BigFoot LHR21 Mark V Random Orbital Polisher

The RUPES BigFoot LHR21 Mark V Random Orbital Polisher, Part #LHR21V/US/STD, is a professional long-throw polisher engineered for rapid paint correction, efficient surface coverage, and exceptional finishing performance. Featuring a 21mm orbit and a 150mm (6-inch) PrecisionPro backing plate, the LHR21 Mark V is ideal for polishing large automotive panels, boat hulls, RVs, and other expansive surfaces.

The Mark V introduces advanced POLYSYNTHEC composite gears, which are lighter than traditional metal gears and require less lubrication. This innovative gear system improves motor efficiency while significantly reducing noise and vibration, providing smoother operation, better control, and greater comfort during extended polishing sessions. RUPES reports a 47% reduction in operating noise compared with previous models.

A redesigned low center of gravity positions the tool 13mm lower than previous models, increasing stability and helping the operator maintain precise control across flat, curved, and complex surfaces. The included PrecisionPro backing plate features an optimized balance and a protective rubber edge to help reduce the risk of accidental contact with delicate edges and adjacent surfaces.

Powered by a 500-watt motor, the LHR21 Mark V operates between 3,000 and 4,500 RPM. Its electronic speed control allows the operator to adjust polishing performance for compounding, defect removal, refinement, and final finishing applications. The extra-long 30-foot electrical cord provides excellent mobility around vehicles and boats without frequent repositioning.
