    Abstract: A coated turning insert particularly useful for turning in stainless steel is disclosed. The insert is characterized by a WC—Co-based cemented carbide substrate having a highly W-alloyed Co-binder phase and a coating including an inner layer of TiCxNyOz with columnar grains followed by a layer of fine-grained &kgr;-Al2O3 and a top layer of TiN. The layers are deposited by using CVD-methods.

    Abstract: The present invention relates to method of making a cemented carbide insert, comprising a cemented carbide substrate and a coating. The substrate contains WC and cubic carbonitride phase in a binder phase based of Co and/or Ni and has a binder phase enriched surface zone essentially free of cubic phase. The binder phase enriched surface zone prevails over the edge. By sintering in an atmosphere essentially consisting of nitrogen the thickness of the binder phase enriched zone can be controlled.

    Abstract: A method of making a cutting insert using powder metallurgical methods including using a press with a main pressing direction and a press tool setup with a die, a male core rod, a female core rod, a bottom punch, a top punch and a feed shoe. The insert has a noncylindrical hole perpendicular to the main pressing direction, herein referred to as a cross-hole. A cross-hole with increased dimensional accuracy is obtained if the powder also is compacted by the two core rods.

    Abstract: The present invention relates to a coated cemented carbide cutting tool particularly for turning applications with high toughness demands, of stainless steels of different compositions and microstructures, and of low and medium alloyed non-stainless steels. The cemented carbide is WC-Co based with a composition of 9-12 wt % Co, 0.2-2.0 wt % cubic carbides from elements from group IVa, Va or VIa of the periodic table and balance WC with a grain size of 1.5-2 μm. The binder phase is W-alloyed with a CW-ratio in the range of 0.77-0.95. The coating includes a multilayered structure of the composition (TixAl1−x,)N in which x varies repeatedly between the two ranges 0.45
