ABSTRACT:
A two piece punch is provided for use in a punch assembly. The punch includes a generally disc shaped cutter and a cylindrically shaped nut. The punch is assembled by passing a portion of the nut through an aperture in the cutter. The punch is mounted to the remainder of the punch assembly by fastening the nut to the draw stud. As the punch becomes worn, use of the nut continues while the cutter is removed and replaced.
