Abstract: A planetary ratchet wrench with an optional add-on pipe cutting tool. The basic tool includes first and second intermeshing gear members, where one of the gear members includes a pair of arcuate shaped segments, pivotally engaged, that open to receive a pipe connection and close to form a continuous circular gear member. To the second of the gear members, a ratchet arm, removably secured to the second gear member, is provided to effect rotation of the respective gear members. Stabilizing arm is provided to allow the rotation of the gear members from a position remote from the meshing gear members. Further, a pipe cutting tool may be an add-on to the tool for rotation with the first of the gear members.
