However, there are thousands of signs of cutting tool materials.
Further more, with the development of science and technology, requirements for engineering materials is getting higher and higher, and the materials are widely used in aeronautics and aviation, nuclear energy, composite, biology, function, nano-material, thulium, metal or nonmetal and so on,.
Different tool materials for the same work or identical tool for machining different work materials have diverse tool life, that is, there is no a versatile tool material for various work.
Various tool materials to works can be determined according to Table 9.
