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.
