The cutter utilizes a ratched action to provide mechanical advantage for the cut and can be operated in a trench just wide enough to slip the chain around the pipe. The ratchet action is parallel to the pipe allowing work to be done on the ground, in a ditch, enclose quarters or overhead. Features: No vise required- Cutter does not rotate around pipe. Ratchet action cleanly cuts pipe in tight quarters. Hardened deep penetrating cutter wheels make fast clean cuts. No adjustment between cuts. Does not depend on pipe for leverage. Works on irregular shapes.
