Abstract

A method of making a superhard construction includes providing a polycrystalline superhard (PCS) structure comprising bonded grains of a superhard material, providing an aggregated mass comprising grains of the superhard material, and providing a substrate having a recess configured for accommodating the PCS structure. The PCS structure is placed into the recess with the aggregated mass of superhard grains positioned adjacent the PCS structure to form an unjoined assembly. Pressure and heat are then applied to the unjoined assembly to join the aggregated mass to the PCS structure and form the superhard construction.
