RIDGID FlexShaft K9-12 Wall-to-Wall Drain Cleaning Machine

The RIDGID K9-12 FlexShaft is a compact, lightweight professional drain-cleaning machine designed for cleaning 1-1/4" to 2" (32–50 mm) drain pipes. It uses a flexible 1/4" (6 mm) cable enclosed in a durable nylon sheath and housing to reduce mess and simplify cleanup.

The cable is driven by a compatible cordless drill connected to the machine's input shaft. As the cable rotates, the chain knocker expands against the inside wall of the pipe, providing wall-to-wall cleaning to break up grease, sludge, hair, soft buildup and other light residential blockages.

Its compact design makes it particularly suitable for sinks, tubs, showers, kitchen drains and other small residential drain lines. The integrated clutch helps protect the cable and extend cable service life.

Key Features & Advantages

1. Wall-to-Wall Cleaning
The chain knocker expands inside the pipe to contact the pipe wall, providing more complete cleaning than simply pushing a conventional cable through the blockage.

2. Compact and Lightweight
At approximately 3.8 kg, the K9-12 is substantially easier to transport and position than larger drain-cleaning machines.

3. Less Mess
The cable is enclosed in a nylon sheath and housing, helping contain debris and making cleanup easier.

4. Cable Protection
An integrated clutch helps protect the flexible cable if the chain knocker encounters resistance or stops rotating.

5. Cordless Operation
A suitable cordless drill provides the drive power, allowing the machine to be used where electrical power is inconvenient.

6. Multiple Accessories
The K9-12 can accommodate smooth chain knockers, carbide-tipped chain knockers, penetrating heads and brushes for different cleaning requirements.
