The Fein MultiMaster 9-26-02-081-01-0 Dust Free Sanding Kit extracts dust directly through the perforated sanding pad and paper. Dust Free Sanding makes sense. Sanding is faster and creates a better finish because the sandpaper rides directly on the work surface, instead of sanding through a layer of dust. Eliminate exposure to harmful dust, and reduce clean-up chores by up to 90% when sanding.
