Overview
The DEWALT DCG412P2 is a cordless angle grinder running on DEWALT's 20 volt battery platform at up to 8,000 RPM, built for cutting and grinding metal without a cord or air line.
DEWALT sells this within its 20V cordless grinder lineup, aimed at users who want angle grinder power without staying tethered to an outlet. The listing does not specify disc size, kit contents or battery count, so buyers should confirm those details fit their needs before ordering.
- Cordless 20V battery powered angle grinder
- Up to 8,000 RPM
- 4.8 star rating from 382 ratings
- About 200 bought in the past month
Who it's for
Fits tradespeople and DIYers who need a cordless angle grinder for metal cutting, grinding or surface prep on the DEWALT 20V platform. Less useful for continuous heavy grinding sessions where a corded grinder's unlimited runtime matters more.
Strengths and trade-offs
Drawn from this product's published specifications.
- Cordless operation on the 20V DEWALT battery platform
- Rated 4.8 stars across 382 ratings
- About 200 bought in the past month, one of the more popular grinders in this batch
- 8,000 RPM is lower than many corded angle grinders
- Runtime depends on battery capacity, not specified here
- Disc size and kit contents aren't listed
Performance notes
Running off 20V batteries rather than a cord, this grinder trades some sustained runtime for the ability to work away from an outlet. Its 8,000 RPM speed is on the lower end for angle grinders, which generally favors control over aggressive material removal.
