Detailed Description

The RIDGID K-45AF Sink Machine is built for real service environments where speed, cleanliness, and control matter. The compact footprint and comfortable carry point make it easy to move between calls, up stairs, and through tight hallways. On site, the variable-speed motor delivers up to 600 RPM for efficient cleaning yet allows low-speed finesse around delicate fixtures and tight P-traps.

AUTOFEED® is the feature technicians appreciate most. With a single lever, you advance or retrieve cable without reversing the motor, reducing hand contact with rotating cable and minimizing splash. The two-piece twist-lock canister accepts an interchangeable inner drum, so you can pre-load different cable sizes and change over in seconds. The inner drum also improves water containment and reduces cable flip-over, which keeps the workflow smooth and the workspace cleaner.

RIDGID Inner Core cables (C-1IC, C-6IC, C-13IC, C-2IC, C-23IC) use a vinyl-wrapped core and compression-wound construction. The result is better push power through bends, strong resistance to kinking, and dependable cleaning at the cable end. The key benefit is fast, clean small-line clearing with precise speed control and simple cable management. This product is ideal for plumbers, facility maintenance teams, property managers, and restoration pros who need a reliable sink machine for everyday clogs.

Use Cases

• Residential service: Clear hair and soap buildup in bathroom sinks, tubs, and showers without removing fixtures.
• Commercial maintenance: Restore flow in office, school, and restaurant lavatories and break-room sinks with minimal disruption.
• Property management: Keep multi-unit kitchens and shared restrooms moving during tenant turnover and routine maintenance.
• Restoration and turnover: Open drains after renovation or cleanup when debris and residue restrict flow.

RIDGID K-45AF Sink Machine is ideal for 3/4–3 in small line cleaning where compact size, cleanliness, and quick cable changes are priorities.
