Chain knocker with carbide drill head and spikes, 22mm T-slot (7/8")

The chain knocker with integrated drill head from Seweri has been developed for the toughest applications in drain cleaning. With this special drain cable tool, you can simultaneously drill out a pipe blockage in the direction of flow and remove the hardest incrustations and deposits on the pipe wall. With this tool you have combined two work steps in one. The tip of the tool is equipped with extremely hard carbide tungsten carbide. Furthermore, the chain knocker has 3 chains, which are fitted with carbide. These carbide spikes destroy even very hard incrustations like urine scale, lime and concrete. For renovation purposes the surfaces of the pipes can be roughened. The length of the chains is adjusted to different pipe diameters in order to clean optimally without damaging the pipes.

The chain head has a 25mm diameter carbide tip and a 22mm T-Nut coupling for connection to drain cables from ROWO, rak, ROTHENBERGER, REMS, RIDGID, E&R and other premium manufacturers. All versions have 3 chains with carbide spikes. The chains have different lengths for pipe diameter 100mm, 150mm and 200mm. The diameter of the chain links is 4mm.
