ボールエンドミル用スローアウエイチツプ。 A plurality of vertical planes with a predetermined relief angle are formed at equal intervals on the outer peripheral surface that intersects at the ridge line with the rake face facing the direction of rotation when attached to the cutter body that rotates around the axis. In addition, the area between these vertical planes on the outer circumferential surface is a convex arc-shaped flank, and the ridge between the rake face and the flank is a cutting edge, and the cutting edge is used as a rake. At least the vicinity of the intersection with the vertical plane of the rake face is a convex curved surface so as to form a convex curve upwardly, and the ridgeline between the vertical plane and the rake face is a non-cutting edge portion. A throw-away tip for a ball end mill that is characterized by:
