Circular Chain Knocker (With Hard Metal Tips)
£78.00
Excluding Sales Tax
💥Built for aggressive cleaning and descaling, this Circular Chain Knocker features fused carbide-tipped chain links for rapid removal of tough deposits and obstructions.
The highly abrasive carbide tips make quick work of:
🪨 Lime scale
🚽 Urine scale
🧱 Cement and tile grout
🌱 Root intrusions
⚠️ Due to the aggressive nature of the carbide teeth, this tool is not suitable for PVC (ABS) pipework.
🔄 Full Circumference Cleaning
As the chain rotates, centrifugal force drives the links evenly against the pipe wall, allowing the tool to clean around the entire internal circumference of the pipe.
Unlike conventional chain knockers that strike individual points, the circular design spreads the cleaning action more evenly across the pipe surface for fast, consistent results 🎯.
🛠️ Ideal for Liner Removal
When paired with a drill head or mole tool, this chain becomes an effective solution for grinding away failed liners and removing excess cured liner material.
