(57) [Abstract] [Object] It is an object of the present invention to provide a coated tool having excellent adhesion and wear resistance of a film and having a long tool life. The main components are one or more hard phases of carbides, nitrides and carbonitrides of groups 4a, 5a and 6a of the periodic table and one or two of Fe, Ni, Co, Mo and Cr. The surface of a hard substrate composed of at least one kind of binder phase a selected from the group consisting of carbides, nitrides, oxides, borides, oxycarbides, oxynitrides, oxycarbonitrides, boroborides, boronitrides, and borocarbonides of metals belonging to the group a, 5a, 6a and Al The coating is characterized by being coated with a layer coating or two or more types of multilayer coatings, and formed with projections protruding from the substrate surface into the coating portion. |
