Abstract
A method of producing a tool insert is disclosed. A body () of a superabrasive material having major surfaces on each of opposite sides thereof is provided. It is typically an abrasive compact disc such as a PCBN or a PCD disc, for example. An array of spaced cores () filled with hard metal, such as cemented carbide, for example, extends from one major surface to the opposite major surface. The body is severed from one major surface to the opposite major surface along intersecting, transverse lines () around the respective hard metal cores to produce the tool insert. The body may include an interlayer () of hard metal intermediate the opposite major surfaces, preferably the same hard metal as the cores, such that the cores are integrally formed with the interlayer.
