The uppermost layer of the inner layer in contact with the outer layer is composed of a compound at least containing Ti and at least one of nitrogen and boron. The outer layer is constituted by an alumina layer or an alumina-containing layer. In a region involved in cutting, the outer layer satisfies B/A?0.9 where A ?m is the average thickness at the flank face (3) side and B ?m is the average thickness at the rake face (2) side.

    Abstract: A coated cutting insert according to the present invention includes a substrate, a base layer formed on the substrate, and an indicating layer formed on a part of the base layer. The base layer exhibits a color different from that of the indicating layer. The indicating layer is formed on the base layer, in at least a part of a surface including a cutting-edge portion and a rake face except for a flank face. When a surface relative roughness Ra of a breaker recess portion or a land portion of the rake face is set to A?m and a surface relative roughness Ra of the flank face is set to B?m, relation of B/A?1 is established.
