The Croco Cleaning Chain (with drill head), is an adjustable grinding chain with a 25mm diameter drill head. It was made for blockage removal and descaling of cast iron and vitrified clay pipes with a diameter from Ø75mm (3″) to Ø250mm (10″)
The drill head makes it suitable for removing failed liner, and reinstatement of junctions, and is perfect for preparation of pipe work for the lining process.
Since it is adjustable, it has the capacity to clean a size down, by simply spreading the connection hubs slightly further apart.
This chain has hard metal teeth fused to the cutting edge which are crossed in opposing directions. This makes it less aggressive than the X-tip.
The drill head provides extra teeth facing the direction in which the shaft is moving. This makes the chain best suited for root removal and grinding up solid blockages. The chain can also be used to remove scale and tuberculation, but not as fast as a circular chain which has more teeth on the surface at any given time.
The tool uses centrifugal force to center itself within the pipe so you can be assured that the entire inner surface of the pipe wall is clean.
It is manufactured from stainless steel links to prevent oxidation, and each chain consists of 3 individual chains. It mounts to the shaft with set screws.
The chain mounts to an 8mm (5/16″),10mm (3/8″) and 12mm (1/2″) flexible shaft.
Sizes range from Ø75mm (3″) to Ø250mm (10″)
