ABSTRACT:
The invention concerns a tool for stamping of holes or the like in sheet material, such as metal plate. The tool is mountable on a handheld motor, such as a pneumatic or hydraulic piston and cylinder motor and comprises a stationary part supported against the motor cylinder and a movable part connectable to the motor piston. The displaceable tool part has at least one slot at right angles to the direction of the motor stroke and a through drilling extends through said slot at right angles thereto at a distance from its base. The portion of said drilling at the outside of the slot is formed as a stamping die, and the portion thereof inside of the slot accommodates a stamping plunger, whose inside end engages the stationary tool part. When a piece of sheet material is inserted into the slot with its edge in engagement with the base thereof and the motor is actuated, the plunger stamps a hole in said sheet material at a fixed distance from its edge. One embodiment of the device provides a slot for deforming sheet material on one side of the tool opposite the slot for stamping.
