At least one coating layer has the composition Ti—Al—Ta—N and at least one further coating layer has the composition Ti—Al—Ta-Me-N. The component Me is one more elements selected from the group consisting of Si, V, B. The tool, which is preferably a wearing part, is distinguished by a high wear resistance that improves the service life, in particular where high demands are imposed on the tool.
