PUNCH ASSEMBLIES AND UNIVERSAL PUNCH THEREFOR

摘要

A punch tip (16) design configured to be universal in its application with wide varieties of punch assemblies, and various punch body (14) designs from which universal application of the punch tip (16) is exemplified. Ancillary components (34, 16, 50) used with the various punch body (14) designs enhance ease by which the operator can selectively manipulate the same for alternately securing or releasing the punch tip (16).
