摘要：
The invention relates to a cutting tool having a base body and a multilayer coating which is applied thereto and comprises, optionally in addition to further layers, a plurality of main layers A and intermediate layers B applied alternately directly on top of one another, wherein the main layers A and the intermediate layers B are in each case metal oxide layers produced by the PVD process, the thickness of the main layers A is in the range from 4 nm to 1 µm and the thickness of the intermediate layers B is in the range from 2 nm to 50 nm and the ratio of the thicknesses of the intermediate layers B to the thicknesses of the main layers A is in the range from 1:2 to 1:100.
