The RIDGID K-750 Drum Machine (Model 47047) clears lateral lines with a 1/2 HP induction motor and AUTOFEED cable control, advancing and retrieving cable at up to 20 ft per minute. The corrosion-resistant drum holds 100′ of 3/4″ cable or 125′ of 5/8″ cable, and switching between the two takes no tools.
A single lever advances or retrieves the cable, so the operator isn’t feeding cable by hand while also managing the drum. At up to 20 ft per minute, AUTOFEED cuts the setup and retrieval time that adds up across a full day of service calls. The 200 RPM cable speed supplies the cutting action needed to get through roots, grease, and hardened deposits. Because the feed is mechanical rather than hand-fed, cable speed stays consistent from the first foot to the last, which matters when you’re working through a long lateral run and can’t afford the cable to bind or kink partway through.
The RIDGID K-750 runs either cable size without tools, and the right choice depends on the line, not just preference. 3/4″ cable holds up better against heavy roots and larger diameter lines, common on commercial laterals and older clay or cast iron pipe. 5/8″ cable is more maneuverable through tighter bends and smaller diameter residential lines, where the extra stiffness of 3/4″ cable can be harder to route. Many crews keep both spools on hand and swap based on the job rather than committing to one size permanently.
The 1/2 HP induction motor is built for sustained run time rather than short bursts. Unlike a universal motor, which wears faster under continuous load, an induction motor holds steady torque and temperature through longer jobs, which matters on a stubborn lateral line that takes ten or fifteen minutes of continuous running rather than a quick clear. That durability is also why the K-750 carries CSA approval to CSA and UL standards, the motor is built to hold up under exactly the kind of repeated, sustained commercial use that standard is meant to certify.
The drum resists dents and splitting under normal jobsite handling, and it wipes clean between calls instead of holding onto grease and debris. A wheeled design moves it through doorways and in and out of a service vehicle without a second person. The removable drum speeds up maintenance and cable swaps in the field rather than requiring a shop visit.

The K-750 ships with PVC drain cleaning gloves and an operator’s manual, so a crew can get it running on day one without ordering separate PPE.
The drum holds 100′ of 3/4″ cable or 125′ of 5/8″ cable. AUTOFEED adjusts to either size without tools.
Up to 20 ft (6 m) per minute, in both the advance and retrieve directions.
Yes. The 115V K-750 is CSA approved to CSA and UL standards.
PVC drain cleaning gloves and an operator’s manual ship with the K-750.
3/4″ cable handles heavier roots and larger commercial lines better. 5/8″ cable maneuvers more easily through tight bends and smaller residential lines. The K-750 switches between the two without tools, so many crews keep both on hand.
Pair the RIDGID K-750 with a RIDGID K9-204+ FlexShaft Machine for smaller-diameter lines, or browse RIDGID Drain Cleaning Equipment for the full lineup. The K-750 is certified to CSA and UL standards for North American use. Order from J.M. McKinney Co. for genuine RIDGID equipment, in-stock availability, and fast shipping.
