More Information
Summary:A superhard polycrystalline construction has a body of polycrystalline superhard material having a cutting face and a substrate bonded to the body of polycrystalline superhard material along an interface. The substrate has a substrate body and a first end surface forming the interface, the first end surface of the substrate having a projection extending from the body of the substrate into the body of superhard material towards the cutting face. The projection has an outer peripheral surface around which the body of polycrystalline superhard material extends. The body of polycrystalline superhard material has a thickness from the cutting face along the peripheral side edge to the interface with the substrate of at least around 4 mm and at least a portion of the projection has a thickness measured in a plane extending along the longitudinal axis of the construction of at least around 4 mm.
