ABSTRACT:
A tubing cutter uses a plier type action for providing cutting force on the tube, and has four cutters that are distributed around the tubing so a small arc of oscillation can be used to cut a tubing. A pair of cutters is mounted on each jaw of the plier-type tool. When the jaws are closed, the axles of the cutters are at the corners of a square in order to provide the optimum geometrical pattern for the cutters. The distance from the center of the cutters to the pivot for the pliers should be about twice the distance between the adjacent cutters. The tool uses only cutters, and no guides, so the tool can be held in position and moved through a small arc; then, the score line will facilitate continued motion on the same line.
