Meet the BOSCH GSS20-40 1/4-Sheet Orbital Finishing Sander — a compact, finish-focused tool built for pros and serious DIYers who want smooth, uniform results with minimal fatigue.

Powered by a beefy 2.0 Amp motor that delivers up to 12,000 oscillations per minute (OPM), this sander machines through finishes on a variety of surfaces with steady, even results.
