PROBLEM TO BE SOLVED: To provide a pipe cutter which can excellently cut a pipe having a three-layer structure with a soft layer and a hard layer mixed in a state of holding a circular cut surface.SOLUTION: A pipe cutter 10 cuts a pipe having a three-layer structure with a soft layer and a hard layer mixed, and includes: a main body part 20; a roller 26 which is arranged on the main body part 20 and is abutted on an outer peripheral surface of the pipe in cutting the pipe; and a disc-like cutting blade 12 which is abutted on the outer peripheral surface of the pipe to cut the pipe, and includes a support part 12a rotatably supported with respect to the main body part 20, a cutting part 12b extending from the support part 12a with a certain thickness to an outer side, and a blade edge part 12c which forms a blade edge of the cutting blade 12 and has a cross section of an isosceles triangle shape. A thickness of the cutting part 12b is in a range of 1.0-1.2 mm, and a tip end angle of the blade edge part 12c is in a range of 20°-30°.SELECTED DRAWING: Figure 1 |
