    摘要: A TiCN-based cermet comprises 5-25 weight % of a binder phase mainly composed of Co and/or Ni, the balance being substantially a hard phase and inevitable impurities, the hard phase being mainly composed of carbide, nitride and/or carbonitride and containing at least Ti and W, the cermet having a cross-section microstructure in which the number of Ti-rich particles having an area of 0.02 &mgr;m2 or more is 1000 or less per a unit area of 1000 &mgr;m2.

    摘要: A cutting insert for a during includes a broken main cutting edge, the ends of which join respective additional edges of the insert by curved nose portions. Each curved nose portion forms a curved cutting edge defined by at least three sequentially arranged curved cutting edge segments defined by respective radii of different sizes. A first of the segments joins one end of the main cutting edge and has a first radius. The next segment has a radius of different length than the first radius and projects farther laterally than the first segment to perform a wiping function.
