Puncher is a construction tool, the main purpose of which is punching holes. This creates some confusion. It often happens that an impact drill is called a "hammer drill". By definition, in principle, everything is correct, but in reality it turns out that there is still a difference. The drill mainly relies on rotation to work. The perforator, on the contrary, punches its way with blows. Rotation only removes the waste material and helps it in forming the hole.
