Turn your Dremel rotary tool into a versatile sanding machine with the 504 3/16 In. (4.8 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 504 features a medium 80 grit abrasive, perfect for sanding bare wood to prepare it for removing varnish and final finishing.
