とを特徴とするボールエンドミル。[Claims for Utility Model Registration] The tip of the tool body that rotates around the axis has an arcuate cutting edge whose rotation locus around the axis is approximately spherical, and the tool body is connected to the rear end of the arcuate cutting blade. In a ball end mill equipped with a plurality of throw-away tips having straight blades whose rotation locus around the axis is approximately cylindrical, each of the throw-away tips starts from a position spaced from the axis from the inside. A bottom cutter is formed that extends obliquely toward the tip of the tool body toward the outside, and the arcuate cutting edge is formed from the end position of the bottom cutter, and the end of the bottom cutter is located at the end of the arc of the arcuate cutter. 15° to the axis pointing from the center toward the tip
A ball end mill characterized in that the ball end mill is formed at an angle of 30° or less.
