The 10 Best Cordless Impact Wrenches

Battery-powered impact wrenches ranked from live Amazon data — for lug nuts, suspension bolts, and rusted hardware.

These are the best-selling cordless impact wrenches on Amazon right now, scored on rating, review volume, and a few features that matter on this tool: a complete kit, a hog ring anvil for quick socket changes, and selectable speed modes. The list splits into two camps: DEWALT, Milwaukee, and CRAFTSMAN tools with up to 1,400 ft-lbs of breakaway torque, and $50-80 kits that include batteries but lock you into their own battery. Torque figures on the budget listings are the maker's own claims, not independent tests.

How we rank

Every tool gets one score from 0 to 100, weighted 50% on its star rating, 30% on how many people have reviewed it (more reviews = more confidence the rating is real), and 20% on the features that matter for the job. The list is ordered by that score. Best Overall is our pick for the best all-around, ready-to-use tool; Best Budget the best value at or under $80; and Money No Object the one to buy if price is no object.

Buyer's guide

How much torque do I need to take off car lug nuts?

Most passenger-car lug nuts are torqued to roughly 80-100 ft-lbs, so a 300-400 ft-lb wrench breaks them loose easily. Rusted nuts, trucks, and hardware someone overtightened with an air gun are where 1,000+ ft-lbs of breakaway torque earns its price.

What's the difference between fastening torque and breakaway torque?

Fastening torque is how hard the wrench tightens. Breakaway (or nut-busting) torque is how hard it can hit to loosen something stuck, and it is always the bigger number. When a budget listing shows one figure, check which one it is before comparing it to a DEWALT or Milwaukee spec.

Impact wrench or impact driver?

An impact wrench has a square drive (usually 1/2 inch) for sockets and is built for nuts and bolts. An impact driver has a 1/4-inch hex chuck for screw bits and is built for screws and lag bolts. If your job is wheels and car parts, get the wrench.

Kit or bare tool?

If you already own DEWALT 20V or Milwaukee M18 batteries, the bare tool saves $100 or more. If you don't, a kit is cheaper than buying the tool, a battery, and a charger separately. The budget brands only run on their own batteries, so buying one means starting a new battery platform.

What is a hog ring or friction ring anvil?

It is a spring ring around the square drive that holds a socket on by friction. Sockets snap on and off by hand, with no pin to line up. The alternative, a detent pin, holds sockets more securely but is slower to change.

1/2-inch or 3/8-inch drive?

1/2 inch is the standard for lug nuts and suspension work, and most of this list uses it. 3/8-inch tools are smaller and fit into engine bays and tight spaces, but they have less torque and need an adapter for 1/2-inch sockets.

Tools to avoid

CloudDream

CloudDream 1/2" Cordless Impact Wrench Compatible with DeWalt Battery, 369 ft-lbs, 2-Speed, No Battery

3.7 49 reviews $19.99

A $20 unbranded wrench whose listing can't agree with itself on how many speeds it has or even what tool it is, sold to run on batteries from a brand that doesn't make or warranty it.

Why we'd skip it

The title says 2-speed; the bullet points say 3 speed modes
The listing's own details give the model as "Ratchet-7" and the included component as a "Cordless Ratchet Wrench", not an impact wrench
Marketed for DeWalt 20V MAX batteries, but it isn't a DeWalt tool: no DeWalt warranty, and its spec table lists it as 21V
3.7 stars, the lowest rating of any impact wrench in the search results we reviewed
