Which puncher to choose for a home master. Which hammer drill is better to buy for home
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 of 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:
- Hammer drilling (basic mode);
- Drilling (drill);
- 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. 
Perforator - is a very necessary tool used for drilling various holes. By its principle, the tool is similar to an impact drill, but these devices are not interchangeable. In this article, we will deal with the task - how to choose a suitable hammer drill for homework, which device to choose for apartment renovation, and also consider all its defining characteristics.
General information
Perforator - a device that allows you to drill holes of various sizes and depths, in various materials. The intended purpose of the device is the drilling of materials with high strength and rigidity (for example, concrete). Today, the most common types of these devices are devices with a pneumatic and electric mechanism, which provides impact drilling of the material. Many consumers are concerned about the question: "How to choose a hammer drill for the home?". Uncertainty comes with one kind a large assortment proposed models. After all, each of them differs in performance, as well as various technical features. Therefore, to make a choice of a good rotary hammer, it is necessary to consider a number of factors.
Impact drill or hammer drill?
These two devices needed for repair have fairly similar parameters, but at the same time they are different.
- Drill - a smaller and less weighty device, applicable, as a rule, for drilling not very durable materials. Its impact function provides very little drilling assistance.
- The hammer drill, in turn, has a large drilling and impact power, while it has the function of a non-impact drill. When buying a device, you can save cash, which would have invested in the purchase of both devices. The powerful drills used in the devices will allow you to quickly and easily make the necessary holes in shape and depth.
How to choose the right power
The power of the device is one of the basic parameters. A fairly wide range of device powers is presented on the market: from 450-500 W to 2000-2500 W. As a rule, models with a power of 450-600 watts are suitable for the home. All models with higher power can be called professional. Such devices allow for faster and deeper drilling. For infrequent drilling work, you can completely use a low-power model.
Decide on the type of device
The choice of a good rotary hammer is influenced by its variety of engine location.
There are two such types:
- Horizontal motor model, suitable for short and narrow drilling. In such varieties, the engine is located along the shock axis, which contributes to a low level of cooling. During long-term work, this type of engine must be allowed to cool, otherwise it may fail.
- Model with a vertical arrangement of the engine. In such devices, the engine is located, respectively, perpendicular to the shock axis. These devices have such advantages as higher power and no need for constant cooling. Therefore, such varieties are more often used in conditions where uninterrupted operation and high shock power are required.
About the force of impact
Striking power is one of the determining parameters when choosing a reliable device. However, more power means more tool performance and therefore more energy consumption. The more there will be operating power, the deeper and larger in diameter it will be possible to drill. At the same time, one should not forget that such high-power devices will have large dimensions and have a large mass.
How to choose a hammer drill for concrete
When choosing required model, you should pay attention to its labeling. For concrete, marking is required - SDS +. With such a device, you can not only punch concrete, but also stir the solution, and screw the bolts. Also, in the technical specifications, you should pay attention to the maximum allowable drill size. For various materials, be it brick or concrete, there are drills that are applicable to a particular material. Plus to all this - the high power of the device itself.
Preferred Power Source
There are two basic types of power sources: battery and mains. When working at height, it is not always possible to connect the power grid. Therefore, in such conditions, it is most effective to use models that run on batteries. The battery itself must have a high capacity, as shock power will require big expense energy. The main feature of these types of punchers is the price indicator. Battery powered devices are much more expensive than mains powered devices.
How to choose a Bosch rotary hammer
Today, many companies selling repair equipment recommend choosing a good hammer drill in favor of the German power tool giant Bosch. She has long been at the hearing of every inhabitant. The main feature of this brand is a reliable and high-quality product. To give advice on choosing a reliable rotary hammer Bosch- you need to understand their labeling. You can find the following designations: PBH or GBH.
- G - device for professional use. R - a device used for domestic use.
- The numbers indicate the weight of the tool. (example: 3-40, 2-32).
- Capital letters: d - applicable for chiselling, f - with a replaceable cartridge, r - has a reverse.
When buying a company's products, carefully read all the technical characteristics of the tool so as not to overpay for unnecessary equipment.
A little about the additional characteristics and weight
The lighter the device, the simpler and easier it is to work with. Many existing household models are lightweight (3.5-4 kg.). Among other additional devices, it is worth highlighting: the possibility of a smooth spin-up of the drill, a rotation speed regulator, and protection against jamming of the drill.
About choosing a drill
Why is idle so important?
The main purpose of the drill is to work with concrete. The difference between a drill and a drill lies in the characteristic tip, produced according to the SDS standard. For various purposes, drills with special nozzles (crowns) are applicable. Each storm is marked with its dimensional characteristics, and on the installation structures, it is indicated which drill (in diameter and length) should be used to drill the required holes.
