mm - for the most common dowel options. Drilling productivity averages 25 cubic centimeters of concrete per 1 minute when drilling holes of medium diameter. A six-millimeter drill in less than a quarter of a minute goes into concrete by 8 cm.

The impact force of 1.2 J indicates the relative low noise of the tool and the low level of vibration. The perforator of the Interskol line, due to its lightness and ease of use, is quite suitable for both domestic use and for professional work.

So, what is the best hammer drill to buy?

No matter what model of puncher you decide to purchase, bosch tools, interskol or Makita will become indispensable assistants for household and professional work when drilling sufficiently hard materials of hardness. With him, the work will move easier, faster and better.

However, before making a final choice the best firm- manufacturer of rotary hammers, find out in your city about the availability service centers service for a specific company. Ask if there is a warranty this model And what is the warranty period.

Youtube video will help you choose best puncher for specific purposes.

The Stone Age is over and now a lot of devices have been invented for easy and high-quality work. A perforator is a tool that no builder or repairman can do without. But how to choose it and what to rely on when choosing? What qualities should be taken into account in the first place, and which ones can be omitted? The principle of operation of the tool and design features are further in the article.

A hammer drill is a tool that is used to drill into walls. It is impossible to combine a hammer drill and an impact drill - a different principle of operation. Perforator drill solid material: concrete or stone. Hammer drills are an order of magnitude higher than a conventional drill because of the class and technical characteristics. For example, an impact drill just drills, and a hammer drill hammers. Even according to the characteristics of the main function, these two things are different and should not be confused.

It is necessary to take into account when choosing a puncher modes. Just punch, punch and drill, punch-drill-chisel.

The weight of the perforator plays an important role when choosing a tool. Heavy rotary hammers can weigh more than 10 kg. Considering all the main characteristics, you can choose good tool for construction. Perforator, for work at home, a necessary thing. But when choosing it for personal use, it is necessary to take into account many qualities: what the walls of the house are made of, the severity of the tool or work, love for neighbors.

To navigate the whole variety of punchers, you need to start with the tool class. Perforators of the usual class do not exceed 4 kg in weight. The choice of such a puncher is due to household needs. It is bought specifically for working at home and punching holes and openings. Perforators of a higher, middle class already weigh more than 5 kg. They are better at breaking through walls and even gratings. Tests show that they can be used to remove bumps from concrete walls.

And the instruments of the highest class are real heavyweights. Weigh over 8 kg. The principle of operation of such a perforator is to punch a hole in any wall and surface with any density and hardness. It is intended for professional use. For work at home, a low-class tool is suitable, but with a number of qualities. A certain power and force of impact.

According to what characteristics choose a puncher for the house:

• The power of the perforator should not exceed 800 W;
• Impact force in the limit of 1-2 Joules;
• Three modes of operation - rotation, rotation and impact, impact without rotation;
• The regulator on which the speed depends;
• Protective sleeve for drill;
• SDS-Plus fastening system.

Having similar characteristics, the puncher will easily cope with all household tasks. For home use, you can buy an inexpensive, but high-quality tool.

Tests: which puncher is better

To repair an apartment, it is better to prefer two firms with a high rating and positive reviews. These brands are called Bosch and Makita. A household product of any of these companies, on the counter, differs from a professional product only in color. This difference makes it easy to find the right counter with the right tool. Makita punchers are made in Japan. They are great for light renovations at home, office. Drilling holes, hanging shelves for this workaholic is not a problem.

Characteristics of Makita perforator:

• It has a power of up to 700 watts;
• Impact force of 3 J;
• Revolutions 4500 per minute.

Very light and inexpensive, has a lot of advantages. Powerful, reliable and does not take up much space.

Bosch rotary hammers have been tested by time itself. They are made according to super modern schemes and technologies.

