The wear protection coating has a first coat deposited on the base body having a composition of TiaAl(1-a)N, wherein 0.4≤a≤0.6, and a coating thickness of 0.5 μm to 4 μm, and a second coat deposited on the first coat. The second coat includes a sequence of 10 to 80 first and second layers alternatingly arranged one on top of each other. Each of the first and second layers has a thickness of 5 to 100 nm. Each first layer includes nitrides of the elements Ti, Al, Cr and Si, and each second layer has a composition of TixAl(1-x)N, wherein 0.4≤x≤0.6. The first and second coats have up to 10 at-% of further metals, B, C and/or O as impurities in each layer.
