Abstract: A tool for removing unwanted metal from the inside of a pipe weld joint that is being repaired between two pipe sections. The tool is designed to be passed into the joint region after the defective weld segment has been removed. The tool consists of an elongated shank integral with a circular cutting segment having teeth on the upper surface thereof for removing unwanted metal from the inside of the weld joint. The shank and the circular body section are both thin enough to permit the body section to be passed through the repair opening left behind by the removal of the defective weld section. The shank is adapted to be coupled to a power drive for rotating the cutting segment at a desired speed.
