    摘要: A surface-coated cutting tool which comprises a substrate, an inner coating layer formed on the substrate with a compound comprising Al, at least one element of Cr and V, and one or more elements selected from nitrogen, carbon and oxygen, and an outermost coating layer formed on the inner layer with a carbonitride of TiSi. The surface-coated cutting tool is suitably used for a drill, an end mill, an edge replacement type of tip for milling and turning, a metal saw, a gear cutting tool, a reamer, a tap, and the like, and exhibits the improved resistance to exfoliation and wear, as compared to a conventional tool.

    摘要: A surface-coated cutting tool includes a coating layer (108) formed on a substrate (104), wherein assuming that the average thickness of the coating layer (108) on a first surface (106) and a second surface (107) of the substrate (104) is A, a difference between the maximum and minimum thicknesses of the coating layer (108) is larger than 0.04 × A. Also, a surface-coated cutting tool includes a coating layer (108) formed on a substrate (104), wherein assuming that the average thickness of the coating layer (108) on a first surface (106) of the substrate (104) is B1, and the average thickness of the coating layer (108) on a second surface (107) of the substrate (104) is B2, a value obtained by dividing an absolute difference value between B1 and B2 by a larger value of B1 and B2 is larger than 0.04.

    摘要: A coated cutting insert (1) according to the present invention includes a base layer formed on a substrate (8) and an indicating layer formed on a part of the base layer. The indicating layer is formed on a flank face (3), on the base layer on the entire surface or a part of a region A2 except for a specific region A1, and on a rake face (2), on the base layer on the entire surface or a part of a region B2 except for a specific region B1. In the region A1 and the region B1, the base layer is exposed at the surface, and has compressive residual stress in one or both of the region A1 and the region B1.
