The Lumberjack cutting nozzle from NozzTeq is a low-torque, high-speed cutter for use with high water pressures. It is ideal for cutting roots, but it’s also commonly used to cut grease, tuberculation, protruding laterals and other buildups. Because it’s low torque, it’s unlikely to cut through host pipes. The bearings are sealed, grease lubricated, water cooled and largely maintenance-free, as water-cooled bearings don’t need additional lubrication and are long lasting. The cutters rotate at a minimum speed of 10,000 rpm with flow rates from 10 to 250 gpm at varying pressures. They operate in pipes from 3 to 48 inches. All models clean with chain links, with optional cutting blades for severe blockages. All models come with a propelling jet housing, with tow rings available. 866/620-5915; www.nozzteq.com.
