Circular chain knockers

Renssi Chain Knocker Collection includes circular chain tools. These tools have a wide size range and their cleaning power is suitable for even larger pipes. Circular chain tools are available with sleeve and t-slide connectors and with no carbide bits feature. Without carbide bits, the cleaning power comes from carbide coating. Sleeve circular chain tools come with a SR securing ring, which ensures tool’s tight hold on the cable. What is the difference with circular chain tools from other chain knockers? It’s effective and there’s no place for errors in adjustments. Using circular chain tools is also a matter of taste - some of our customers prefer circular chain tools’ efficiency and ease of use.
