The Flex / Curved heavy duty cutter blades are great for moderate roots, scale and grease. They are supplied three per chuck in a triangular position that allows constant contact with pipe walls as the hydraulic root cutter rotates.
This allows a complete scouring of the pipe wall. The blades are made of high tempered spring steel and heat treated to 50-54 Rockwell at 1 ¼”wide x 1/8” thick. Sizes are provided from 4”-18” in sets of three blades. The hub comes with a grade 5 bolt and nylon nut to secure the hub to the hydraulic root cutter motor shaft .
Made in the USA.
