Basic parameters for choosing a punch
Maximum impact energy
This is one of the main characteristics for choosing a rock drill. Indicates how hard the drill or chisel will hit the material. The higher the value, the faster the hole will be drilled. Devices with an impact energy of up to 3 J are considered household devices. This is quite enough to make a hole for a dowel or a strobe for laying electrical wiring. powerful devices are professional.
In household rock drills, the power usually varies between 600-800 W, in powerful professional ones. up to 1.5 kW and above. With the same impact force, the rotational speed of the drill and, accordingly, the performance of the device will depend on the power.
Maximum number of strokes
This figure is not critical for hammer drilling or chiselling. But if the hammer drill is planned to be used as a drill, then it is worth noting that for normal drilling of metal, at least 1200 rpm is required. To insert the drill, you first need to install the cam parton. It often makes no sense to use an adapter with an SDS shank, since these types of fasteners have significant backlash, which will negatively affect the quality of drilling.
Drill mount type
SDS-Plus. Shank diameter 10 mm. Suitable for drills up to 30 mm in diameter, drill bits and chisels. Fits in small and medium rotary hammers.
SDS-Max. The 18 mm clamping diameter allows you to work with long large diameter drills, larger bits, as well as flat chisels. Installed in powerful rotary hammers.
Maximum drilling diameter
Manufacturers indicate limits for drilling in concrete, metal and wood. It is important to understand that drilling deep holes at maximum values is fraught with rapid wear of the hammer drill.
Chiseling. this mode allows you to cut through walls, make a strobe, in general, any activity in which you do not need to apply rotation. Do not try to make a hole in this way, as this will most likely lead to jamming of the drill.
Drilling. this is when the drill just rotates, without blows. In bricks, porous blocks, wood concrete and cinder blocks, only drilling can make an even hole. In other cases, it is worth taking a closer look at models with a replaceable cartridge.
Drilling with a blow. the main mode for most household rotary hammers. Allows drilling holes in concrete, porcelain stoneware, stone.
Rotary hammers for home
We have selected several household rotary hammers based on the selection of our customers.
Rotary hammer DH-750C FIT 80119
The vertical rotary hammer is chosen for simple household chores. Drill mounting type. SDS-Plus. The power is 750 W, the maximum impact energy is 2.8 J, the number of blows per minute is 3900. With it you can effortlessly hang a shelf for books or a TV stand. A hammer drill is also able to drill wood or remove the remnants of old tiles by chiselling with a chisel. Easy to drill with additional handle and depth gauge.
Perforator Zubr ZP-32-1100 K
This powerful domestic horizontal rock drill can handle just about any job. Drill mounting type. SDS-Plus. Power 1100 W, maximum impact energy 3.5 J, 5100 beats per minute. With it, you will be able to hang a shelf or beat off an old finish, put cornices or expand a doorway. The safety clutch will protect from damage if the drill gets jammed, and the reverse will help to get it. To make your hands less tired of vibration loads, there is an anti-vibration system. In the case there is a removable handle with a depth gauge.
Perforator Zubr P-22-650
This inexpensive rotary hammer with a longitudinal engine is taken mainly for housework. Drill mounting type. SDS-Plus. Power 650 W, maximum impact energy 2.3 J, impact frequency per minute. 4850. This is enough to drill a hole in the wall for a dowel or anchor bolt, and hang a picture or kitchen cabinets. The hammer drill can drill, chisel or drill with a blow, so it often replaces a drill. If the drill jams, the safety clutch will prevent the tool from escaping from the hands, and the reverse will help pull the drill out of the hole. In the case, in addition to the perforator itself, there is also an additional handle with a depth gauge.
What to consider when choosing a hammer drill
This tool can be: with one drilling mode, with two modes (drilling plus hammering), as well as with three modes (chiselling is added to the previous two modes). In addition, rock drills are classified by weight into heavy, medium and light. The latter will not be heavier than 4 kilograms, the average will “pull” from 4 to 5 kilograms, and the heaviest devices of this type can weigh 5-10 kilograms or more.
The following functions can be built into the hammer drill:
- Drill depth gauge helps you know if the drill has reached the correct mark.
- The gearshift mechanism comes in handy when you need to switch from drill to drill or vice versa. Because they have to move at different speeds.
- Reverse rotation of the shaft will help out when the drill gets stuck in any surface.
- A soft start and a device that protects against overheating will help to avoid troubles that promise a breakdown of the device.
- Stabilization of the shaft speed during fluctuations in the load force is a very useful function.
Rotary hammer shape
In terms of shape, perforators are both straight and L-shaped. In the latter, the motor is located vertically, making the device more compact. In addition, the engine is cooled efficiently. Such devices can work for a long time without overheating, and they serve a lot. But their weight is very noticeable.
L. Rotary Hammer, Vertical Motor.
Narrow and long straight type perforators weigh less, and due to their design, they will crawl into any gap. The engine is placed horizontally in them.
Narrow, long rock drill, engine horizontal.
