A Makita eccentric sander is suitable for professional sanding jobs. When you use a polishing disc on an eccentric sander from Makita instead of sandpaper, you can also use it to polish metal surfaces, like the car paint. There are models that work on the power grid or with a battery. When you choose for a Makita eccentric sander with 18V, chances are it's part of the Makita LXT battery platform. This means that you can use the batteries of this platform for other Makita tools with the same voltage as well.
