<p>A coated cutting tool member exhibiting not only a superior wear resistance during a high speed cutting operation in which a significant amount of heat is generated, but also exhibit a superior shipping resistance even when such a cutting operation is performed under severe conditions, such as with a large depth of cut or a large feed. In the coated cutting tool member, a hard coating layer of one of nitride compound and carbonitride compound containing Ti and Al is formed using a physical vapor deposition method at an average thickness of 1 to 10 mu m, and the hard coating layer includes Zr at an atomic ratio of 0.002 to 0.1, and at least one ofY and Ce at an atomic ratio of 0.0005 to 0.05 in a coexistence state. <IMAGE></p> |
