  • Patent number: 10710168
    Abstract: The hard coating layer of the cutting tool includes a complex nitride or complex carbonitride layer expressed by the composition formula: (Ti1-xAlx)(CyN1-y). xavg and yavg satisfy 0.60?xavg?0.95 and 0?yavg?0.005. xavg is an average content ratio of Al in a total amount of Ti and Al, and yavg is an average content ratio of C in a total amount of C and N. Some crystal grains composing the complex nitride or complex carbonitride layer have a cubic structure. In crystal grains having the cubic structure, the average crystal grain misorientaion is 1 degree or more; or 2 degrees or more, based on analysis of the polished surface perpendicular to a surface of the layer. A peak exists in 1-2 degrees of the average crystal grain misorientation in the frequency distribution of the average crystal grain misorientation and the area ratio.
