The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Context, not marks against it, and our read of the data, not a lab test.
Overview
The DEWALT DWE402 runs on 120V corded power with a 1,320-watt motor spinning at 11,000 RPM. At 6 pounds, it is the heaviest corded model in this batch, and that weight reflects the larger motor driving its class-leading wattage output. Priced at $94, it delivers the best power-to-dollar ratio among all corded grinders here.
With 1,000 monthly buyers and 5,400 total reviews at 4.8 stars, the DWE402 leads the batch by every demand and quality metric for corded tools. Its combination of the highest review count, tied-for-most monthly purchases with the DWE4011, and top-tier 4.8-star rating makes it the corded angle grinder benchmark in this category.
The 1,320-watt motor is 55 percent more powerful than the DWE4011 at 850 watts and 15 percent more powerful than the DWE4120N at 1,140 watts. Buyers doing heavy metalwork, thick plate cutting, or professional grinding tasks will feel that difference in sustained cutting performance. The 6-pound weight is the only real tradeoff for users prioritizing lighter tools.

Performance notes
Corded electric on 120V, 1,320-watt motor, 11,000 RPM no-load speed, 6 pounds.

Frequently asked questions
How does the DEWALT DWE402 compare to the DEWALT DWE4011?
The DWE4011 is $5 cheaper at $89, offers a higher 12,000 RPM speed, and weighs 3.9 pounds versus 6 pounds for the DWE402. The DWE402 delivers far more power at 1,320 watts versus 850 watts. Choose the DWE402 for heavy-duty work; choose the DWE4011 for a lighter, faster-spinning all-rounder.
What disc size does the DEWALT DWE402 use?
The published specs do not list a disc diameter. Based on its positioning in the 4.5-inch angle grinder category, standard 4.5-inch abrasive and diamond discs should be compatible. Verify in the product listing before purchasing accessories.
Is the DEWALT DWE402 worth buying over lower-wattage DEWALT models?
For light to medium tasks, lower-wattage options like the DWE4011 are fully capable and easier to handle. If you regularly do heavy grinding, thick plate cutting, or professional metal fabrication, the extra 470 watts over the DWE4011 and the 200-plus watts over the DWE4120N at $84 make a real difference.
