Raptor chain cutters from Sewer Pro Shop are made of high-grade stainless steel and are furnished with ceramic nozzle inserts. They require no maintenance and have been designed to be operator-friendly for the municipal and industrial markets. The powerful hydrodynamic tool can be used to remove heavy obstructions caused by roots, grease, mineral deposits or other solid organic material quickly. It is driven by a high-performance turbine that doesn’t require any lubrication. It comes with a guide skid that is continuously adjustable from 6 to 12 inches and can easily convert from a root cutter to a total blockage remover by replacing the chain cutter with a drill head. It can also be used with recycled water. 470-592-1717; www.sewerproshop.com.
