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 had very high hopes for this tool. it cuts very well but is just flimsy the teeth get bent very easily. i was forest to throw it it the bin after the third use as it was so battered. the outer cutting ring needs to be made of thicker/stronger steel. the idea is perfect but sorry more a toy than a tool
