Overview
Eleven thousand RPM and a 1,320-watt motor put the DEWALT DWE402W in the corded angle grinder class, running on 120-volt AC/DC power and weighing 6 pounds with a footprint of about 15 by 6 by 4 inches.
At 11,000 RPM and 1,320 watts, this sits in DEWALT's small-angle-grinder class built for cutting, grinding and surface prep rather than heavy material removal, where larger grinders with bigger wheel diameters take over. Being corded rather than battery powered, it trades portability for sustained power without needing a battery swap mid-job. The W in the model name commonly marks a kit version bundled with grinding wheels.
- Power: 120V AC/DC corded

Who it's for
Fits a tradesperson or DIYer doing metal cutting, weld cleanup or surface grinding who wants sustained corded power rather than battery runtime limits. Less suited to someone working far from an outlet who needs a cordless grinder instead.
Strengths and trade-offs

- 1,320-watt motor at 11,000 RPM
- Corded AC/DC power avoids battery runtime limits
- 4.7 rating across 566 reviews
- 100 units bought in the past month

Performance notes
The 1,320-watt motor spinning at 11,000 RPM gives it enough sustained power for cutting and grinding metal without the runtime limits of a battery, since it draws directly from a 120-volt AC/DC outlet. At 6 pounds and roughly 15 inches long, it stays maneuverable for one-handed use across most grinding and cutting tasks.
