Rupes Random Orbital Polisher - Bigfoot LHR15 Mark III

Built to handle any detailing situation, the new LHR 15 MarkIII is the new frontier of detailing. The ergonomic design allows for precise paint correction with complete comfort, in curved surfaces and difficult to reach areas. The LHR 15 MarkIII operates at a higher rpm compared to the LHR21 MarkIII. This increased speed provides equivalent correction and does so with a pad diameter and orbit that are more conducive to curved or varied surfaces. RANDOM 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.
