Proper pipe prep doesn't happen with one tool. It happens with the right combination of tools matched to what's in the pipe. T3's chain knocker and drill head lineup covers every level of cleaning and pe*******on.
Here's our complete chain knocker and drill head lineup, because not every pipe cleans the same way:
⚙️ Chain Knockers
For 2"–8" lines, compatible with 6mm–12mm cables. The reliable go-to for removing rust, dirt, and debris from pipe walls before lining.
⚙️ Chain Knockers with Drill Head
For 4" and 6" lines. One tool that sweeps the walls AND punches through blockages in a single pass.
⚙️ Circular Chain Knockers
For 3"–8" lines, 10mm or 12mm cable. Full circular contact for thorough, consistent wall coverage every time.
⚙️ Drill Heads
Pair with a centering device or chain knocker to aggressively take on roots, compacted debris, and hard reinstatements.
Right tool. Right pipe. Right prep. Which one are you reaching for most?
