Abstract

PURPOSE: To extremely shorten a cutting edge for easy machining of a convex surface by leaving a flat surface in the middle of at least one side of the front surface, and by forming a convex face curving in the shorter edge direction of the front surface.
CONSTITUTION: A tip 20 is a square pillar with a basic cross section of rectangle, the width B of whose front surface 21 is made smaller than the width H of the side clearance 22. The front surface 21 is formed to be a convex surface inclining downward from the short side edge 23 of the front surface 21 toward the center, leaving in the center the flat surface part 24 with the same height as that of the short side edge 23 of the front surface 21. the short side curved edge thus formed is made a cutting edge. At the same time, the corner part of the front surface 21 is wholly chamfered. The front surface 21 thus formed, the cutting edge is made extrmely short and the convex surface is machined to curve in the direction of the short side edge so that machining is easily undertaken with no obstructions in front nor in rear.
