Abstract
A cutting element (30) includes a substrate (40); and a body of superhard polycrystalline material (34) bonded to the substrate (40) along an interface, the body of superhard polycrystalline material having a peripheral side edge (42). The body of superhard polycrystalline material has a cutting surface (34); a plurality of spaced apart cutting edges (36) extending to the cutting surface (34) through respective chamfer portions (38), the cutting edges being spaced around the peripheral side edge; a plurality of recesses/regions (48) extending from the cutting surface (34) towards the substrate, adjacent cutting edges (36) being spaced apart by a respective one of said recesses/regions (48); and a protrusion or recessed region extending from the cutting surface about a central longitudinal axis of the cutting element. A method of making such a cutting element is also disclosed.
