Features moisture-resistant composite rotors, and premium counterweight bearings for long life and superior reliability.  Finishing Sanders can be converted to self-generated or central vacuum operation with the addition of a vacuum conversion kit.  Sanders come with a backup pad, pad wrench, and a bottle of air-tool oil.
