PROBLEM TO BE SOLVED: To provide an end surface working device certainly removing burrs growing on a ruptured surface of a torque shear type high tension bolt and to scatter no metal pieces in the circumference. SOLUTION: This end surface working device has: a tool 10 for deburring; a rotating mechanism R to rotate the tool for deburring; and a metal powder collecting mechanism to catch metal powder. The tool 10 for deburring is constituted free to move in the central axial direction (arrow Y in the drawing 1) of the torque shear type high tension bolt 1. COPYRIGHT: (C)2009,JPO&INPIT
