Achieve a Flawless Finish with Ultimate Cordless Control and Power

Experience the perfect balance of power and precision with the Bosch GEX18V-5B15 18V Brushless 5 In. Random Orbit Sander Kit. Engineered for the professional woodworker and carpenter, this tool features a high-efficiency brushless motor that delivers stock removal comparable to a corded sander, but with the freedom of the AMPShare™ cordless system. The kit includes a high-performance CORE18V 4Ah battery, utilizing advanced 21700 cell technology to provide extended runtime and consistent power, allowing you to tackle large surfaces without being tethered to a wall outlet.

Designed for comfort during extended use, the GEX18V-5 features an ergonomic palm-grip design that positions your hand close to the workpiece for superior control and stability. The integrated vibration dampening element significantly minimizes user fatigue, while the soft-start technology ensures a smooth ramp-up to prevent gouging on delicate surfaces. Whether you are smoothing rough stock or preparing a surface for a final coat, the speed selector allows you to match the orbits per minute (OPM) to the specific material. Coupled with a versatile dust collection system compatible with bags or vacuum hoses, this sander ensures a cleaner, safer work environment.

Key Features

  • Cordless Powerhouse: Brushless motor technology delivers material removal rates similar to corded sanders for heavy-duty applications.
  • Superior Ergonomics: Well-balanced palm-grip design keeps your hand close to the work material to avoid tilting and pressing down.
  • Variable Speed Control: Adjustable speed selector (6,000 - 10,000 OPM) provides optimal results across different materials and finishing tasks.
  • Vibration Control: Built-in dampening element reduces vibration transfer to the hand, minimizing fatigue during long sanding sessions.
  • Dust Management: Features a 5-inch 8-hole sanding pad for optimal extraction; includes a dust bag and is compatible with vacuum hoses.
  • Soft-Start Technology: Reduces startup torque to ease into the workpiece, preventing initial swirl marks or damage.
  • CORE18V Battery: Includes a 4Ah Advanced Power Battery with CoolPack technology for longer life and efficient power management.
  • Flexible Pad System: The hook-and-loop backing pad conforms to many contours, making it ideal for flat, concave, and convex surfaces.
