Abstract

The present invention provides a thin film coated on a cutting tool surface made of cemented carbides, cermets or ceramics. According to the present invention, an α-AlOthin film is deposited on a TiAlvBwCxNyOz (v+w+x+y+z=1, v, w, x, y, z≧0) thin film in a thickness of 2-15 μm, so that the ratio of TC (104) (denoting the texture coefficient of the (104) crystal plane of the polycrystalline α-AlOthin film) to TC (012) (denoting the texture coefficient of the (012) crystal) is more than 1.3. Cutting tools coated with such a thin film have improved wear resistance and adhesion.
