Abstract
[PROBLEMS] To provide a cutting tool consisting of a hard material improved in the adherence between a substratum of cemented carbide having hard phases bound by a binder metal and a TiN layer superimposed on a surface of the substratum, and provide a process for producing the same. [MEANS FOR SOLVING PROBLEMS] There is provided a cutting tool consisting of a hard material, characterized in that the hard material has a substratum containing hard phases and a binder metal and a TiN layer superimposed on a surface of the substratum, and that the substratum has β-phases consisting of at least one solid solution of carbide, nitride or carbonitride containing W and at least one member selected from among Ti, Ta, Nb and Zr, and that at least some of the β-phases lie at a surface of the substratum, and that the TiN layer has crystals with the same orientation relationship as that of β-phase crystals just above the β-phases of the substratum surface.
