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 DWE402W delivers 11000 RPM from a 120V AC/DC corded motor rated at 1320 watts. At 6 pounds and measuring 15 inches long by 6 inches wide, it is built for sustained work rather than tight-space access. Based on specs and verified owner reviews, this grinder handles demanding material removal, weld cleanup, and cutting tasks without hesitation.
At $105.98, the DWE402W falls in DEWALT's mid-tier corded grinder lineup. The 1320-watt motor output places it above budget corded options like the WEN 944 (840 watts at $25.56) and provides meaningful headroom for sustained grinding. The 566 reviews and 4.7-star rating reflect consistent owner satisfaction across a solid sample size.
The 120V AC/DC compatibility means the DWE402W runs on standard household current and is suitable for job sites with generator power. The 15-inch length provides handling leverage on larger workpieces but adds to the overall bulk, which is a tradeoff worth considering for users who need to reach confined areas.