They say they work forever. The exact number of rotation of the drill will help you accurately drill to the desired depth. If the puncher of blue color, then a real puncher can work with him. They say that as soon as they pick it up, there is a desire to drill through all the walls in the house and break what will fall under rock. It is powerful, unkillable, reliable and very innovative. Such a puncher is needed by any person who correctly makes repairs in the house.

The principle of operation of the perforator

When working with a puncher, you need to understand the principles of its operation. Engine location: vertical or horizontal engine. How much it weighs and how to use it, how many modes. All these qualities must be considered when working with a puncher. An inexperienced user may not know all the mechanics of each screw in it, but understand which modes are necessary for a particular type of work.

Operating modes and their features:

1. drilling mode. Usually, this mode should be selected for simple operation. In work, you do not need to put much pressure on the product. The chuck can be damaged if it rotates counterclockwise. The blow will also be inappropriate, it must be blocked with a special button. Before work, you need to check the mode and gearbox, there are times when you just need to drill a hole, and the mode is wrong. Then the surface deteriorates.
2. Drilling and impact mode. Usually indicated with a hammer and drill. To work was safe, you need to monitor the warp of the drills. This is due to the reinforcement in the concrete.
3. Impact mode. When you want to finish off, ditch and make as much noise as possible, use the impact mode. You need to grab the punch very firmly and put the mode on the hammer. In order for him to stop lightly drilling the walls and perform jacking work, you need to put pressure on him.

So, three modes and three types of work. It all depends on the pressing force and the location of the toggle switch. Safety precautions require you to carefully study each mode and choose the best one for you. independent work. After all, you can carefully drill a hole, and at the same time use impact and drilling.

Impact drill or hammer drill: what to choose

When it is necessary to make holes in the surface, use a puncher or a drill that works on impact. The rotation of the main element in these products is based on the impact on the horizontal axis. Many do not distinguish between these instruments, not noticing the difference. Confusing and not understanding the features, you can purchase an absolutely unnecessary tool by spending a large amount of money on it.

Differences between a hammer drill and an impact drill:

1. Impact mechanism. The main difference is in the type of impact. Perforators are based on very complex units - electromechanical or electropneumatic. The rotation of the electric motor forms the movement of the piston. The piston energy is transferred to the drill and drill. With a drill, everything is easier. Two ratchets, each of which is connected to its own element - a drill body or a rotation chuck. As soon as they are in contact with each other, the impact movement begins. A reciprocating motion is transmitted to the chuck, and then to the drill, and the impact mode works.
2. functional differences. Hammer drills have three modes of operation, and a drill has two. Perforator drill, chisel, chip. The drill is less functional.
3. Performance. Of course, an outlet is required for each product to work. In terms of performance, the hammer drill exceeds the drill. This is especially noticeable when drilling stone. The energy expended by the perforator depends on the force that is applied to it when pressed. With a drill, it is insignificant. Small or large pressure, it doesn’t matter at all - the amplitude of the drill when moving along the axis is quite small. Hammer mass also affects performance and exceeds the mass of the drill.
4. Fixing tools. For a puncher of all modes, a great variety. You can’t say the same about a drill: a drill with hardfacing and nothing more. The puncher has drills and other devices in special cartridges. The SDS-max system allows quick tool changes. They are fixed with special recesses. There are quite a lot of advantages for a hammer drill over a drill due to greater opportunity work with various tools.
5. Ease of operation. And at this point, the hammer drill will leave the drill far behind. It would seem that such a great use of the modes and a lot of different additions. What could be simpler than a drill and its ordinary drill. But it all depends on pressure. You can work with a puncher and practically do not press it. The drill requires more powerful influence.

All these characteristics incline the buyer to purchase a puncher. Even its service life is higher than that of a drill. Ratchets wear out quickly and become unusable. And the pneumatics of the rock drill ensures its reliable and long work. The price is the only plus for the drill. Miser pays twice. You should not buy a cheap tool, but after a while replace it with a more expensive and reliable one. It’s easier to take a quality one and not change it for centuries.
