We’re constantly using orbital sanders at work and at home, testing them, evaluating them, and getting feedback from users. Put a 40-grit disc on the tool and it acts as a grinder apply a 400-grit disc and it’s a polisher. The tool strips rust, cleans up flea market finds, and acts as a power file to take the sharp edge off a freshly-cut piece of metal. Use these power tools to strip paint or sand the gloss off a painted surface to prepare it for the next coat.
But they do a lot more than just that and in the process become a versatile workshop staple. Orbital sanders are primarily wood-smoothing tools.
