发明名称 Throw-away tip
摘要 <p>A throw-away tip comprises a tip body (11) with a rake face (12) and a flank face (13); a generally plane chamfered surface formed at and along a cutting-edge-forming ridge (14) where the rake face (12) and the flank face (13) cross each other; and a phantom radius surface (18) formed at a crossing ridge between the chamfered surface (17) and the flank face (13), the phantom radius surface (18) being constituted, as in section perpendicular to the cutting-edge-forming ridge (14), by a plurality of lines connected to one another to provide a generally convex shape. A throw-away tip is provided which has an improved wear resistance and a tough cutting edge, prevents occurrence of fins, and enables suppression of chipping and breaking. <IMAGE></p>
