There are two versions of each kit available, 150mm and 180mm. If you have an LHR21 or an LK900E Mille with the larger backing plate you’ll want the 180mm kit. Those part codes will have the measurement of 180mm as a segment of the part code (i.e. – 9.COARSE180KIT). If you have an LHR15, LHR12E, or run the smaller backing plate on your LK900E Mille you’ll want to select a kit with the 150mm part code (i.e. – 9.COARSE150KIT).
All kit boxes will also include tool compatibility information printed on the exterior and your authorized RUPES distributor can assist you with choosing the right option for use with your polisher.
