Thanks to its 21mm orbit and its Ø150mm backing pad, the LHR 21 MarkIII random orbital polisher is the perfect tool for working large surface areas. Even with limited passes, the LHR 21 MarkIII allows the operator to achieve ultra-high quality finishes. The rubberized front grip of the MarkIII offers exceptional comfort for the operator while providing a non-slip surface for control. The new electronic speed control dial allows for easy adjustment of the top speed of the polisher without requiring the operator to move his hands. The larger dial is easily adjusted with a move of the thumb.  Other features include 9 meter electrical cord and a progressive trigger.  TECHNICAL DATA Ø backing pad (mm/in) 150 – 6″ Ø orbit (mm/in) 21-13/16” Power (W) 500 R.P.M. 3000 – 4500 Weight (Kg/lbs) 2,7 – 5,95 Speed control • Backing pad thread M8-F Electrical Cord (m/ft) 9 – 30’
