Abstract:

Thread restoring tool which is simple, accurate and inexpensive for cleaning and restoring defective internal threads of pipe connecting members. The tool comprises a pair of levers pivotally mounted to a cross link at approximately the midpoint of the levers and thread cutting dies mounted at the outer terminal ends of the levers remote from the hand grip portions of the levers. The hand grips are initially spread apart to position the cutting dies together to permit positioning internally of the female threads of a connecting member. The hand grips are then closed to seat the cutting dies and permit tracking in the threads. Application of hand pressure and rotation of the tool causes a cutting action.
