The punching part has a punching cutting edge that limits a punching cutting area, the punching part being intended to pierce the workpiece. The broaching part is intended to tear the workpiece later than the punching part, and includes at least a broaching tooth with a cutting edge that limits a cutting area which is greater than the punching cutting area.
