We Test the 7 Best Cordless Impact Wrenches

We chose our winner based on subjective measures: how it handled, balance, and grip.

Over the past two decades we've tested hundreds of tools, but we never ran a competition this close. First, we tightened 38-inch and ¾-inch nuts with a torque wrench. Then we gathered seven cordless impact wrenches and removed the nuts. Somehow there wasn't a single tool with which we had a substantial complaint. We even tried it blindfolded, and could barely differentiate among our top performers. We chose our winner based on subjective measures: how it handled, balance, and grip. In terms of pure performance, though, the 41/2-star machines are just as good. Tools have come a long way in twenty years.

5 Stars


Volts: 20

Amp-hours: 5

¾-inch nut: 0.5 second

Likes: This enormous brute of a tool comes with three speed-limit settings of 400, 1,200, and 1,900 revolutions per minute, which provide control even when you can't see what you're doing. Despite its industrial-­duty motor, it's agile and easy to use, thanks to a slim handle and unfussy design.

Volts: 18

Amp-hours: 4

¾-inch nut: 0.5 second
