Abstract
A tool having a base body of carbide, cermet, ceramic, steel or high speed steel and a single-layer or multi-layer wear-protection coating applied thereto in a CVD process, wherein the wear-protection coating has at least one TiAlCNlayer having stoichiometry coefficients 0.70≤x<1.0≤y<0.25 and 0.75≤z<1.15 wherein the TiAlCNlayer is of a thickness of 1 μm to 25 μm and has a crystallographic preferential orientation, which is characterized by a ratio of the intensities of the X-ray diffraction peaks of the crystallographic {111} plane and the {200} plane, wherein I{111}/I{200}>1+h (ln h), wherein h is the thickness of the TiAlCNlayer in micrometer.
