And already in 1932, electric perforators were born, the popularity of which has survived to this day. They are widely used both in everyday life and for industrial purposes. With their help, various repair and construction work is carried out.
As a drilling machine, the hammer drill provides, along with a rotary movement (drilling), and also provides a reciprocating movement.
Basic types
When choosing a punch, you must definitely take into account its type, because among the huge set of these devices there are options that perform certain functions, which in one case may be suitable, but in the other not.
Depending on the drilling mode, the following types of hammer drills are distinguished:
- single-mode (drilling);
- double-mode (drilling plus impact);
-
three-mode (drilling, impact, chiselling without rotation).
- electrical network - the most common, can be used for almost any work;
- electric rechargeable batteries - they are convenient during facade work;
