Abstract: A method of treatment and processing of tools for machining of workpieces by cutting is described, in particular milling tools. These tools are made up of a high-strength steel, carbide or ceramic, and are provided with at least one cutting flank and a flute, which cutting flank is provided with a cutting edge on the cutting side. In a coating installation, the tool is provided with a first coating which is wear-resistant against abrasion. Afterwards a bevel is ground on each of the cutting edges. A second coating, which is resistant to crater wear, is applied to the ground bevel in a coating installation. Tools are thereby obtained that are characterized by high abrasion resistance and high resistance to wear and tear, in particular during machining of difficult materials at high cutting speed.
