If you do auto body work, woodworking, or even drywall sanding, this Campbell Hausfeld 'Jitterbug' air sander is a classic tool. It's a small, palm-grip orbital sander that runs at 8,000 strokes per minute. The orbital action helps prevent swirl marks, giving you a nice, smooth finish on flat surfaces. It uses standard sanding sheets (either sticky-back or plain) that are held on by spring-loaded clamps, so changing paper is quick. There's a built-in regulator right on the tool so you can dial down the speed for more control. The trigger is easy to operate with one hand. It's lightweight and easy to maneuver into tight spots. Just hook it up to your air compressor (check your PSI requirements), pick your grit, and go. A reliable, no-frills sander for detail work and finishing touches.
