For the excellent properties, super-hard tool material has received much attention from researchers. The development of super-hard tool material for high-speed cutting could brought high machining quality and surface precision. For an engineer, adopt high performance of tool material, for example wearing resistance, high stability of PCD (polycrystalline diamond) and PCBN (poly cubic boron nitride) can get more information for obtaining higher finished surface quality that cannot acquire just by common cutting process. This paper introduces super-hard cutters materials (PCD and PCBN) development, and discusses several material properties. The features of materials used in different cutting fields are given.
