ABSTRACT:
A preform element includes a facing table of superhard material, such as polycrystalline diamond, having a front face, a peripheral surface, and a rear surface bonded to the front surface of a substrate which is less hard than the superhard material. The front surface of the substrate is formed around its periphery with an annular rebate having an inner edge, a number of spaced recesses adjacent the inner edge of the rebate, and projections of superhard material integrally formed on the rear surface of the facing table extend into the rebate and recesses.
