Abstract: The present invention discloses a coated cutting tool insert particularly useful for dry and wet machining, preferably milling, in low and medium alloyed steels, stainless steels, with or without raw surface zones under severe conditions such as vibrations, long overhang and recutting of chips. The insert is characterized by WC—Co cemented carbide with a W and Cr alloyed Co-binder phase and a coating including at least three TiCxNyOz layers and a top layer at least on the rake face of a smooth ?-Al2O3.

Abstract: The present invention discloses a coated cutting tool insert particularly useful for dry and wet machining, preferably milling, in low and medium alloyed steels, stainless steels, with or without raw surface zones. The insert is characterized by a WC-TaC-NbC-Co cemented carbide with a W alloyed Co-binder phase and a coating including an innermost layer of TiCxNyOz with columnar grains and a top layer at least on the rake face of a smooth ?-Al2O3.

Abstract: The present invention relates to PVD coated cemented carbide cutting tool inserts roughing to finishing milling operations. The cemented carbide cutting tool insert comprises a substrate and a wear resistant coating. The substrate comprises in addition to WC, from about 5.5 to about 8.5 wt-% Co and Cr such that the Cr/Co weight ratio is from about 0.08 to about 0.12 and also small amounts of Ti and Ta. The wear resistant coating is a homogeneous AlxTi1-xN-layer with x equals from about 0.6 to about 0.67. The thickness of this layer is from about 1.2 to about 3.6 ?m.

Abstract: A coated cutting tool insert is disclosed particularly useful for dry and wet machining, preferably milling, in un-, low- and high alloyed steels and cast iron, with or without raw surface zones. The insert is characterized by a WC—TaC—NbC—Co cemented carbide with a W alloyed Co-binder phase and a coating including an innermost layer of TiCxNyOz with columnar grains and a top layer, at least on the rake face, of a smooth ?-Al2O3.