So, for example, protection from dust does not hurt at all. after all, hardly anyone has to work in sterile conditions.

Dust protection during drilling.
No less convenient is the anti-vibration system, which softens and compensates for the shaking of the device when drilling, chiselling or drilling.
Vibration protection system.
Another useful “trick” is the locking button that secures the punch in working mode.
True, each of the additional features does not make the device cheaper at all, so choose only what you really need. It is not worth it, really, to overpay for those functions that you will never use in the future.
Impact energy is one of the main parameters of the device. Joules are used to measure it. Lightweight models have an impact force of no more than 1–2 joules, while “heavier” punches can hit with a force of 8 to 15 joules. The greater the impact energy, the larger the hole diameter can be obtained. When this value is small enough, the device does not work more efficiently than an impact drill. In this case, he will not punch a hole, but drill it. As a result, its equipment will wear out extremely quickly, and you will not have to dream of high performance.
You should be aware that a value of this parameter exceeding 10 joules will lead to rapid failure of your instrument. Indeed, under such high loads, its refractory inserts will collapse in a very short period of time.
If you need a hammer drill for drilling small holes for dowels and anchor bolts, then see compact models of devices with an impact energy of 1.2 J:
If, in addition to drilling holes for a dowel, it is necessary to perform: chipping, cutting out socket boxes, drilling large-diameter holes, choose medium-power devices with an impact energy of 5.8 J:
If a hammer drill is necessary for dismantling walls and punching passages, then look at powerful devices with the SDS MAX system and an impact energy of 10 J or more:
The rotational speed of the punch shaft is lower than that of the drill. this has already been mentioned above. Depending on the class of the device, the value of this value can be from 600 to 1500 rpm. The rotational speed decreases with increasing power and productivity of the rock drill. this is due to its design features. Indeed, for productive models, the optimal tooling diameter is quite large. In general, the shaft of the device rotates only in order to remove dust after drilling. A small drill has to rotate faster, and a large one. slower, otherwise it will wear out too quickly.
Models of rock drills with high shaft rotation speed are heavy, which does not facilitate ease of use. In addition, such high-speed devices wear out the spiral grooves very quickly, with the help of which the drilling waste is removed from the place of work. Because of this, the device begins to heat up quite a lot, and as a result, it can even jam in the hole.
Hammer Drills. When and What to use
If we calculate how many times in one minute the piston of the device strikes against its firing pin, we get a value called the frequency of strikes. The larger it is, the higher the hole punching speed. The performance of a rock drill depends on both the frequency and the energy of the impact. The manufacturers that produce the most durable and efficient devices in their models harmoniously combine these two parameters.
Therefore, it is better to pay attention to reliable brands, whose products are of excellent quality and amazing durability. Specifically, we will talk about the best manufacturing companies a little further.
The main characteristics and functions of the punch
Perforator. a device equipped with a percussion mechanism. It is designed for drilling holes in hard materials such as concrete, brick wall, metal.
The main characteristics of this device are several.
- Impact energy (J). The diameter of the holes that the tool can drill depends on this characteristic. For household needs, it is better to take a device with parameters up to 2 J.
- Spindle rotation speed (revolutions / minute). On average, this figure is 500 1500, but sometimes 4000 5000 rpm.
- Impact rate or number of piston strokes per minute. The drilling speed depends on this characteristic.
The weight of the tool directly depends on its power. According to this indicator, performers are divided into:
- lungs. up to 3 kg, power up to 800 W, impact energy up to 3 J;
- average. up to 5 kg, power up to 1000 W, impact energy 3. 10 J;
- heavy. more than 5 kg, power more than 1000 W, impact energy from 10.30 J.
For a home, a good choice of a hammer drill would be a light model, since its characteristics are enough for household needs. Such a tool will be optimal in terms of price, weight and dimensions. If you have more complex work ahead of you, then you can choose the average weight of the device.
How to choose a hammer drill for home
Review of hammer drills for home. what to look for
The key difference between household and industrial tools is the uptime. The home punch needs a break due to the lack of overheating protection. 20 minutes of work should be followed by 20 minutes of rest. This does not mean that a household tool has a simple structure. What kind of hammer drill is chosen for homework? This is a tool that has lightness, compactness, versatility, affordability, design reliability and electronic filling.
Generally, home rotary hammers have a horizontal motor and SDS Plus chuck. This design provides compactness and ease of use.
Depending on the number of modes, the devices are divided into:
- single-mode, which can only drill;
- drilling with and without impact is available to dual-mode devices. Make holes in brick and concrete walls up to 1 cm thick;
- three-mode. the most demanded. In addition to the previous ones, the chiseling function is available to them. Such a device can be grooved and dismantled, but only in small volumes.
The BOSCH brand is represented by 9 items of tools. A good choice for home use. perforators with a capacity of 650.800 W and weighing up to 3 kg. Perforators from the German manufacturer are equipped with a safety clutch, rotation and impact blockers, a rotary brush holder, a hinged cable mount, soft pads for handles, and a convenient chuck. They are compact, lightweight, reliable and powerful.
