Description Reviews The MarkIII incorporates many of the new features, first shown on the LK900E Mille, and interesting design updates, that make one of the industries best polishing system even better. The highly efficient motor of the MarkIII BigFoot Random Orbital Polisher produces a speed range of 3000 to 4500 for the 21mm models and 3000 to 5200 for the 15mm models. The specially engineered and custom wound motor, created in-house by RUPES, generates high levels of torque while requiring just 500 watts of input. This results in RUPES offering the most efficient motor in random orbital polishing today. With its 21mm orbit and its Ø150mm backing pad, the LHR 21 MarkIII random orbital polisher is the perfect tool for working large surface areas. The LHR 21 MarkIII allows the operator to achieve ultra-high quality finishes, even with limited passes. Improved efficiency guarantees more power and torque on every surface. NEW IMPROVEMENTS: -New ergonomic grip on the polisher head -New rubber stand on the topside of the body for balanced resting of the polisher when not in use -New pressure sensitive trigger with progressive acceleration -New 9 meter long power cord -New white design cues Ø max polishing pad 180mm Weight 2,25kg Ø backing pad 150mm-6" R.P.M. 2500-4700 Ø orbit 21mm-13/16"
