Abstract:
A coated cutting tool includes a substrate and a coating of one of more layers. The coating includes a layer of α-Al2O3 of a thickness of 1-20 μm deposited by chemical vapour deposition (CVD). The α-Al2O3 layer exhibits an X-ray diffraction pattern and wherein the texture coefficient TC(h k 1) is defined according to the Harris formula, wherein 1
