Abstract

Chip breaker design (1) made from cubic boron nitride to improve the operating life and the wear resistance of machine material tools. This invention incorporates new and useful complex shapes (4-39). In some preferred embodiments of this invention (1d) the cubic boron nitride layer (101) is bonded to a tungsten carbide substrate (105) for improved cost performance and mounting capabilities.
