The Rupes RH356A Skorpio III is the most popular sander in the Skorpio III range — and for good reason. The 6mm orbit delivers the perfect balance between material removal speed and surface finish quality, making it the most versatile option in the lineup. From flatting body filler and primer surfacer to knocking back orange peel and stepping down through clear coat grits, the RH356A handles the full spectrum of automotive sanding tasks with consistent, controllable results.
Whether you're a bodyshop running production volume or a detailer tackling a full paint correction prep, the 6mm is the orbit that handles P120 through P500+ and delivers the results professionals rely on. It's the all-rounder that earns its place as the first sander most reach for.
