Our take
If you already own DeWalt batteries, this is the easiest upgrade you can make. It removed lug nuts from an F-250 in a fraction of a second in Popular Mechanics testing — that's all you need to know.
This is the impact wrench pros actually use on job sites. If you're doing automotive work, structural bolting, or anything with large fasteners, the 2767-20 is the only cordless tool that competes with air-powered wrenches.
