RUPES BigFoot LHR21ES Random Orbital Polisher (Ø150 mm / 21 mm orbit)

The RUPES BigFoot LHR21ES is an electric random orbital polisher characterized by its Ø21 mm orbit and Ø150 mm backing pad, designed for working large surface areas. RUPES states that the machine’s balance, combined with Ø150/180 mm foam polishing pads from the BigFoot range, delivers rapid cutting and an impeccable finish.

How the Random Orbital Movement Works

RUPES explains that the backing plate follows an orbit and is free to rotate about its own central axis. Rotation varies by centrifugal force and friction; if rotation is prevented, the motion becomes orbital-only. This random orbital action is described by RUPES as an excellent compromise between effectiveness and surface treatment quality.

Key Features & Controls

• Ergonomics & balance: RUPES highlights a perfectly balanced body, practical handgrip, silent operation, and minimum vibration.
• Antispinning shroud: dual function design to help protect the operator from moving parts and act as a clutch, preventing further stress on the foam pad when it’s not in direct contact with the surface.
• Electronic speed control module: speed controller on the handle; speed can be regulated during use without interrupting the polishing operation.
• On-off switch lock: locks the switch during polishing, allowing the operator to reposition hands while operating.
