A multiple punch and die assembly body member has dies or strippers that are held within multiple pockets in a multipunch body member by means of a centrally positioned retaining member formed from a rigid or flexible material located in a central recess at the middle of a ring of the surrounding dies or strippers. The retaining member is preferably held in place by a push plate that can be secured to the multipunch body member by a tightening element, e.g., a screw fastener for pressing the peripheral surface of the retainer member into engagement with the dies or strippers to hold them in their respective pockets in the multipunch body member.

A punch assembly for a hydraulic punch press machine that affords the ability to compensate for punch point metal loss due to resharpening by facilitating accurate repositioning of the punch point relative to an aperture in a stripper plate through which the punch point member projects during a stamping stroke of the punch assembly.
