[Claims for Utility Model Registration] A tip pocket is formed along the axial direction on the outer periphery of the tip of the tool body, and a plurality of polygonal plate-shaped throw-away tips are arranged along the tip pocket, and the top surface of the tip pocket is attached to the tip of the tool body. The main cutting edges are located on the outer circumferential surface side and are attached so that the main cutting edges formed on the ridgeline portions of the upper surfaces thereof are continuous in the axial direction of the tool body in their rotation locus,
And the throw-away tip has a side surface from the main cutting edge to the lower surface serving as the seating surface, and a width dimension between these side surfaces at the center of the main cutting edge is larger than each width dimension at both ends of the cutting edge of the main cutting edge. In an indexable milling tool having a convex curved rake face, in the same chip pocket, a throwaway tip with a positive axial rake angle has the same absolute value as the positive axial rake angle. A throw-away milling tool characterized in that a throw-away tip with a negative axial rake angle is mounted so that the difference in number between the chips is 1 or less.
