摘要 |
The present invention relates to a coated cemented carbide insert (cutting tool), particularly useful for milling at high cutting speeds in alloyed steels, tool steels and milling in hardened steels. The inserts are characterised by a WC-Co cemented carbide containing NbC and TaC and a W-alloyed binder phase and a coating including an inner layer of TixAlyN, 0.8≤x+y≤1.2, with 0.25≤x/y≤1.45, with columnar grains. <IMAGE> |
