6" and Up

Random orbit sanders are used to strip paint off furniture, prepare new molding, clean up between finish coats, and smooth and clean metal and composite materials such as solid-surface countertops. Random orbit sanders have a unique double motion: the sandpaper disc spins in a circle while the whole pad moves in an oval loop which results in a swirl-free finish even when sanding across the grain. Random-orbits work more quickly than vibrating sanders but don't remove as much material. For that type of work see: belt sanders for flat surfaces, disc sanders for curved ones. When choosing a random-orbit sander, look for a motor size, body configuration, and pad size (5- or 6-inch) that fits your work. Be sure the random orbit sander you choose has a dust collection attachment option.
