Abstract
A coated cutting tool includes a substrate and a coating layer formed onto the surface of the substrate. The coating layer contains an outermost layer. The outermost layer contains NbN. The NbN contains cubic NbN and hexagonal NbN. When a peak intensity at a (200) plane of cubic NbN is made I, a peak intensity at a (101) plane of the hexagonal NbN is made I, and a sum of peak intensities at a (103) plane and a (110) plane of the hexagonal NbN is made Iin X-ray diffraction analysis, a ratio [I/(I+I)] of Ibased on a sum of Iand Iis 0.5 or more and less than 1.0, and a ratio [I/(I+I)] of Ibased on a sum of Iand Iis 0.5 or more and 1.0 or less.
