I use mine on a Dremel tool..Dremel makes them, also you can get them at Lowes, have to buy the adapter to attach it....they work really well... It is easy to use just run it over the rough spots cleans it up and you lose no detail, you can clean up a large project pretty fast with it...they come with instructions and what speed to use it at....Dremel's brush is a single brush you use alone, the ones from Foredom you have to attach 3 or 4 to your tool....I use the 3/4 inch...
