Claims

[Scope of utility model registration request]

A plurality of indexable tips, each having a cutting edge on the outer periphery side as a main cutting edge, are disposed on the outer periphery of the tip of the tool body, and the main cutting edges are connected to each other in the axial direction of the tool body in their rotation loci. In the indexable milling tool which is removably attached, the throw-away tip has the rake face of the main cutting edge formed on at least one pair of opposing sides of the upper surface, and the upper surface and the seating surface. The maximum thickness part between the formed lower surface is located at a location that is biased toward the cutting edge tip side from the center between the cutting edge tip and the cutting edge rear end of the main cutting edge, and the shape of the side portion is It is formed by 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 connecting the maximum thickness parts of the pair of main cutting edges formed on opposing sides. A throw-away milling tool that is characterized by:
