## What reviewers say

One whitelisted tester, Pro Tool Reviews, bench-tested this grinder hands-on and scored it 8.9/10. They praise the real power boost on an 8.0Ah battery and the comfortable slim grip, but flag that DeWalt's own FlexVolt kit costs only about $20 more for much more power. No other whitelisted outlet reviewed it. (Based on 1 review, 1 lab-tested, 2021-04-02.)

Praised: Noticeable power boost when running an 8.0Ah battery; Slim barrel grip with generous overmold is comfortable and effective; E-clutch stops a bound-up wheel in under 1/10th of a second.
Flagged: FlexVolt kit costs only ~$20 more for much higher power; No bare-tool option at review time; sold only as an 8.0Ah kit; Sits only in the second of four tiers in DeWalt's grinder lineup.
Disagreement: Only one whitelisted tester (Pro Tool Reviews) covered this model, so cross-source agreement cannot be assessed; their single verdict is positive with a value caveat versus the FlexVolt grinder.
