Rank #2 in Best Orbital Sander 2026: 10 Models Ranked — and the Amp Figures That Don't Add Up
DEWALT DWE6423-GB 280 W Random Orbit Sander, 125 mm
Price and rating as shown on Amazon when we collected them. Both change.
The DEWALT DWE6423-GB is a corded random orbit sander with a 280 W motor, a 125 mm hook and loop platen and a variable speed dial. The listing quotes an orbit rate of 8,000 to 12,000 opm, and the spec table puts the maximum rotational speed at 12,000 RPM. It takes second place in this guide at £90.50, rated 4.5 out of 5 across 651 ratings — 80 of those are five-star and six are one-star.
The number worth looking at is the amperage. This listing states 1.17 Amps at 240 Volts next to a 280 W motor, and here the two boxes agree: 280 divided by 240 comes to about 1.17. That is the opposite of the pattern running through this guide, where wattage has been tipped into the amp field and inflated by a factor of roughly 230. DEWALT is describing the tool it is actually selling, which is why the amp figure is worth reading on this page rather than ignoring. Everything below — the specs, the bullets, the review counts — is taken from the Amazon listing and not from any bench testing of our own.
