Turn your Dremel rotary tool into a versatile sanding machine with the 502 3/8 In. (9.5 mm) 80 Grit Flapwheel. Flapwheels work well for gentle paint or rust removal, light material clean up, and polishing flat or contoured surfaces. They're effective as a finishing sander after heavier surface sanding and material removal is completed. The 502 features a medium 80 grit, perfect for sanding bare wood to prepare it for removing varnish and final finishing.
