The Turbo Chain Cutter from USB - Sewer Equipment Corporation is made of tempered stainless steel and offers drive and thrust efficiency. Its small, compact design permits the cutter to navigate bends or curves in the pipe. The chain retainer is driven by a high-performance turbine that’s effective in the removal of roots, grease and mineral deposits from 4- to 6-inch sewer lines. The cutter requires low maintenance and no lubrication, and comes standard with ceramic inserts. It can be used with recycled water. Carbide bits can be welded onto the chain. 866/408-2814; www.usbsec.com.
