Heavy-duty chain knocker for PVC pipe, optional drill head, for 10mm & 12mm shaft

This heavy-duty plain chain knocker is designed for cleaning PVC pipe systems where protecting the pipe wall comes first. It removes blockages and roots, grinds away failed liners and descales without damaging the pipe wall.

Suitable for PVC

Unlike the chains for metal and ceramic pipes, this chain has no carbide bits on the cutting edge. That is what makes it suitable for PVC pipes.

For metal and ceramic pipes we offer the heavy-duty versions as a Croco chain and as an X-Tip chain.

Optional drill head

The chain is available with a Croco drill head fitted at the front. It lets you cut roots and grind away failed liners in a controlled way without putting the pipe wall at risk. The drill head opening is 21mm.

Construction

Each set consists of three individual chains with 4mm stainless steel links. That gives the chain both strength and flexibility and prevents oxidation. Adjusting the hub spacing adapts the chain to smaller pipe diameters. Centrifugal force centres the tool inside the pipe, so the entire inner circumference is cleaned.

As these chains are heavier than the lightweight versions, they are designed for 10mm and 12mm shafts. For 6mm and 8mm shafts we offer the lightweight plain chain knocker.
