Abstract

A coating, particularly for cutting tools, is presented which may be manufactured in a single PVD coating process allowing the making of two-color cutting tools in a simple manner. Between two metallic hard material layers of unlike color a separating layer 11 is provided which, like the other layers, is produced in the same PVD coating process. The separating layer (11) permits the abrasion of the top layer by sandblasting, brushing or the like in very short abrading periods.
