Characterised by its large Ø21mm orbit and Ø150 mm RUPES backing pad, the electric LHR 21ES random orbital polisher is perrfect for working large surface areas. The perfectly balanced polisher, combined with the Ø150/180 mm foam polishing pads of the RUPES BigFoot range, guarantees rapid cutting and an impeccable finish._x000D_\n_x000D_\nRANDOM ORBITAL: the backing plate follows an orbit (the amplitude of which depends on the distance between the rotation axis of the drive shaft and the central axis of the backing plate) and is free to rotate about its own central axis. The backing plate is free to rotate at varying velocities and directions by effect of the centrifugal force of the offset movement and by effect of friction. Should the friction forces be such as to prevent rotation of the disc while the tool is still operating, the random orbital movement would simply become an orbital movement. The number of disc rotations is variable and independent of the number of orbits performed. The random orbital movement is at present the best compromise in terms of effectiveness and surface treatment quality._x000D_\n_x000D_\nELEGANTLY DESIGNED_x000D_\nThe RUPES R&D and Design departments have paid particular attention to the design and ergonomics of the BigFoot polishers. The perfectly balanced machine body, the practical handgrip, the silent operation and minimum vibration are just some of the characteristics that help make BigFoot the market’s most versatile and sought-after system._x000D_\n_x000D_\nANTISPINNING SHROUD_x000D_\nThe dual function antispinning shroud is designed to protect the operator against the moving parts and act as a clutch for the backing pad, preventing further stress on the foam polishing pad when it is not in direct contact with the surface._x000D_\n_x000D_\nELECTRONIC SPEED CONTROL MODULE_x000D_\nThe speed controller on the handle is both practical and easy to use. The speed of the polisher can also be regulated during use, thus avoiding any interruption of the polishing operation._x000D_\n_x000D_\nON-OFF SWITCH LOCK_x000D_\nPressing the button on the LEFT-hand side of the handgrip while polishing locks the on-off switch. This allows the operator to move his/her hands freely to different gripping positions while the tool is operating._x000D_\n_x000D_\nDESIGN_x000D_\nThe attention to detail is not limited to just the innovative and attractive design. The modern lines and exceptional technical quality are combined with a number of details that are the result of meticulous research aimed at achieving maximum operator comfort.
