Abstract
Abstract Coating-film furnished coated tools that are lubricative while maintaining resistance to wear are realized by coated tools in which a plurality of coating films is furnished on a base part. Furnished as the coating are one or more layers of, respectively: a first film composed of one compound selected from nitrides, carbides, carbonitrides, oxynitrides and carboxynitrides of TiSi; and a second film composed of one compound selected from nitrides, carbides, carbonitrides, oxynitrides and carboxynitrides of one metal M selected from Ti, Cr, and TiCr. The first film and the second film are laminated in alternation.
