Overview
Cordless and running on Bosch's 18 volt platform, the GEX18V-5N is a random orbit sander spinning up to 10,000 RPM. It weighs 2.4 pounds, measures 8.8 by 6 by 4.3 inches, and holds a 4.7 star rating from 630 reviewers.
Cordless power tools ordinarily trade some outright output for freedom from a cord, and the GEX18V-5N carries that tradeoff into a compact 2.4 pound body built for one-handed control on trim, furniture and detail work. The 10,000 RPM top speed and 18 volt Bosch battery platform make it a natural fit for anyone already invested in Bosch's 18V tool lineup.

Who it's for
Woodworkers and DIYers who already own Bosch 18V batteries and want a lightweight sander for finish work without dragging a cord around. It suits detail sanding and touch up more than heavy stock removal on large flat panels.
Strengths and trade-offs
Drawn from this product's published specifications.
- Runs on Bosch's shared 18V battery platform

- 4.7 rating from 630 reviewers

Performance notes
The motor turns up to 10,000 RPM, a competitive top speed for a cordless random orbit sander that should keep pace with corded models on light to medium sanding tasks. At 2.4 pounds and roughly 9 inches long, the tool is light enough for extended one-handed use, though cordless sanders generally see output taper as the battery drains.
