Zusammenfassung:PROBLEM TO BE SOLVED: To perform surface coarseness fine cutting at a high speed. SOLUTION: Cut surfaces 1, 2, and 3 having different curvatures of radius are provided at a tip. The curvature of radius R1 of tipmost part, a curvature of radius R2 adjacent to the R1 , and a curvature of radius R3 adjacent to the R2 satisfy a relation of formulas of 11R1
