A compact, effective random orbit sander that leaves a smooth, swirl-free finish on wood and other surfaces. Well suited to fine sanding, paint removal and finishing work on small and medium projects. A 2.5 mm oscillating action removes material quickly. The built-in dust extraction keeps the work area clean, and the hook-and-loop pad changes sanding sheets in seconds. The switch carries a rubber seal to keep dirt and dust out. Battery system: ONE+ is Ryobi's 18V platform — one battery fits over 200 tools for house, garden, car care, craft and hobby. Battery and charger are not included.
