Title: COATED CUTTING TOOL
Abstract:
The present invention is a coated cutting tool with a base material and a coating layer provided on the base material. The coating layer has an upper layer and lower layer that are laminated in order from the base material side to the surface of the coating layer and that respectively satisfy conditions such that "at least one {422} plane of the TiCN particles located on the side of the lower layer closest to the surface and at least one {006} plane of the α-Al2O3 particles located on the side of the upper layer closest to the base material and directly above the TiCN particles are roughly parallel, and at least one {111} plane of the TiCN particles and at least one {110} plane of the α-Al2O3 particles are roughly parallel," and "at least one {111} plane of the TiCN particles located on the side of the lower layer closest to the surface and at least one {006} plane of the α-Al2O3 particles located on the side of the upper layer closest to the base material and directly above the TiCN particles are roughly parallel, and at least one {422} plane of the TiCN particles and at least one {110} plane of the α-Al2O3 particles are roughly parallel."
