Replaceable Tip System for Cutting Devices

Abstract

A replaceable tip system for cutting devices includes a cutting element, an adapter, a base, and a wedge. The cutting element includes a tip and a shaft extending from the tip. The adapter includes a channel extending through the adapter. The base is coupled to a driven cutting piece. The wedge extends from the base. The wedge is insertable into the channel to urge the shaft into frictional engagement with the adapter and thereby secure the cutting element to the adapter to prevent disengagement of the cutting element from the adapter and the base. The cutting element, the adapter, and the wedge are designed and positioned such that forces generated during a cutting operation on the cutting element bias the cutting element and the adapter toward the wedge and thereby enhance the frictional engagement.
