    摘要： In a drill, a negative hind is provided on a rake face, and a ridge line at an intersecting position of the negative land and a flank face, a ridge line at an intersecting position of the flank face and a margin, and a ridge line at an intersecting position of the negative land and the margin are convex faces in a longitudinal rectangular cross section. When a curvature radius of the convex face of a first ridge line at the intersecting position of the flank face and the negative land is 1, at curvature radius of the convex face of a second ridge line at the intersecting position of the flank face and the margin is 0.8 to 1.5 times the curvature radius of the first ridge line, and a curvature radius of the convex face of a fourth ridge line at the intersecting position of the negative land and the margin is 1.5 to 3.0 times the curvature radius of the first ridge line.

    摘要： Forming coated cemented carbide inserts, particularly useful in fine turning of super alloys. The inserts are characterized by a composition of a cemented carbide of WC, about 4.0 wt-% Co to about 7.0 wt-% Co, about 0.25 wt-% Cr to 0.50 wt-% Cr, and a coercivity (Hc) of about 28 kA/m to about 38 kA/m. The coating comprises a single (Ti1-xSix)N-layer, where x is between about 0.1 and about 0.25, with a crystal structure of NaCl type and a total thickness between about 0.5 μm and about 2.0 μm with a strong (200)-texture.
