The pipe cutter disclosed herein is made up of a frame having a slide. The frame has a cutting wheel rotatably supported on it and two spaced noncutting wheels supported on the slide. Instead of the two noncutting wheels and one cutting wheel, three cutting wheels may be used or two noncutting wheels and a cutting means of some other form, or any combination of cutting or noncutting wheels. Also, some known cutting means could be used in combination with the noncutting wheels within the scope of the invention. A threaded means is provided to move the slide toward the cutting wheels. The cutting wheels are supported on pins and the pins each have a peripheral groove which receives an O-ring or a C-washer. The O-ring or C-washer is received in a space on the inner face of the guide blocks which receive the pin. The pin is thus held in position in the support by the O-ring or C-washer.
