When choosing a device for the home, it is worth deciding what kind of work it will be used for most often.

In addition to lightness, you need to choose the impact force of the puncher. It is indicated in joules and indicates to the purchaser exactly how the instrument can be used. For example, for simple work at home, an impact force in the range from 1.5 to 3 J.

Also, the selection criteria are the rotation speed of the chuck and the impact frequency. The higher their values, the better quality holes will be made.

The location of the electric motor can also affect the choice of the model of the rock drill. Instruments in which the motor is positioned horizontally are better balanced in terms of weight. Due to this, these models are more convenient to work with.

As additional functions that make it easier to work with the tool, several points are highlighted:

• protection of the electric motor from overheating due to the safety clutch;
• anti-vibration system, which softens and compensates for the shaking of the device during its operation;
• the presence of a reverse (reverse rotation function);
• the ability to adjust the rotation speed of the cartridge;
• brush wear indicator in the rotary hammer motor;
• drilling depth limiter (allows you to understand to what mark the drill has reached);
• speed switching, useful when switching from one mode to another (for example, from drilling to chiseling mode).

Lightweight models have a power rating of 500 to 800 watts.The weight of such products, as a rule, varies from 1.8 to 3 kilograms. They can make holes of about 3 cm in concrete. These tools can be used to cut walls and floors. Exactly Bort lightweight rock drills are the most frequently bought by consumers... Therefore, in the brand's product line, most devices are presented in this category.

The advantages of the device are the presence of a button for locking the operating mode. Due to it, you can be sure that the device does not switch to another mode during use. Another advantage of the hammer drill is its lightness - the weight is about 3 kilograms.

Among the disadvantages, users note the short cord of the product, which is why they often have to use an extension cord. Also among the disadvantages are the rapid heating of the device and long cooling, which is not very convenient when working with the tool.

In the segment of lightweight rock drills, there are also cheaper options, for example, models BHD-700-P, DRH-620N-K... Their cost is about 4 thousand rubles. These tools are not in great demand, primarily due to their low power (up to 800 W). At the same time, buyers note that these are quite good rotary hammers in their price segment, suitable for home use.

Medium hammer drills weigh from 3.2 to 6 kg. They have a power rating of 800 to 1200 watts. The stated hole diameter, which can be drilled with their help, is more than 30 mm. These models are more suitable for working with particularly hard materials.
