The RIDGID K9-12 is the most compact version of the FlexShaft® Drain Cleaning Machines. The fully enclosed housing contains 30' of FlexShaft cable, encapsulated in nylon sheath for less mess and easy cleanup. The lightweight, portable design is perfect for 1 1/4" - 2" pipes. FlexShaft cable is spun by attaching your cordless drill to the input shaft on the housing. As the cable spins, the chain knocker attached will expand to provide wall-to-wall pipe cleaning. Fast setup and cleanup, quick cleaning, and cordless convenience allow you to restore your pipes to full flow capacity as efficiently as possible.
