The K9-12 FlexShaft Drain Cleaning Machine is the smallest of the line of FlexShaft machines and perfect for residential use, eliminating the need to repeatedly unclog the same household drain lines. Clearing up to 30’ of 1 1/4-to 2” pipe, the K9-12 breaks up grease, hair and other soft blockages, making it ideal for kitchen and bath sinks, as well as tubs and shower drains. Powered by an 1800 to 2500 RPM cordless drill, the machine’s chain knocker expands inside the pipe to quickly clear the blockage and restore the pipe to full flow. A flexible, protective sheath encapsulates the cable, keeping it fully enclosed for less mess and faster cleanup. The built-in clutch design also extends the cable life.
