Crown Root Cutters are quite an aggressive rotational tool for cutting through more stubborn roots and will also clear fat and grease build up of the walls of drains and sewers.

I found this a pretty sturdy bit of kit. It fitted onto my rods without any problem (worth checking carefully as I think there are different types of drain rods). I sharpened the blades as I though that would help and with the handle I bought separately I was able to operate it as a cutter. Need to be careful with bends in the drain as it could get stuck. Minimum fee for a drain specialist was £90 so I thought the investment was worth it. Unfortunately I have not so far been able to cut through the blockage but I don't think that is the fault of the cutter. It maybe that the cutter has cut around it and it now rotating around the central part of the blockage which remains.
