Abstract
The paper describes the origins of cemented carbide as a cutting-tool material, the growth of new technology, the ‘indexable insert’ revolution and the mechanical developments that arose from it, and the widening range of applications that resulted along with improvement in the properties of the materials used. The author illustrates how cemented carbide cutting tools are a classic example of the development of a new material being curtailed over a prolonged period by the use of inappropriate design and application procedures which had been established for an earlier material. He shows how the technical needs demanded major R&D investment, which in turn has reshaped the PM industry. PM/0250
