Abstract: A multi-tool adaptor which enhances overall performance of the multi-tools on which the adaptor is intended and the punch presses with which the multi-tools are desired to interface. The intermediary components relating to the functioning of the multi-tool involve one area of consideration regarding the adaptor design. Another area of consideration for the adaptor design involves the manner by which the stripper plate is operably coupled to the punch holder.

Abstract: A punch press has a punching tool assembly removably coupled to the ram, and it carries a plurality of punching pins which are individually selectable for a punching operation. A rotatable cam moves the selected punch pin from a retracted position in the tool assembly to an operative punching position, and the cam is driven by a retractable drive mechanism which is movable into engagement with the rotatable cam to effect such rotation and retracted to an inoperative position, by a moving means. Control means is provided to effect operation of the moving means and of the drive mechanism, and is operable to effect precise rotation of the cam member.
