First introduced by Reed, the captured screw makes the SC49 close-quarter soil pipe cutters both easy to use and less costly. The screw does not have to be manipulated into place which reduces screw and cutter breakage. The fastest way to cut cast iron soil pipe, clay pipe and small diameter concrete pipe is with a chain soil pipe cutter. Great for gray water applications! Reed has improved the original design by providing stronger jaws and more durable adjusting screws which are interchangeable with the original tools. Reed soil pipe cutters are available in a single stroke SC59 model and a ratcheting SC49 model for close quarter work. Multiple use 1/2" ratchet wrench ships with SC49 models. No-Hub Roller Kit is standard on all models. For cutting ductile iron pipe, Reed recommends Hinged Cutters or Low Clearance Rotary cutters. To cut cement lined ductile or ceramic lined ductile, use Reed's Universal Pipe Cutter (UPC) with the blade for cast iron and ductile iron pipe. NOTE: Jaw sets and cutter chains are interchangeable with Wheeler-Rex models. Pressure Screw Assembly available offering heavy duty parts for current and prior Reed models, along with Wheeler-Rex 490. Order #98046 for Reed SC49 models and Wheeler-Rex 490 series; use #98047 for Reed SC59 models.
