Clean the inside of your pipe from wall to wall. These drain snakes have an end, called a chain knocker, that expands to fill your pipe as they rotate. Compared to drum-type drain snakes, 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-type drain snake. No special adapters are needed, just attach your drill to the hex shank on the case. While drum-type drain snakes can’t be used at the same time as an inspection camera, you can run a small camera next to these drain snakes to monitor your progress.

With a rechargeable battery included, these drain snakes give you a powered drain-snaking tool without having to attach a drill. They remove common bathroom blockages such as paper towels and baby wipes. The coiled cable head rotates to either break up clogs or grab onto them for retrieval. Since porcelain is prone to scratches, a rubber guard connects the cable and the drain snake body to prevent damage. These drain snakes can also remove clogs in floor traps and sinks. Also known as toilet and urinal augers.
