With DEWALT sheet sanders, you can sand large, flat surfaces like tables, doors, and stairs. You attach the sandpaper with a clamp or velcro. That way, you can decide what suits your job best. You also receive a dust bag, so your workplace remains clean. Does the sheet sander have a variable speed? You can adjust it to the job for the best result. With a constant speed, you don't lose power when there's a lot of resistance. The DEWALT cordless sheet sanders are part of the DEWALT XR 18V battery platform.
