Quick-change Roloc Discs are a welder's best friend due to the infrequent maintenance and easy, device-free changing system. They are also perfect for getting into smaller areas as our quick change Roloc discs come in sizes of 2 and 3 inches as well as 36, 50, 80, and 100 grit. Non-Roloc surface conditioning discs are supplied in 2 and 3 inches as well, but specify fine, medium, or coarse for grit type. Roloc back up pads are also offered for both sizes so that you can properly mount your disc on a grinder. Your welding and fabrication projects are already laborious enough. Make it easier on you and shop our quick-change surface conditioning discs!
