Bosch Professional GEX 185-LI 18 V Cordless Random-Orbit Sander, 125 mm

Bosch Professional GEX 185-LI 18V Random-Orbit Sander, 125 mm is a cordless tool for sanding wood, painted surfaces, filler, and plaster. The brushless motor operates at no-load speeds from 6,000 to 10,000 RPM. Speed preselection allows the sanding action to be adjusted for surface preparation, material removal, or finishing. At full speed, the oscillation rate reaches 20,000 OPM, with a minimum setting of 12,000 OPM. This range allows control across different materials and stages of a sanding task.

Integrated dust extraction feeds debris into the supplied dust bag, helping to limit loose dust around the work area. Abrasives attach to the round sanding plate using a hook-and-loop fastening system. Weighing 930 g, the cordless random-orbit sander combines a compact body with an ergonomic soft-grip area for one-handed operation. An 18 V, 4 Ah battery is included for cordless use around workshops or job sites. No battery charger or sanding discs are supplied, so these items need to be sourced separately.
