ことを特徴とするスローアウエイチツプ。 It has a polygonal plate-like appearance, and at least one of the upper and lower surfaces is a rake face, and a cutting edge is formed on the ridgeline of the rake face, and extends from the corner of the rake face to the adjacent corner. In a throwaway chip in which a chip breaker groove is formed in a wall portion of a predetermined range, the width of which gradually narrows from the corner toward the adjacent corner, the chip breaker groove is formed in the wall from the corner to the adjacent corner. The distance between the upper and lower surfaces gradually decreases as you move toward the corner of the cutting edge, and the distance between the upper and lower surfaces gradually decreases toward the direction in which the chip breaker groove extends, and the distance between the upper and lower surfaces gradually decreases as you move toward the center from the cutting edge. A throw-away chip characterized by comprising a gradually decreasing slope and a side surface rising from the center edge of the slope in a direction substantially perpendicular to the upper and lower surfaces.
