Patent ID: 8757299

Claim:
A cutting element for use in a drilling bit and/or milling bit comprising: a cutter body comprising: a substrate having an upper surface; and a superabrasive layer overlying the upper surface of the substrate, the superabrasive layer comprising an upper surface extending transversely to a longitudinal axis of the cutter body, a rear surface opposite the upper surface, a side surface extending between the upper surface and the rear surface, and a chamfered surface extending at an angle to the longitudinal axis of the cutter body between the upper surface and the side surface; and a sleeve extending entirely circumferentially around and directly contacting a side surface of the superabrasive layer and a side surface of the substrate, wherein the sleeve exerts a radially compressive force on the superabrasive layer; and a layer of material having a Mohs hardness that is less than a Mohs hardness of the superabrasive layer disposed between the chamfered surface and the sleeve.
