るボールエンドミル用スローアウエイチツプ。 It is a plate-shaped plate that is removably fixed to the tip seat provided at the shank end of a throw-away ball end mill.One side is the rake surface and the other side is the seat surface.The center of rotation is attached to one or both sides of the tip. The cutting edge that performs the cutting is made convex, and is continuous with the circular arc-shaped cutting blade on the outer circumferential side so that its rotational projection forms an arc shape when the tool rotates, and the mounting surface corresponds to the contact surface of the shank. A throw-away tip for a ball end mill, characterized in that a groove for discharging chips is formed on the rake face side of the tip.