A tip for choosing a reliable hammer drill is to choose a kit that includes: the device itself, a drill and a case for easy transfer and storage of the tool. It is recommended to give preference to well-known companies that have proven themselves with the best side and their products are of excellent quality.

The best punchers for 5000-6000 rubles
Today in stores selling various kinds tools for household and professional needs, you can find various models of hammers and drills in the parameters of which even the "hardened" owner can get confused.
Consider these questions:
To facilitate the difficult choice among a huge amount of equipment, this review was written.
What is a hammer drill and how is it different from a drill
Drill- mechanical or electric tool, which is designed to give rotation to a special cutting tool for making holes in various materials. About, which drill to choose for home can be read.
Hammer drill- a transitional structure between a drill and a perforator, in which the impact part is implemented due to the mechanical work of the gears.
Perforator- a special mechanism similar in design to a drill, but in addition to rotation cutting tool, due to the pneumatic or electromagnetic component of the tool, the cutting edge is given translational motion.
The main difference between a hammer drill and a drill is that it is extremely difficult for them to make a miniature hole in the right place. Due to the translational moments of motion, the design of the power tool constantly vibrates and it is extremely difficult to get to the right place.
And after the punch is set in the required position with the help of the same mechanical energy, the hole is larger than the drill used. Yes, the tool has a drilling mode, but it is better to use a fully functional drill for this.
What are perforators
In order for the user to choose the right puncher for him, it is necessary to familiarize himself with all their main characteristics.
- Perforator type There are two main types of such instrument. They differ in terms of location. electric motor putting them into action.
AT horizontal type of execution of the device, the engine is located along the axis of the perforator. Such tools are convenient when working in narrow openings and passages, however, they lose in power to vertical ones.
Vertical or as it is also called, the L-shaped rotary hammer has an engine position perpendicular to the drilling axis, as a result of which it is much easier to cool. Compared with horizontal models, vertical, with the same size have significantly higher power and torque.
- Power the selected tool is a minor characteristic of perforators. In fact, the power developed by the electric motor is indicated on the tools themselves or their packaging, it affects how much effort will need to be applied to the tool in order to perform the intended work.
Simply power allows the user to roughly determine the class of equipment offered.
For home , unless, of course, you are going to do repairs professionally, a rotary hammer with a power of up to 600 watts is quite suitable. It will be quite comfortable for them to cut holes or strobes for wiring in.
For professional use it is better to use models of 1-2 kW. This will allow you to easily make holes even in thick monolithic walls.
- impact energy- the main characteristic of any perforator. This feature provides the client general information about the impact force of the tool, which depends on many factors. Such as the mass of the tool, the power of the electric motor, the free travel distance of the chuck. This energy is measured in Joules.
The impact energy of the tool has nothing to do with the force applied to the hammer handle, so it makes little sense to apply a significant amount of force when drilling, otherwise this may lead to tool failure.
The puncher is selected according to the principle - the higher the impact energy, the easier it will be to work with it, and the larger the diameter of the punches can be used in work.
- Chuck rotation speed- is an main feature professional and household punchers. Professional tools have lower speeds due to the fact that when working with a large diameter impact drill, the rotation of the chuck is only necessary to remove debris from the hole.
When rotating at high speeds, as in impact drill, the puncher quickly fails.
If it is necessary to frequently break through wide holes, it is necessary to choose punchers with a lower number of revolutions within 400. If only holes of small diameter are needed, then it will be possible to use a tool with an initial number of revolutions from 1000-1500.
As for the brand of the perforator, it is better to choose an already proven and well-recommended one. Do not be tempted to buy a cheap and unknown Chinese brand.
Type of cartridge used- an important parameter, which determines how expensive the applied expendable materials(drills, punches, cutters) and their maximum diameter. In total, there are three sizes of perforator cartridges:
- SDS plus - used for fastening drills with a shank that has an own diameter of 10 mm and is equipped with four grooves and can be used to fasten drills up to 26 mm in diameter;
- SDS top - for nozzles with a shank diameter of 14 mm, designed for holes 16-25 mm.
- SDS-max – It is used for drills with a diameter of 18 mm, and can drill holes of at least 20 mm;
- ZVP or BZP cartridges - used in non-professional models of rotary hammers and impact drills. Allows the use of standard cylindrical drills.
The last cartridge should only be considered for a light home puncher, if the user does not plan to use it often, otherwise the tool will quickly fail.
Perforator - a tool that allows you to perform drilling work. As a rule, the unit performs rotational-impact movement and longitudinal-axial. The tool can be compared to an impact drill, although they are not exactly the same thing. Let's figure out how to choose a hammer drill for home use. It is worth noting that you do not need to buy a professional device, but it is also not recommended to choose the simplest models.
General information
The perforator allows you to get holes of various depths and diameters. The range of materials in which drilling is performed is quite wide, but almost always these are products with high level strength and rigidity (reinforced concrete products, etc.). Currently, a pneumatic or electric mechanism is used, which provides the shock movement of the drill towards the material being processed, the return is carried out due to the elasticity of the surface being processed. Many people ask about how to choose a hammer drill for the home. This is not as simple as it might seem at first glance. Firstly, a large selection of tools is immediately confusing, and secondly, the units different brands and prices are very similar to each other, so you need to at least understand the basic parameters a little.
Impact drill or hammer drill?
If you do not find what you are looking for in the store, then you will most likely be offered to buy an impact drill. But you need to understand that the puncher is a slightly different unit. First, even with less power, the device can make a hole in a much larger durable material than an impact drill. If you want to get holes without using hammers, then choose a drill, but remember that a hammer drill can also work in hammerless mode as an additional feature. If to speak plain language, then these two tools are very similar to each other and at the same time very different. Drills are more powerful, weigh little, but do not allow you to work with some materials. A modern hammer drill will cost a little less, and its dimensions are not so large. A powerful drill and high speed allow you to make even holes in a short period of time, but some effort will be required. Let's take a closer look at how to choose a hammer drill for your home, as there are a lot of interesting details here.
How to choose the right power
So, it is easy to guess that this parameter is the main one. If you are going to buy a hammer drill, then you need to focus on power. This indicator is measured in Watts. The spread here is quite large: from 450 to 2,000 watts. Today there is no clear classification of perforators by power, but we will try to conditionally divide the tool into two groups. We will refer to household units with a capacity of 450-900 watts, and everything above can be considered professional. Basically, if you plan to use the tool quite infrequently and not get deep holes, then 500-650 watts is enough. If you want to buy a hammer drill for frequent use, for example, to make repairs in an apartment, then buy a unit of 750-900 watts and you will be satisfied. In principle, in everyday life you are unlikely to need a professional tool.
Determine the type of perforator
There are two types of tools according to the location of the engine in the housing: horizontal and vertical. It is easy to guess that in the first case, the engine is located parallel to the shock axis. In the second case, the motor has a perpendicular arrangement relative to the shock axis, they are also called L-shaped. Well, now let's figure out how to choose a hammer drill for working at home according to the location of the engine. If you are going to carry out work in narrow deep openings, then you will definitely fit horizontal arrangement engine. But this solution also has its drawbacks, for example, insufficient engine cooling, as well as low power. These cons are devoid of vertical perforators, therefore, they are more often issued for work in difficult conditions where long uninterrupted runtimes as well as high impact power are required. But since we are choosing a device for the home, pay more attention to horizontal models.
About the force of impact
The efficiency and speed of the device largely depends on its impact capabilities. The amount of energy with which the interaction with the machined surface is carried out directly affects the quality of the hole. As good example Let's compare the two perforators. One of them is Bosch, with a power of 750 watts with an impact force of 2.8 Joules, and the second is Makita with 1,500 watts and 20 Joules. The first hammer drills holes in concrete up to 26 mm in diameter, while the second drills up to 52 mm. One model exclusively for home use, the other is professional. You ask, how to choose the right puncher according to the force of impact? Focus on about 2.6-4.5 Joules. This will be quite enough to make repairs at home. You can get holes with a diameter of up to 30-35 millimeters.
How to choose a hammer drill for concrete
There are several important points here. First, always pay attention to the markings that are made on the mount. To work with concrete, it is necessary to have the designation SDS +, which indicates the versatility of the device. With such a unit, you can screw bolts, mix mortar or drill holes in concrete with an impact method (or non-impact). Secondly, pay attention to power. It has already been said above that this parameter is important, especially when it comes to working with bricks, slabs or reinforced concrete products. In order to get a hole in concrete wall with a diameter of 3 centimeters, you must have a 5.5 Joule puncher with a 10 mm drill. If you plan to double the diameter, then it is not at all necessary to buy a more powerful tool, you can try installing a crown on a stone.
