Abstract
The adapter member includes a threaded male portion adapted for threadable engagement in a threaded bore of the punch and a threaded female portion of smaller diameter adapted for threadable engagement with a small diameter threaded end of the draw stud which can pass through an initial small diameter pilot hole in the workpiece. The adapter member allows the punch to accommodate a draw stud of sufficiently small diameter to fit through the pilot hole and allows punching of a larger diameter hole in light gage or non-ferrous materials without enlarging the pilot hole. This arrangement eliminated the need in the past for the additional step of enlarging the pilot hole to accept a draw stud of larger diameter that was threaded directly into the thread bore of the punch for punching larger diameter holes in both heavy and light gage material.
