Chain knocker "flexible" with carbide spikes for Rioned Allround

This chain knocker for the 16mm drain cable of the Rioned  Allround drain cleaning machine impresses with its high flexibility. The thin spring core in combination with the fine chain links make it possible to work in pipes with blockages from 50mm diameter. The chain knocker is extremely flexible and can be easily guided through bends.
The rounded blade at the tip of the chain knocker has the advantage that it can also be used to a certain extent as a drilling tool at drain cleaning. At the same time, it serves as a suspension for the carbide chains.
chain knockers are one of the most important drain cable tools. They are used to remove incrustations and deposits on the pipe walls. The rotation of the tool tensions the chains, centers the tool in the pipe and attaches itself to the pipe wall. The chain knockers with carbide spikes are suitable for the most stubborn, solid deposits.
