Claims

[Scope of utility model registration request]

The outer periphery is approximately a plate shape of an equilateral triangle, and each side of the upper surface thereof is formed with a cutting edge that draws a convex arc with a radius larger than the radius of the circumscribed circle of the equilateral triangle, and the cutting edges that are adjacent to each other are A V-shaped notch extending from the upper surface to the lower surface is formed between the tip and the rear end, and a wall surface of each notch from the tip of the cutting blade to the lower surface is connected to the tip of the cutting blade. The rake face is formed to be inclined toward the rear end side of the cutting blade adjacent to the straight line connecting the arc center of the cutting blade, and is along the cutting blade from the tip of the cutting blade to the upper surface. 1. A throw-away chip characterized in that it is formed by a plurality of continuous sloped surfaces that are each sloped at different angles with respect to the top surface.
