Abstract
A coated cutting tool has a substrate of cemented carbide, cermet, ceramics, steel or cubic boron nitride and a multi-layered wear resistant coating deposited thereon has a total thickness from 4 to 25 μm. The multi-layered wear resistant coating includes a TiAlCN layer (a) represented by the formula Ti1-xAlxCyNz with 0.2≤x≤0.97, 0≤y≤0.25 and 0.7≤z≤1.15 deposited by CVD, and a κ-AlOlayer (b) of kappa aluminium oxide deposited by CVD immediately on top of the TiAlCN layer (a). The Ti1-AlxCyNz layer (a) has an overall fiber texture with the {111} plane growing parallel to the substrate surface and a {111} pole figure, measured over an angle range of 0°≤α≤80° and the κ-Al2O3 layer (b) has an overall fiber texture with the {002} plane growing parallel to the substrate surface and a {002} pole figure, over an angle range of 0°≤α≤80°.