Preferred Power Source
Today on the market are networked and battery models. The first - the most common, have a number of advantages over a perforator on a battery. But it happens that there is no way to bring the power supply. For example, working at heights or in other conditions where there is no electricity. But it is worth paying your attention that the battery capacity must be very large. This is due to the fact that drilling, chiselling and other work requires a lot of energy. Insufficiently capacious battery will sit down pretty quickly. But the main problem is the too high cost of the device. Another option is a pneumatic hammer drill, distinguishing feature which is the absence of a spark during the performance of work. Unfortunately, in our country this is considered exotic, if you see such an instrument, it’s already good, but it’s unlikely that you will be able to buy it. For home use, a mains-operated puncher is best suited.
How to choose a Bosch rotary hammer
All masters, from beginners to professionals, have heard or used Bosch tools. Hammer drills of this manufacturer are best sold, due to the high quality of the product. To do right choice, you need to at least a little deal with the markings indicated on the case. Let's start with the simplest - letter designation. As a rule, this is GBH or PBH. The letter G means that the unit is designed for professional use(frame of blue color), and P says that the punch is suitable for domestic purposes (green body). Numbers can go further: 2-26, 3-38, etc. They indicate the weight of the instrument to the nearest gram. Further on the case there are capital letters. For example, "d" means that there is a chiselling mode, and "r" indicates that the device is equipped with a reverse (reverse stroke). In addition, there may be the letter "f" - a replaceable cartridge. As you understand, the last designations may not be. Do not buy a unit with features that you will not use, this is just a waste of money.
A little about the additional characteristics and weight
Do not forget that the mass of the device plays a big role. The lighter the device, the easier it is to work with. Naturally, light weight is typical for low-power rotary hammers, and this should not be forgotten. A light tool can be considered a tool weighing up to 3 kilograms, and everything above belongs to the medium (3-5) and heavy (5-12) categories. For domestic purposes, a unit with a total mass of not more than 3.5 kilograms is quite enough. Concerning additional features, then it is desirable to have a speed controller. This will allow you to speed up or slow down the work of the drill directly during drilling. It is desirable that there be a soft start function that eliminates jerks during the first start-up of the equipment. You can also look at the tool, which is equipped with a mechanism to protect against jamming of the drill. A special clutch is installed that will protect not only the engine, but also the worker. You already know how to choose good puncher, and if all of the above functions are present, then this is an ideal solution for use in everyday life.
About choosing a drill
As you understand, a drill is necessary for working with concrete structures. The main difference from the drill is the shank, which is made according to the SDS standard. If you need to do big hole under the outlet, you will need special crowns. They are divided into several types: diamond and for dry drilling. The former are more expensive, so for domestic use the second option will do. It is worth noting that choosing a drill for a perforator is quite simple, you just need to pay attention to a few details. Firstly, the steeper the spiral, the higher the characteristics (speed and depth), and secondly, buy only original drills. This is due to the fact that the shank of a copy made in an unknown place will not always fit your puncher, especially when it comes to models such as Bosch, Makita, etc. In principle, this information should be quite enough in order not to make a mistake with the choice. Remember, a quality drill costs a lot.
Why is idle so important?
One should not lose sight of such an important indicator as the number of revolutions x.x. It is best if there is a special knob that allows you to adjust the idle speed. In this case, you can customize the drill and drill for the specifics of the work performed. For example, to work with a foam block, fewer revolutions are needed than when drilling concrete. By the way, high speed is also not always good. This is due to the fact that at extreme speeds, the drill heats up much faster and can fail much faster. To avoid confusion when doing various works, change the fastening systems, then everything will be in order.
Regardless of whether it's a professional tool or not, buy one that comes with a drill, drill and a case where you can carry the device. Today, the budget segment has a fairly extensive selection. There is noteworthy models, for example "Zenith" ZP-1100. Such a device will cost you about 2,000 rubles. Comes with an SDS+ class chuck suitable for medium sized drills. Another one interesting model- "Bosch" PBH 2100 RE. For such a tool you will have to pay about 4,000 rubles. This unit has an impact force of only 1.7 Joules, so it can be classified as low-power. However, for home use it is perfect solution. If you do not know which company to choose a puncher, then give preference famous brand, even if you overpay 5-10% for the name, but you will use it for a long time and without problems.
Conclusion
Well, here we are with you and figured out how to choose a drill with a hammer drill. Now you should not have any problems when buying. Never buy a used tool, as it makes little sense at all. It is better to buy something inexpensive, but new. You will receive a guarantee, which you can use at any time. If you are mostly going to work with concrete, then definitely buy a hammer drill, believe me, the difference will be noticeable and far from in favor of an impact drill. If prices in your stores are too high, pay attention to the range of goods on the network, of course, if you trust such purchases. That's all that could be said on this issue. As you can see, not everything is as complicated as it might seem. Take some time to consider the basic parameters, and you will definitely make the right purchase.
