Abstract: A tool for turning an elongate pipe is disclosed. The tool comprises a base and a drive wheel mounted for rotation on the base. The drive wheel has a cylindrical outer surface may include a plurality of projections extending radially outward from the outer surface of the first drive wheel. The projections extend past the edge of the base. In use, the projections contact a portion of the outer surface of an elongate pipe and turn the pipe with the rotation of the drive wheel. A guide is also mounted for movement on the base. The guide may be a pair of guide arms pivotally mounted on the base. Each guide arm has a free end and a guide roller is mounted for free rotation at each free end of each guide arm. Each guide arm is pivotable to a position wherein the guide rollers hold the elongate pipe against the projections on the outer surface of the first drive wheel.
