Abstract

A multitool punch holder in which a tool carrier (22) holds a circumferential array of punches (76) in a corresponding series of bores. Each punch (76) is attached to a stem rod (50) having an upper end protruding above the tool carrier (22). The tool carrier (22) is rotated by an index drive (102,104, 106, 108) so as to bring a selected one fo the stem rods (50) beneath a ram drive feature (100) protruding radially outward to lie above of the stem rod ends (52). The tool carrier (22) is coupled to the ram (14) by a head member (20) which is telescopically received therein allowing the ram (14) to continue its descent after contact of the tool carrier.
(22) with the workpiece, the ram (14) having a feature (100) engaging a selected stem rod end (52) lying beneath the ram drive feature (100) to cause advance of the attached punch (76) against the resistance of an encircling stripper spring (62).
