Abstract
In a hard coating layer that contains at least any of a layer of a complex nitride or a complex carbonitride (composition formula: (TiAl)(CN)) of chemically-vapor-deposited Ti and Al, a layer of a complex nitride or a complex carbonitride (composition formula: (TiAlMr)(CNi)) of Ti, Al, and Me, and a layer of a complex nitride or a complex carbonitride (composition formula: (CrAl)(CN) of Cr and Al in a surface-coated cutting tool, some crystal grains that form the layer of a complex nitride or a complex carbonitride have cubic structures, and a predetermined average crystal grain misorientation and inclined angle frequency distribution are present in the crystal grains that have cubic structures.
