Sumake High Power Random Orbital Sanders come with either a 5 or 6-inch pad in both non-vacuum and vacuum models. With a free speed of 12,000 RPM and a 5mm orbit, these industrial sanders are leaders in the industry. Orbital Self-Vacuum Sanders produce their own vacuum used to capture dust in a localized bag. The central vacuum orbital sanders attach to a vacuum collection unit. Lastly, our non-vacuum orbital system does not have a collection system.
