The puncher is a construction tool whose main purpose is to punch holes. This causes some confusion. It often happens that a
percussion drill is called a “perforator”. By definition, in principle, everything is correct, but in reality it turns out that there is still a difference. In work, the drill relies heavily on rotation. A rotary hammer, on the contrary, strikes its way with blows. Rotation only takes away the spent material and helps it in forming the hole.
