Rotary sewer cutter CB90

Rotary sewer cutter CB90 for removing limescale and roots from PVC, steel and concrete pipes. The Freeskogel CB90 spray nozzle (also known as a cutting ball) is a round nozzle with a hard metal front that rotates and vibrates. Ideal for unblocking pipes that are clogged more than 50%.

The blades on the side are self-sharpening and therefore do not need to be sharpened. The spherical shape makes the rotary spray nozzle easy to bend and reduces the risk of damage to the pipe. In addition, the CB90 is leak-proof and can be used with recycled water.
