  • CVD coated cutting tool insert
    Patent number: 7150772
    Abstract: The present invention relates to a coated cemented carbide insert (cutting tool), particularly useful for milling of stainless steels and super alloys but also milling of steels in toughness demanding applications. The cutting tool insert is characterised by a cemented carbide body comprising WC, NbC and TaC, a W-alloyed Co binder phase, and a coating comprising an innermost layer of TiCxNyOz with equiaxed grains, a layer of TiCxNyOz with columnar grains and a layer of ?-Al2O3.
    Type: Grant
    Filed: May 18, 2004
    Date of Patent: December 19, 2006
    Assignee: Seco Tools AB
    Inventors: Andreas Larsson, Anette Sulin, Lena Petersson, Sakari Ruppi
  • Coated cutting tool insert
    Patent number: 6890632
    Abstract: Coated cemented carbide inserts (cutting tool), particularly useful for milling at high cutting speeds in steels and milling in hardened steels are characterised by a WC—Co cemented carbide containing NbC and TaC and a W-alloyed binder phase and a coating including a first, innermost layer of TiCxNyOz with equiaxed grains, a second layer of TiCxNyOz with columnar grains and at least one layer of Al2O3 composed primarily of the ?-phase.
