Always nice to have one these around a Plumbing Snake 12 Auger worm drive drill at the end of the 50 feet in length line. Do not need it anymore. Easy to operate just put the handle on the end of the snake and disconnect your trap insert it and twist. S. You can go out to your local hardware store and buy the attachment pretty cheap set like 8 for 10.00. I have a smaller one blue 25 ft. take little, spinning smaller Auger drill end that is 14 15.00 offer accepted.
