Compact Cordless Orbital Sander for Precision Finishing, Detail Sanding, and Dust-Free Surface Prep

The Bosch GSS12V-40N 12V Max Orbital Finishing Sander delivers powerful cordless performance in a compact, ergonomic design. Built for precision and control, this sander features a balanced grip that keeps your hand close to the workpiece, making it ideal for fine finishing, edge sanding, and tight-area detail work. The brushless motor provides corded-like power and extended runtime, while the variable-speed dial (6,000–10,000 OPM) allows you to match speed to material and application. Whether you're prepping wood, smoothing surfaces, or refining corners, this tool offers the versatility and mobility professionals demand.

Designed for flexibility, the GSS12V-40N includes interchangeable sanding plates for 1/4 sheet, 1/3 sheet, and detail sanding. The hook-and-loop backing pad conforms to contours, and soft-start technology ensures smooth engagement with the workpiece. Dust management is built-in with a mobile dust bag and vacuum hose interface for cleaner operation. With constant speed under load and an easy-to-reach on/off switch, this orbital sander is a must-have for cabinetry, furniture finishing, and jobsite touch-ups. **Battery and charger sold separately.**
