Rupes Bigfoot LHR15 Mark III Random Orbital PolisherBuilt to handle any detailing situation, the new LHR15 Mark III 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 LHR15 Mark III operates at a higher rpm compared to the LHR21 Mark III. This increased speed provides equivalent correction and does so with a pad diameter and orbit that are more conducive to curved or varied surfaces.
