About Ace of Speed
Ace of Speed is an independent guide to cordless impact wrenches. We help you pick a wrench that breaks loose the nuts and bolts on your car, truck, trailer or mower.
Our readers are home mechanics and DIYers. Many of them are tired of fighting stuck lug nuts with a tire iron and want a tool that does the hard part for them.
What we cover
We cover battery impact wrenches from brands like DeWalt, Milwaukee, Makita, Craftsman, Bosch and Flex. We also explain the numbers on the box, like fastening torque, breakaway torque, drive size and anvil type.
You'll find short lists by torque and size, help with tire and yard jobs, model matchups, single-model reviews and plain torque know-how.
How we pick products
We read the specs, features and maker details for every wrench we cover. Then we look at what owners report after using one on real jobs.
We turn that into clear picks and comparisons in everyday words. Our How we research page explains the steps.
What we are not
We don't make or sell impact wrenches, and no brand pays us to rank its products.
Ace of Speed isn't affiliated with DeWalt, Milwaukee, Makita, Craftsman, Bosch, Flex or any other tool maker.
We don't claim to have tested every product ourselves. When we pick something, we tell you why, based on its specs, its features and buyer feedback.
How we earn money
Some links on this site go to stores like Amazon. If you buy through them, we may earn a small commission at no extra cost to you.
That never changes which products we pick. Our affiliate disclosure has the details.
