Abstract
This surface-coated cutting tool is a surface-coated cutting tool having a hard coating layer formed on a surface of a tool body in which the hard coating layer includes at least one orientational Ti compound layer made of a rock salt-type cubic crystal structure containing 35 at % or more of Ti and 30 at % or more of N, a maximum TC value (TC max) is 2.5 or more, and, in the case of measuring crystal orientations, in a plane parallel to the surface of the tool body, of crystal grains for which a plane having the maximum TC value is perpendicular to the surface of the tool body, a full width at half maximum of ϕ scan is 30° or less.
