I've got multiple sanders and a heavy duty 7" polisher, none of which do any dust extraction. I'm already convinced of the value of Festool dust extraction, especially in my small workshop. What I'm hoping is to get a Rotex to do double-duty as a woodworking sander, as well as removing oxidation on a fiberglass boat in areas too tight for the polisher. Will these things do all this, and if so, any advice on which one?
