    • 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°.
    • 用于切削工具的涂层材料可以在严格的切割加工条件下实现长寿命,例如高速加工,高进给速度加工,待切割材料的较高硬度,难切割材料的切割 等等。在其中在基材的表面上涂布涂层的涂覆材料中,至少一层涂层是具有立方金属化合物的硬膜,其包括至少一种选自Al,Si, Ti,Zr,Hf,V,Nb,Ta,Cr,Mo和W以及选自C,N和O的至少一种元素。(111)的极图中α轴的X射线强度分布, 硬膜的平面的α角范围的最大强度为75〜90°,硬膜的(220)面的极图中的α轴的X射线强度分布具有最大强度 α角范围为75〜90°。
