ABSTRACT:
A punch holder is detachably connected to the lower end of a vertically reciprocable ram and carries a plurality of differently shaped punches which are supported to slide upwardly and downwardly in the holder. Individual actuators are operably associated with the punches and selectively activate one or more punches during any given punching stroke of the ram so that either one hole or multiple holes may be punched during such stroke.
