Punching tool comprises a punch (12) positioned in an adjusting ring (20). The adjusting ring is positioned at a specified angle in a tool holder using a block (24). The angle between the punch and the adjusting ring is defined by an interlocking locking piston. The locking piston is positioned on the block on the side of the adjusting ring so that it interlocks in the direction of rotation. An Independent claim is also included for a block for a punching tool which sits in a radial groove of an adjusting ring and has an opening (36) for holding a securing element so that it cannot rotate. Preferred Features: A pin (32) sitting in a hole (30) in the punch forms part of the locking piston. |
