Lumberjack (LJ050)

The Lumberjack is a high speed (up to 50 000 rpm), low torque multi purpose cutter. The rotation of the Lumberjack is powered by the water pressure supplied by a common sewer cleaning jetter truck.

Although it is designed to cut roots, many of our customers use it for cutting concrete, grease, mineral and chemical deposits, tuberculate and protruding laterals. We know of no other cutter that is as versatile, reliable and user friendly for common, everyday cutting jobs. The Lumberjack series operates in pipe sizes from 3 (75 mm) up to 36 (900 mm).

The bearings are sealed, grease lubricated and water cooled. No lubrication is required after use. It works and works with very little maintenance or care required. The standard and optional cutting accessories are designed to eliminate potential pipe damage. The low torque high-speed feature and benefit prevents getting stuck, spinning off the hose or cutting through the host pipe.
