A drill is an extremely useful and versatile tool, but often its capabilities are insufficient. This is especially noticeable when working with stone and hard concrete: sometimes it is simply not possible to take them with conventional drilling. And then impact drills come to the rescue. Why are they good, how to choose them and what 5 impact drills deserve the title of the best, we will now tell you.

What characteristics to look for when choosing a hammer drill?
Type of food. Impact drills can be powered from the mains, battery or compressor. Pneumatic drills are the lot of professionals only, although in terms of productivity and usability they can leave competitors far behind. Mains electric drills are the most popular devices of the type in question: they are productive and versatile, but tightly tied to the outlet. Cordless drills, in turn, usually do not know as much as pneumatic and network counterparts, but they do not need life support system in the form of an outlet or compressor, and mobility allows them to forgive any limitations.
Power. The main characteristic of network impact drills, which allows you to roughly judge their performance. Typically 400 to 1500 watts. For domestic needs, 600-700 W is enough, and in the professional field, more powerful tools are preferred. For pneumatic drills, this characteristic is replaced by the power of the compressor, and for rechargeable drills - the battery voltage, which can be from 12 to 24 volts.
Torque. Determines how hard the materials are on the teeth of the drill. It is measured in Newton meters. The higher the torque, the better.
Maximum drilling diameter. The more powerful the drill and the higher its torque, the larger holes it can make in various materials. Drilling diameters in wood, concrete and metal are usually indicated.
Rotational speed. Measured in revolutions per minute. The more of them, the, as a rule, the better, because this speeds up the work of the drill, especially with materials to which the impact mode is not applicable.
Number of speeds. Simple tools usually only have one speed. More expensive impact drills are equipped with two-speed gearboxes, which allow you to lower the rpm in order to increase the torque. This low gear makes it easier to handle difficult materials.
The maximum number of beats per minute. The hammer drill works very quickly: the number of blows can reach 40,000 per minute or more. This partly compensates for the low energy and small amplitude of the shocks.
Chuck type. Impact drills are equipped with two types of chucks: key and clamping. The former are more reliable, but require a special key to change the equipment. And the key, as usual, is constantly lost and wastes a lot of time. The latter allow you to change drills with your bare hands and in a matter of seconds, but the reliability of the fastening directly depends on the firmness of the user's hands.
Chuck diameter. Shows which drill size the drill supports. Usually adjustable from 1.5 to 16 mm.
Options. Impact drills do more than just drill. They are equipped with reverse functions for unlocking jammed drills or working as a screwdriver, illumination of the working area, blocking of the power button, various protection systems and other additional functions.

FAQ
What is the fundamental difference between a hammer drill and a hammer drill?
A hammer drill and an impact drill are similar tools, but they are constructed differently. The main thing that a puncher can do is reciprocating movements, and he copes with them perfectly. He makes blows with the help of a pneumatic mechanism, and their energy is very high, so drilling for a hammer drill can only be called an additional, but not the main function. The hammer drill is geared precisely to rotate the drill. The percussion mechanism of such a drill is a pair of ratchets that provide fast, but weak impacts with a small amplitude. Therefore, in terms of the efficiency of working with concrete and stone, an impact drill is seriously inferior to a hammer drill. But it wins in price, weight, size and versatility, so it can be called a better choice for home use, and a hammer drill - for professional use.
Can a hammer drill be used to drill iron?
It is possible, but only with a special drill for metal and in a non-shock mode. Otherwise, there will be a mockery of the drill, and of the drill, and of oneself.
What's the best to use on wood and concrete - an impact drill or hammer drill?
For wood - a drill in drilling mode, for concrete - a perforator, its performance is, nevertheless, much higher than that of a drill.
