Clean the inside of your pipe from wall to wall. These drain cleaners have an end, called a chain knocker, that expands to fill your pipe as they rotate. Compared to drum-style cleaners, they knock gunk off the side of pipe walls better. Use them in any pipe material on soft blockages, such as grease buildup. They can also be used on toilets and urinals without damaging the porcelain finish because the cable is enclosed in a shaft. A flexible nylon shaft covers the cable to control its movement and prevents waste from splattering as the cable spins in the drain—keeping the surrounded area cleaner than when using a drum-style cleaner. No special adapters are needed, just attach your drill to the hex shank on the case. While drum-style cleaners can’t be used at the same time as an inspection camera, you can run a small camera next to these drain cleaners to monitor your progress.

Add chain knockers in different sizes to clear pipes of various diameters. Use carbide-tipped chain knockers to remove scale and tree roots from hard walled pipes.

Add a drop head to navigate through tight turns while dropping down vertical vent stacks. Add a penetrating head to work through tough blockages, such as wet wipes.

Shaft lubricants help these drain cleaners slide down pipes, especially when working on long runs of pipe. Apply them with a towel to the outside of the shaft.
