ABSTRACT:
A U-shaped body member has key slots adjacent opposite ends thereof arranged to have removable connection at spaced points in a chain of a chain pipe wrench. A cutter bit projects adjustably beyond the bottom portion of the body member for cutting a pipe peripherally by multiple turns of the wrench around the pipe in a reverse direction from that at which the lever handle has gripping connection on a pipe. Guide and gauge wheels are provided on opposite sides of the cutter bit for guiding it in a cut and for maintaining the depth of the cut as determined by adjustment of the cutter bit.
