スローアウエイチツプ。[Claims for Utility Model Registration] (1) In a throw-away tip that is polygonal, has a breaker groove along the cutting edge, and has a plurality of protrusions on the bisector of the nose, A first protrusion is provided nearby, a second spherical protrusion is formed at a certain distance from the protrusion or partially overlaps with the protrusion, and a third spherical protrusion is formed that overlaps only near the highest part of the second spherical protrusion. A truncated dome-shaped process is provided,
and the shortest distance between the cutting edge and the point where the first projection and the second spherical projection intersect with the breaker groove is a first distance.
The cutting edge is formed so that the distance l 1 to the second protrusion > the distance l 2 to the second protrusion, and furthermore, the cutting edge has a straight cutting edge near the nose, followed by a straight cutting edge in the center of the cutting edge when viewed from the side. A throw-away tip characterized in that it is combined with a concave cutting edge having an inclined surface that descends in the direction. (2) In the throw-away tip according to claim 1 of the utility model registration, the first and second protrusions are provided at approximately the same height as the cutting edge of the nose portion, and the first protrusion is located at the top of the tip. A throw-away chip characterized by being formed so as to be inclined toward the center of the chip. (3) In the throw-away chip according to claim 1 or 2 of the utility model registration claim, the third
The throw-away tip is characterized in that the protrusion is at the same height as the central boss surface, which is located higher than the height of the cutting edge of the nose part.
