Heavy-duty X-Tip chain knocker with carbide, for cast iron, clay and metal pipe, optional drill head, for flexible shaft

This heavy-duty X-Tip chain knocker is our most aggressive chain. It is designed for removing roots, scale, tuberculation, cement and failed liners in metal, cast iron and ceramic pipes.

This chain is not suitable for PVC pipes – it will damage the pipe wall within a short time. For PVC we offer plain chains without carbide bits.

Cutting action

The chain links are 4mm thick. The added weight provides the cutting performance against stubborn deposits. The X-shaped carbide teeth act like blades, scouring the inner pipe wall, while centrifugal force keeps the tool centred inside the pipe.

Optional drill head

The chain is available with or without a drill head. The drill head has a crown shape and therefore cuts particularly aggressively in the forward direction. It is angled so that it can pass a 90-degree bend – proceed carefully there, as it cuts strongly in bends too. If you want to protect the pipe wall in tight bends, use the chain without a drill head.

Construction

All versions contain three individual stainless steel chains of varying lengths. The hubs let you adjust the chain: spreading them further apart on the shaft lets you clean smaller pipe diameters as well. It is mounted to the flexible shaft with set screws.

Technical data

• Pipe diameter: 75mm, 100mm, 150mm, 200mm
• Fits shafts: 8mm, 10mm, 12mm
• Chain links: 4mm thick
• Cutting elements: X-shaped carbide teeth
• Structure: three individual chains per set, adjustable
• Material: stainless steel
• Optional: crown drill head at the front

Use

• Select the chain according to pipe diameter and shaft thickness
• Fit it to the flexible shaft with the set screws
• Insert it into the pipe and increase the speed gradually
• Let it break down roots, scale or hardened blockages
• Work under control and avoid excessive force, especially in bends
• Flush the pipe thoroughly after cleaning

We recommend using it on a 10mm or 12mm shaft so that enough torque is available for the heavy chain. For the 8mm shaft we offer the lightweight version of the X-Tip chain.

That makes the chain suitable for the Picote Super Midi, Maxi Miller and Midi Cleaner, which use heavy-duty shafts of 10mm or 12mm.

For particularly solid blockages the chain can be wound around the shaft so that it forms a point and bores into the blockage.
