ABSTRACT:
A method of producing a tool insert which comprises a central metal portion having edge regions of superabrasive material bonded thereto and presenting cutting edges or points for the tool insert is disclosed. A body (50) having major surfaces on each of opposite sides thereof, each having spaced strips (64) of superabrasive material, typically abrasive compact such as PCBN or PCD, for example, separated by a metal region or regions, such as cemented carbide, is provided. Each superabrasive strip of one major surface is arranged in register with a superabrasive strip of the opposite major surface. Alternatively, each superabrasive strip extends from one major surface to 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 the respective superabrasive strips to produce the tool insert.
