I don't know exactly how fast - = experiment on a few junk keys and you'll get a feel for it real quick. = Make a few scratches on some junk keys and you will find out how = aggressive a fast buffing wheel can be! With just a few minutes of = practice to gauge your rpms, you will be able to do fast beautiful = buffing with your ShopSmith. I have purchased all my buffing supplies = from Pianotek and have been very pleased with their products.

(All those little scratches that will = always be on a set of plastic keys after a few years will buff out = perfectly in seconds!).
