The RIDGID 238-P (42878) Powered Soil Pipe Cutter is used to cut a variety of cast iron soil pipe, concrete, and clay pipe. It is a compact unit that is ideal for use in close quarters. The 238-P Soil Pipe Cutter is designed to be actuated by a battery powered, corded or pneumatic 1/2" drive impact tool. It can also be used manually with the included 1/2" drive ratchet or a 1 1/8" wrench (sold separately) for up to 4" nominal pipe. The 238-P uses a chain equipped with cutter wheels that is tightened around the pipe until the pipe breaks. The 238-P will cut service weight and no-hub cast iron soil pipe up to 8" nominal diameter. The feedscrew is equipped with a hand knob for fast manual adjustment. A unique hooking mechanism makes connecting the chain easier.
