ABSTRACT:
A pipe wrenching tool adapted to be powered by a hand held power drive mechanism is formed with a support for a drive wheel and an idler wheel with the idler wheel being movable with respect to the drive wheel to adjust the tool for differing sizes of pipe. The tool is adapted to interface transversely to the axis of the pipe to be wrenched with the drive wheel engaging the pipe without requiring a part of the tool to circumscribe the pipe. The rotational axis of the idler wheel and rotational axis of the drive wheel are off-set with respect to each other to cause the pipe being wrenched to be forced into the tool. The tool is adapted at both sides to have the drive source attached at the side of the tool away from the pipe so that the tool may be used to engage and wrench pipe in confined spaces. Only the wheels of the tool are rotated; the tool need not rotate with respect to the pipe.
