The review is based on the analysis of the technical characteristics of rock drills on the rankquality analytical portal.

Rating of the best professional rock drills

The experts of our magazine, when compiling the TOP-6 professional punchers, took into account key characteristics, such as:

1. Power, W);
2. impact energy (J);
3. the number of revolutions and strikes made;
4. ergonomics of the model;
5. endurance.

We also focused on the opinion of professional builders in the reviews, which helped to highlight not only the pros, but also the cons of the product.

Milwaukee Kango 950 S

Rating: 4.9

The review was led by a rotary hammer from the Milwaukee brand with a power of 1700 W and an impact force of 27 J. The professional model has a D-shaped handle with a rubberized pad on one side. The second D-type handle rotates 360º on the gearbox. The manufacturer has taken care of a third I-handle that can be threaded into the gear housing or next to the main handle, converting the rock drill into a T-bar for drilling in the low position. In the reviews, the owners like that the kit contains a large tube of grease, which is enough for a couple of months of active work. The hammer drill also has a carbon brush shut-off system that does not allow starting with worn out graphite elements.

Our experts, after studying the reviews of the masters, concluded that this is the most “indestructible” perforator that will withstand any harsh operating conditions. It can withstand drops from a height of 1 m, overheating, temporary operation without lubrication and an ambient temperature of -20 ° C.

Advantages

• 1950 blows in 60 seconds;
• metal gearbox;
• two modes of operation;
• rotation of the chuck up to 250 rpm.

disadvantages

• hands get very tired from the weight of 11.8 kg

Metabo KHE 96

Rating: 4.8

The second place was taken by a professional-grade perforator from the German corporation Metabo. The model is very similar to the one described above in configuration and is its direct competitor. The Germans endowed a hammer drill with a similar power of 1700 W, two modes of operation, a frost-resistant wire and the ability to rotate a rig in the range of 125-250 rpm. The master can adjust this indicator independently, depending on the hardness of the material being punched. But the impact force here is slightly inferior to the competitor and is 20 J versus 27.

We rated the professional product as the best due to its soft start, which helps to get started without jerking. If the tool is used all day, it significantly reduces the load. Also, judging by the reviews, this model is really capable of drilling a hole with a diameter of 150 mm in concrete with a crown. This ability is worth paying attention to those who install exhaust ventilation ducts, laying them in walls 400-500 mm thick.

Advantages

• rotation of the second handle by 360º with the possibility of changing the angle of inclination;
• wide stop for the second handle;
• for some, it serves up to 7 years with regular workload;
• all elements in the gearbox are made of metal.

disadvantages

• there is no reverse for removing the equipment.
• weak anti-vibration system.

Graphite 58G878

Rating: 4.7

The third place was unanimously taken by a hammer drill from the Polish brand “Graphite”, with a power of 1700 W and an impact force of 27 J. The professional model is supplied in a plastic case that simplifies transportation and storage of the device. The body length of the model is 730 mm and, in order to keep it with optimal weight distribution, there are two additional handles at the end and in the middle of the gearbox. The second can be repositioned next to the main handle to give the shape of a jackhammer. The chuck pushes the drill with an impact rate of 960-1950 per minute, which makes it easy to crush stone, brick and cement screed.

A professional concrete breaker is distinguished by reduced vibration, which is confirmed by the masters in the reviews. The manufacturer managed to implement an effective system that dampens vibrations going to the handle. The price of the hammer drill compares favorably with other products in this category on the market.

Advantages

• cable 3 m;
• metal gearbox;
• one of the most affordable prices;
• easy one-touch snap replacement;
• excellent anti-vibration system.

disadvantages

• overheats when work is being done on reinforced concrete;
• not the most durable gearbox (one of the modes disappears if you switch frequently).

AEG PN 11 E

Rating: 4.6

Here is another worthy professional device with vibration protection and an impact force of 27 J. In addition to the main handle, there is an anti-vibration system even in the screw-in handle. The hammer drill is assembled in the Czech Republic and is endowed with a power of 1700 watts. You can reach the RPM switch with your index finger, adjusting the rotation from 125 to 250 per minute. The percussion mechanism makes shocks in the amount of 975-1950. The model weighs 11.8 kg. The mode switch is located at the top of the gearbox and can be reached with the other hand. The safety clutch will prevent the powerful motor from twisting your hands if the drill gets stuck in the wall.

The professional tool is notable for a long 6 m network cable. This simplifies operation and allows in most cases to do without carrying. The perforator also has a quick change system for brushes. If the graphite elements suddenly wear off, the installation of new ones will take 2 minutes, and not 1 hour, as with others, in the event of a complete disassembly of the case.

Advantages

• I-handle equipped with a damper;
• the cartridge is equipped with a rubber boot;
• effective heat dissipation from the gearbox;
• fuse against unauthorized starting.

disadvantages

• works with a volume of 111 dB;
• there is no auto shutdown when overheating.

BOSCH GBH 12-52 DV

Rating: 4.5

The next model also has an electric motor power of 1700 W, but loses to those described above in terms of impact force – here this figure is 19 J. But the impact system is much faster than that of competitors – 1750-2150 beats / min. The hammer drill is equipped with a 3 m mains cable. The equipment can be untwisted up to 220 rpm. According to reviews, craftsmen like a professional tool with a stable barrel with a motor, which allows them to quickly free their hands by placing the puncher on the table or floor. The rubber pad on the bottom of the barrel is not subject to scratches and protects the plastic from damage. The manufacturer claims that the tool can be used with drills up to 80 mm in diameter.

The hammer drill attracted the attention of experts with its compactness with a body length of 60 cm. In other professional counterparts, this parameter is 70-71 cm. Such a hammer drill is useful for working in confined spaces.

Advantages

• you can quickly put on the “barrel”, freeing your hands;
• additional handle with a wide stop;
• impact frequency 1750-2150 per minute;
• equipped with a safety clutch.

disadvantages

• the body is completely plastic;
• the cartridge does not have a protective boot;
• it is inconvenient to hold in the operating mode of the jackhammer (in the lower position);
• it gets very hot.

CALIBER EP-2000 / 50M

Rating: 4.4

The review concludes with a professional tool from the Caliber brand, which operates in the mode of chiselling and hammer drilling. The front of the cartridge is equipped with ample perforation to provide efficient air cooling. The model is comfortable to hold thanks to the rubberized anti-vibration handle. The start key is locked, making it easier to fix during prolonged manipulations. When the rig is jammed, the ratchet clutch is triggered. In the reviews, the masters like that a pike and a drill, as well as a plastic case, are supplied with the perforator. When concrete partitions with a section of 80 mm collapse, the tool passes the material without the slightest resistance.

The professional device is distinguished by the impact frequency of 2300 beats / min. Combined with a 2000 W electric motor and 25 Joule impact force, this makes the model one of the highest performing models. But the 17.5 kg weight requires more frequent work stoppages in order to rest the hands.

Advantages

• good equipment;
• rubberized handle;
• improved air cooling;
• anti-vibration system;
• the second handle rotates 360º and can be tilted.

disadvantages

• perforator outside completely made of plastic;
• weight 17.5 kg;
• the handle turns tight.
