ABSTRACT:
Pipe sections of a drill string are unscrewed by holding one pipe section stationary in a clamping arm, and rotating another pipe section by a turning wrench. The clamping arm includes an adapter that can be replaced by similar adapters sized for different pipe diameter. The turning wrench includes a lug arranged to be contacted by a piston rod and rotated thereby for breaking the bond between the pipe sections.
