Abstract
A coated tool includes a base and a coating layer on the base. The coating layer includes a cubic crystal that includes one or more kinds of elements selected from Groups 4, 5 and 6 in the periodic table, Al, Si, B, Y and Mn, and one or more kinds of elements selected from C, N and O. A maximum peak is in a range of 50° or more in a distribution of X-ray intensity (111) at α axis of a pole figure, the X-ray intensity regarding a (111) plane of the cubic crystal. The intensity at the maximum peak is Imax, a peak width at 0.8 Imax of the maximum peak is 20° or more, and the intensity at 90° is 0.78 Imax or more. A cutting tool includes a holder which includes a pocket at an end, and the coated tool in the pocket.
