PURPOSE:To realize efficient cutting of pipe in longitudinal and circumferential directions through a single jig by opening the pipe in the intermediate part and to perform cutting without causing damage on a wire body contained therein. CONSTITUTION:Cross pipe through-grooves 18, 18' comprising longitudinal grooves 20, 20', respectively passing upper and lower halves of a pipe 2, and rotary cutting grooves 22, 22' crossing therewith are made in the opposing surfaces of freely openable/closable upper and lower jig bodies 12, 12' holding the pipe 2 to be cut between them. Cutters 26, 26' are disposed, while directing in parallel with the longitudinal grooves 20, 20', at the crossing parts 24, 24' of the cross pipe through-grooves 18, l8'. The pipe 2 is fit in the longitudinal grooves 20, 20' and cut longitudinally while being pulled and then the pipe 2 is fit in the rotary cutting grooves 22, 22' and cut circumferentially through rotation of the jig. |
