ABSTRACT:
A punch and retainer assembly wherein the punch has a non-circular punching end, a flattened surface at the upper end of the side wall thereof and a radially inwardly extending recess directly below the flattened side wall portion. The punch retainer includes a vertically movable latch adapted to engage within the recess on the shank of the punch and retain the punch within the retainer. Means are provided for limiting vertical movement of the latch so that the punch can be inserted into the retainer only when the flattened surface thereof is aligned parallel with the pivot axis of the punch. Spring means are also provided for maintaining the non-circular punching end of the punch in a predetermined circumferential angular relationship relative to the latch.
