Review on Dynabrade 56819 Dynorbital Supreme Orbital by Simo Ramsey

They use a lot of CFM but do a much better job than any electric grinder I've ever used. Dust collection is amazing and all that is needed is a vacuum cleaner. It comes with a PSA seal, but you can order a velcro here at Revain. I've been using Sioux for years but it's getting harder and harder to find. It's at least as good. My Festool, Bosch, and Porter cord grinders sit on the shelf unless I need a square pad to get into a corner.
