Are you ever on the job sanding, and find yourself going back and forth between a belt and disc sander? The belt is perfect for high-speed, get-it-done-quickly sanding, while the disc is more suited for polishing, working, and shaping. It's a pain to switch between them constantly! Well no more. Check out a combination disc & belt sander, and have both at your disposal. Work from one to another without ever having to turn off your machine.
