This is an automatic punch used to produce a dimple in a part. It performs the same function as a normal centering punch, but without the need for a hammer. When pressed against the workpiece, it stores energy in a spring, then releases it as an impulse which moves the punch, producing the dimple. The pulse supplied to the punch is quite repeatable, which allows uniform engravings.
