Abstract
A coated cutting tool includes a substrate and a coating. The coating has an inner layer of 4-14 μm thick TiAlN, an intermediate layer of 0.05-1 μm TiCN and at least one outer layer of 1-9 μm α-AlO. The α-AlOlayer exhibits an X-ray diffraction pattern, as measured using CuKα radiation and theta-2theta scan. A texture coefficient TC(hkl) is defined according to Harris formula, wherein the (hkl) reflections used are (0 2 4), (1 1 6), (3 0 0) and (0 0 12), I(hkl)=measured intensity (peak intensity) of the (hkl) reflection, I0(hkl)=standard intensity according to ICDD's PDF-card No. 00-042-1468, n=number of reflections used in the calculation, and 3<TC(0 0 12)<4.
