70 ft (21.3 m) of 5/16-in. FlexShaft cable in a tough nylon sheath
Wall-to-wall chain knocker clears blockages and restores full pipe flow
Powered by any standard 1800–2500 RPM cordless drill
Perimeter latches make opening the drum easy; cable clamp protects the cable

RIDGID K9-204+ Drill Requirements
Use a cordless drill rated at 1800–2500 RPM. Insert the drill into the drive socket, lock the housing, and feed the cable into the pipe. The drill supplies the rotation; the FlexShaft cable follows curves and keeps moving through the line.
Chain Knocker Selection and Setup
The included chain knocker expands inside the pipe to scour the walls. For tougher roots or scale, swap in a carbide chain. The machine accepts the full range of RIDGID FlexShaft heads, so you can match the cutter to the blockage.
Features
Wall-to-wall cleaning in 2" to 4" pipe with 70 ft of 5/16-in. FlexShaft cable
Chain knocker scours pipe walls and clears blockages to restore full flow
Power with any standard 1800–2500 RPM cordless drill for portable operation
Upgraded latches, improved cable clamp, and on-board hex key storage simplify service
The FlexShaft K9-204+ is built to spend less time on setup and more time clearing the line. Perimeter latches give you quick access to the drum, while the improved cable clamp protects the cable at the point where it exits the housing.
Pick the Right Head
Use the included chain knocker for routine blockages and grease buildup. Switch to a carbide chain for roots or hard scale, or use a penetrating head to get through tough debris before switching to the chain knocker for a wall-to-wall finish.
Power Where You Need It
With any standard 1800–2500 RPM cordless drill, you can operate this machine without a separate motor or generator. That makes it easier to work in tight basements, crawl spaces, and outside commercial locations.

A plumber's best friend
I've been a plumber for over 40 years and I've used every kind of drain machine. The FlexShaft K9-204+ is a whole different animal. It's lightweight and hooks up to my cordless drill, so I don't have to drag a big motor down the stairs. The 70 feet of cable is plenty for most residential lines. The chain knocker really tears through roots and sludge. It flexes around bends without kinking. It's a bit tricky to get the hang of feeding it, but once you do, it saves a ton of time. I'd recommend it for any plumber who needs a quick solution.

Saved us money on plumber calls
I own a property management company and we have constant drain issues. This FlexShaft has saved us a lot of money on plumber calls. It's easy to set up and the 70-foot cable reaches most clogs. I pair it with a high-torque drill and it powers through. The chain knocker is aggressive but effective. It can be a bit messy, so wear gloves. I've used it about ten times now and it's held up well. Definitely a must-have for any handyman.
