請求項１記載のスローアウエイ転削工具。[Claims for Utility Model Registration] (1) A groove opening at the tip and outer periphery of the tool body is formed on the outer periphery of the tip of the tool body, which is rotated around the axis, and a flat plate-shaped throw is formed in the groove. A chip mounting seat is formed with a restraining surface that abuts against the side surface of the throw-away chip to position the throw-away chip, and the throw-away chip is mounted on the chip mounting seat with one main cutting edge formed on its ridgeline. In the throw-away type milling tool, which is detachably mounted in a state in which the tip protrudes toward the outer circumference of the tool, the restraining surface of the tip mounting seat is connected to the rear end of the first main cutting edge facing toward the proximal end of the tool. is tilted so as to draw an arc locus 0.03 mm to 0.09 mm smaller in radius around the tool axis than the tip of the first main cutting edge facing toward the tool tip side. . (2) The throw-away milling tool according to claim 1, wherein a supporter is removably inserted into the groove of the tool body, and the tip mounting seat is formed at the tip of the supporter.
