Overview
This is a 1/2 inch cordless impact wrench built to run on 20 volt Dewalt-compatible batteries, rather than shipping as a Dewalt branded tool. It carries a 4.4 star rating across 138 reviews, with about 100 units bought in the past month.
The title's wording, for Dewalt Battery, signals this is a bare tool made to fit the Dewalt 20V platform rather than a Dewalt product itself. That distinction matters at checkout, since no battery or charger is implied by the listing. Buyers already invested in Dewalt batteries get a lower cost way to add an impact wrench without buying another charger.
- 1/2 inch drive size
- Runs on 20 volt Dewalt-compatible batteries
- 4.4 star rating, 138 reviews
