Tool insert

A method of producing a tool insert having superabrasive cutting points or edges is disclosed. A body ( 10 ) of a hard metal having major surfaces ( 12, 14 ) on each of opposite sides thereof, such as a cemented carbide disc, is provided. Each major surface of the body has an array of pockets ( 12 ) filled with a superabrasive material, typically an abrasive compact such as PCBN or PCD, for example. A pocket of one major surface is arranged to be in register with a pocket of the opposite major surface. The body is severed from one major surface to the opposite major surface along at least two sets of planes intersecting at or in respective superabrasive filled pockets to produce the tool insert. The severing of the body is carried out in such a manner as to expose the superabrasive material to form a cutting tip or edge in the tool insert.
