Overview
DeWalt's DCF520B is a 20V impact wrench sold as a bare tool, meaning the box holds the wrench itself with no battery or charger included. It is built for driving lug nuts, bolts, and other large fasteners that need repeated rotational force.
DeWalt's 20V MAX line shares one battery platform across dozens of tools, so this impact wrench likely fits batteries and chargers you may already own if you use other DeWalt 20V gear. Because the listing only confirms voltage and the bare-tool naming pattern, exact torque and impacts-per-minute figures are not given here. Anyone buying it as their only 20V tool will need a battery and charger separately.
- 20V voltage rating
- DeWalt bare-tool B suffix, no battery included
Who it's for
Fits someone already invested in DeWalt's 20V MAX battery system who needs an impact wrench for automotive or heavy fastening work. Less useful for a first-time cordless tool buyer with no compatible battery on hand.
Pros and cons
- Runs on DeWalt's shared 20V MAX platform
- Suited to lug nuts and heavy fasteners
- Sold as bare tool, no battery or charger
- Torque output not stated in listing
Performance notes
An impact wrench like the DCF520B works by hammering out short bursts of torque instead of applying constant twisting force, which is what makes it effective on rusted or over-tightened lug nuts. Output should scale with the 20V battery's amp hours, though the listing itself does not publish a torque figure.
