Bosch GEX18V-5N 18V Brushless 5" Cordless Variable-Speed Random Orbit Sander

The Bosch GEX18V-5N 18-volt brushless 5-inch random orbit sander strips, smooths, and finishes wood panels, cabinetry, and architectural millwork with corded-equivalent material removal rates. Engineered with a compact ergonomic palm grip that positions your hand close to the workpiece to eliminate tilting and surface gouging, this cordless finishing sander features a high-efficiency brushless motor and an adjustable variable-speed dial ranging from 6,000 to 10,000 OPM. Outfitted with constant-speed circuitry maintaining RPM under heavy load, soft-start technology minimizing startup kick, integrated vibration dampening to reduce hand fatigue, an 8-hole backing pad for efficient dust extraction, and bare-tool compatibility, it equips finish carpenters, cabinetmakers, and woodworkers with precise surface preparation control. **Battery and charger sold separately.

Best Used For:

  • Cabinetry and Millwork Surface Finishing: Sanding hardwood doors, face frames, and edge profiles smooth prior to staining, painting, or final clear-coat application.
  • Furniture Restoration and Stock Removal: Stripping old varnish, paint, and surface blemishes off tables and chairs quickly using the 10,000 OPM high-speed setting.
  • Jobsite Trim and Fine Woodworking: Smoothing miter joints and flush-sanding installed trim and molding where cord-free maneuverability is essential.

Key Performance & Safety Features

  • High-Performance Brushless Motor: Delivers stock removal rates comparable to corded sanders while maximizing runtime efficiency on 18V battery platforms.
  • Variable Speed Dial (6,000–10,000 OPM): Allows operators to match oscillation speed precisely to the workpiece material, preventing burn marks on delicate veneers.
  • Ergonomic Low-Profile Palm Grip: Centers downward pressure directly over the 5-inch pad to prevent tipping and ensure an evenly flattened surface finish.
  • Soft-Start Circuitry: Gently ramps up motor speed upon trigger engagement to eliminate initial surface gouging and control kickback.
  • Constant Speed Under Load: Automatically applies electronic power adjustments to maintain consistent oscillation speed during aggressive stock removal.
  • Advanced Vibration Dampening: Integrated isolation elements minimize jarring vibrations transferred to the palm, enabling comfortable all-day sanding operations.

Pro-Tip: When sanding fine hardwood veneers or soft pine, dial the variable speed selector down to around 6,000 OPM and let the weight of the sander do the work; pressing down hard generates excess friction that can clog paper or burn delicate wood grains.
