Abstract:
One embodiment relates to a workpiece removal device for a plug cutter. This combination comprises a housing having a longitudinally extending surface, a first closed end and a second open end opposite the first closed end. A boss is coupled (removably coupled for example) to the first closed end and extends toward the second open end, and a biasing member (a spring for example) is attached to a distal end of the boss. The combination further comprises means for contacting a predetermined portion of the biasing member with a workpiece, whereby a preselected portion of the workpiece is ultimately severed from the workpiece. The biasing member ejects the preselected portion from the plug cutter, forming a plug.
