Abstract
A coated material for a cutting tool can realize long life-time under severe cutting processing conditions such as high-speed processing, high-feed-rate processing, higher hardness of a material to be cut, cutting of a difficult-to-cut material, etc. In a coated material in which a coating is coated on the surface of a substrate, at least one layer of the coating is a hard film having a cubic metallic compound which includes at least one metal element M selected from Al, Si, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W, and at least one element selected from C, N and O. An X-ray intensity distribution of an α axis in a pole figure for a (111) plane of the hard film has a maximum intensity in an α angle range of 75 to 90°, and an X-ray intensity distribution of an α axis in a pole figure for a (220) plane of the hard film has a maximum intensity in an α angle range of 75 to 90°.
