Cold cut large diameter steel, most stainless steel, ductile and cast iron pipe in close quarters. Modest clearance needed for all models (see chart at right). Each cutter is supplied with a slip-on handle that is used to turn the cutter around the pipe in one direction. The handle is also used to tighten the cutter every half revolution. Best manual cutters for ductile iron. With good leverage from long handle, pipe snaps off squarely before wheel penetrates halfway through pipe. Cutters have heavy-duty frames. All sizes use the same cutter wheels: either RCS8-36 for steel/stainless steel and RCI8-30 for ductile and cast iron. RCX wheels cut up to 25/32” wall thickness for steel pipe.
