ウエイチツプ。 The main cutting edge is formed on the opposing ridges of the upper surface, and the rake surface is formed on the side surface from the main cutting edge to the lower surface, which is the seating surface.It has a rectangular plate shape and rotates around the axis. In a positive throw-away chip that is mounted on the outer periphery of the tool body with the rake face having a positive axial rake angle, the rake face along the main cutting edge is set between the rake faces at the center of the main cutting edge. A positive throw-away tip, characterized in that it is formed with a convex curved surface whose width dimension is larger than the width dimension between the respective rake faces at the cutting edge tip and the cutting edge rear end of the main cutting edge.
