Abstract

PURPOSE:To form a pin journal part in the same diameter over the total length or in a diameter gradually increased in accordance with the pin journal part in its position from the end part toward the central part by providing a finishing throw away tip, having a cutting edge, in the root end part of a long-sized broach main unit while forming the cutting edge in a V-shape and tilting a flank of the cutting edge. CONSTITUTION:A finishing tip 2 is formed so as to provide a V-shape in which cutting edges 12, 12 of the tip 2 tilt gradually toward the bottom surface side of a broach main unit 1 in accordance with the broach main unit 1 from its side surface to central part. Simultaneously placing flanks 10b, 10b so as to tilt gradually toward the bottom surface side of the broach main unit 1 in accordance with the broach main unit 1 in its position toward the root end side, the tip 2 is mounted to a mounting seat 8. By the tip thus obtained, a pin journal part can be finished in the same diameter over the total length or in a diameter gradually increased in accordance with the pin journal part in its position from the end part toward the central part.
