Claims

[Scope of utility model registration request]

A plurality of throw-away chips each having a main cutting edge formed on the ridge portion of the upper surface on the outer periphery side of the tool body are arranged on the outer periphery of the tip of the tool body. In a throw-away milling tool that is detachably attached continuously in the axial direction of the tool body in the rotation locus, the throw-away tip has an upper surface that intersects with the main cutting edge and a center point of the upper surface. Draw a concave curve that is symmetrical to the center in a cross-sectional view along one reference line that passes through the center, and draw a concave curve that is symmetrical to the center in a cross-sectional view along another reference line that is orthogonal to the first reference line and passes through the center of the upper surface. A throw-away milling tool characterized by being formed with a curved surface that draws a symmetrical convex curve.
