摘要： A superhard polycrystalline construction (1) comprises a body (12) of polycrystalline superhard material having a cutting face (14) and a substrate (10) bonded to the body of polycrystalline superhard material along an interface (18). The substrate comprises a substrate body and a first end surface ( )20 forming the interface, the first end surface of the substrate comprising 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 (h) from the cutting face along the peripheral side edge (13) 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. There is also disclosed a method of making such a superhard polycrystalline construction.
