Claims

[Scope of utility model registration request]

Along the outer periphery of the tip of the tool body in the circumferential direction, the cutting edges located on the outer periphery side are the main cutting edges, and the main cutting edges are arranged on the tip side of the tool body and on this tip side. A throw-away tip with adjacent cutting edges formed thereon and a throw-away tip arranged on the proximal end side of the tool body with the main cutting edge and adjacent cutting edges formed on the proximal end side alternately. In a throw-away milling tool that is detachably attached, the throw-away tip is
The rake face of the main cutting edge formed on at least one pair of opposing sides of the upper surface is such that the maximum thickness between the upper surface and the lower surface forming the seating surface is the cutting edge of the main cutting edge and the cutting edge. Connecting the maximum thickness portions of the pair of main cutting blades located at a location biased towards the tip side of the cutting blade from the center with the rear end, and the shape of the side portions forming on opposing sides. A throw-away milling tool characterized in that it is formed of a convex curved surface that is symmetrical with respect to the imaginary line when viewed from the side in a direction along the imaginary line.
