The best random orbital sander for most people is the DEWALT DWE6423 — a variable-speed 5-inch sander that leaves a smooth, swirl-free finish. A random orbital sander strips old finish, smooths wood, and preps surfaces far faster than sanding by hand, and its random motion avoids the swirl marks a cheap sander leaves. Below are the best orbital sanders we’d actually run — every one confirmed in stock.

1DEWALT DWE6423 Variable-Speed 5″ Best overall
A 3-amp, 5-inch random-orbit sander with variable speed (8,000-12,000 OPM) so you can slow down for delicate finishing or speed up for stock removal, a low-profile body for control, and a dust-collection bag plus port. Smooth, comfortable, and swirl-free. The orbital sander most people should buy.
