Abstract
A tool for making up and breaking out a drill string at an exit side of a bore. The tool includes a fixed vise and a moveable vise for torqueing a pipe joint, a roller assembly for threading and unthreading adjacent sections of pipe, and a retainer assembly to retain a detached pipe section. The components of the tool are mounted on a frame, which is pivotally connected to a hydraulic machine such as an excavator. Thus, the tool may be manipulated to remove and add sections of pipe to a drill string remote from the primary horizontal directional drill.
