I-T-H PIPE CUTTING TOOL ABSTRACT OF THE DISCLOSURE A pipe cutting tool especially adapted to cut the interior of in-the-hole (I-T-H) drill pipe to allow subsequent removal of the pipe above the cut. Due to blasting damage, long sections of I-T-H pipe, otherwise in good condition, cannot be removed because the damaged section prevents the removal of the entire drill string. The tool is adapted to receive power from an external source and includes a frame, a pivoted motor and cutter, and an actuator for pivoting the motor.
