Chain knocker with male coupling 16mm T-slot (5/8"), cam chains

This special version of the chain knocker with cam chains from rak has a double 16mm T-Nut coupling: at the top of the chain knocker there is a 16mm pin coupling. The chain head can thus be used in combination with a drain cable tool, thus extending its range of application even further! For example, a carbide miller or a hardened sawtooth blade auger can be coupled, which first drills blockages. Then the pipe walls are directly machined and cleaned with a chain knocker.

You would like to increase your efficiency in drain cleaning with chain knockers over longer distances? Then simply couple two chain chain knockers directly behind each other with the help of this chain knocker design! This way you increase the efficiency by 100% and save valuable time.

The chain knocker with 16mm male coupling is available in all versions, i.e. with smooth chains, cam chains or chains with carbide facing.

chain knockers are an indispensable tool for every end pipe cleaning in pipes. The cam chains are designed for stoneware and concrete pipes, and the sturdy chains are welded to the head and to the coupling. They can be completely replaced (re-welded). Worn parts can therefore be renewed individually instead of replacing the whole tool. The chains are available from us as spare parts. The chain knockers should always be used only with reinforced drain cleaning cables (S-spirals, S-SMK-spirals).
