Use your Makita eccentric sander for quick and thorough sanding of large surfaces. When you attach a polishing disc to the Makita eccentric sander instead of sandpaper, you can also use it to polish metal surfaces, such as the paint on your car. Makita has different types of eccentric sanders, namely battery or electricity. Some eccentric sanders are part of the Makita battery platform. This allows you to exchange batteries of the same brand and platform with other Makita (garden) power tools.
