The WaMax 100 Milling Nozzle System is milling style nozzle utilized for major blockages involving concrete, asphalt, and significant mineral deposits in lines between 4" to 8" in diameter. The milling system utilizes a turbine style drive with an internal gear reduction system to generate torque to the milling head. The internal gearing also allows the system to be used with much lower GPM jetting machines when compared to other milling systems. The WaMax possesses the capability of a hammer drill that aids in pulverizing material at the blockage. This, in turn aids in the removal of materials down the sewer line. Can also be used for pipe preparation prior to pipe lining. The kit comes complete with the turbine drive motor, skids, extensions, 4" milling head, cutting teeth and one set of attachable saw blades, plus a rigid carrying case. Be sure to select your hose length at the time of order placement to insure maximum performance from the nozzle.
