The Rotodrill nozzle from Enz USA has a rotating front jet for improved cutting performance. It can be used to help clear blocked or frozen pipes, and move heavy debris. It has ideal propulsion but can also be used in hydroexcavation by plugging off the thrust jets. It is available in 1/2-, 3/4- and 1-inch systems. 877/369-8721; www.enzusainc.com.
