PURPOSE: A tension bite is provided to easily cut a side flange unit of a crank shaft and to prevent cutting edge abrasions. CONSTITUTION: A tension bite comprises a main body unit(10), an elastic unit(20), a through hole(30), and a cutting edge(40). The main body unit is composed of a square metal rod having left and right joining holes(10a,10b). One side of the elastic unit is integrally coupled to the top of the main body unit and is bent in a hook-shape. The through hole is formed at the bottom of a gap between the main body unit and the elastic unit. The cutting edge is welded into a cut unit with ultrasonic waves. The cut unit is cut into an L-shape.
