摘要： The hard coating layer of the cutting tool includes a complex nitide or complex carbonitride layer expressed by the composition formula: (Ti 1-x Al x )(C y N 1-y ). x avg and y avg satisfy 0.60 ≤ x avg ≤ 0.95 and 0 ≤ y avg ≤ 0.005. x avg is an average content ratio of Al in a total amount of Ti and Al, and y avg is an average content ratio of C in a total amount of C and N. Some of crystal grains composing the complex nitrdie or complex carbonitride layer have a cubic structure. In crytal grains having the cubic structure, the average crystal grain misorientaion is 1 degree or more; or 2 degress or more, based on analysis of the polished surface as a surface in the perpendicular direction to a surface of the layer. A peak exists in a range of 1-2 degrees of the average crystal grain misorientation in the frequency distribution of the average crystal grain misorientation and the area ratio.
