摘要
A vertical outer circumferential cutter tip, which has an approximate hourglass shape that is narrower at its middle than at its ends, and all of its eight corners are acute angles. Both sides of the vertical outer circumferential cutter tip are relieved at an angle α. When performing cutting processing upon the side surface of a counter weight with the vertical outer circumferential cutter tip, excessive friction is prevented. The shapes of the upper end portion and the lower end portion of the vertical outer circumferential cutter tip are formed so as to be very gently convexed, and with a relief of an angle β. Abrasion of the upper end portion and the lower end portion of the vertical outer circumferential cutter tip is prevented before the acute angled corner used for cutting is damaged.
