Claim Text:
1. A coated cutting tool comprising: a substrate; and a coating, the coating including a layer of MTCVD TiCN, and a layer of α-Al where I(hkl)=measured intensity (integrated area) of the (hkl) reflection, I n=number of reflections used in the calculation, and the (hkl) reflections used are (012), (104), (110), (113), (116), (300), (214) and (0 0 12), and wherein TC(0 0 12) is higher than 5, and wherein a full width half maximum (FWHM) of a rocking curve peak of a (0 0 12) plane of the α-Al 2 O 3 using X-ray diffraction as measured on a clearance face of the cutting tool is FWHM lower than 30°, and wherein the TiCN layer exhibits an X-ray diffraction pattern, as measured using CuKα radiation, wherein the relation between the integrated area intensity of a 220 peak and the integrated area intensity of a 311 peak, I 220 /I 311 , is lower than 3.
