ABSTRACT:
A polygonal insert of hard cutting material used in single and multiple toolholding means to receive the same, the insert comprising a wafer having conjunctive side walls lying in planes intersecting each other and parallel to the axis of the insert, one or more faces of the insert normal to the sides being depressed to form a peripheral ridge around the insert composed of a cutting land, either negative or positive, and downwardly extending walls to provide a polygonal recess on the face of the insert. A chip breaker insert with the same configuration as the basic insert with smaller lateral dimensions is provided to position selectively within the peripheral walls of the ridge to be clamped in place as a chip breaker. Also, a support anvil is utilized below the insert supporting the face within the ridge walls on the base of the recess in the cutting holder.
