ABSTRACT:
A punch assembly to which a tool piece is easily attached and removed. A punch body is provided at its lower end with a fixed locking element having a tool receiving basin. The annular wall defining the basin has one or more holes through it and an annular, downwardly facing rim. A bearing is positioned within each hole for movement between a locked position and a released position. A moveable locking element having an interior surface with at least one recess alignable with the hole(s) and at least one platform also alignable with the hole(s) is slidably positioned with respect to the outer surface of the side wall for movement between a released position and a locked position. The moveable locking element is in the released position when the recess(es) are aligned with the hole(s) so that the bearing(s) may be at least partially received within the recess(es) to enable the tool piece to be removed from the basin. The tool piece may have a frustoconical portion received in the basin and held in the basin when the bearings are held in their locked positions.
