A cordless 1/2 inch impact wrench makes quick work of lug nuts, suspension bolts, and stubborn fasteners in the garage. This comparison puts one bare tool each from DEWALT, Makita, and Bosch side by side on price, listed torque, and warranty.
How We Chose
We picked one 1/2 inch brushless impact wrench from each of three established brands, all available on Amazon. These tools are not the same class: the DEWALT and Makita list high torque numbers, while the Bosch is sold as a mid-torque wrench with a much lower torque figure. All three are bare tools, so a battery and charger are extra, and batteries do not swap between brands. The torque numbers come from the DEWALT and Makita product pages and, because we could not find a Bosch product page for this model, from the Bosch listing, and they are manufacturer claims that may be measured differently. We did not find a Makita warranty in the Amazon listing fields we checked, but Makita’s product page lists 3 years. Warranty terms come from the manufacturer’s own website where it names the model or product line, then from the Amazon listing, and we say so where neither gave a length. This is a researched comparison, not a hands-on test, so we make no claims about real-world speed or how long they last beyond what each listing says. Prices are Amazon prices checked in September 2026 and can change.

Check Price on Amazon →Our Take
If you want the most torque on paper, the DEWALT lists the highest numbers and a 3 year warranty at a middle price. If you want the lowest price and a lighter-duty wrench with a 5 year warranty, the Bosch mid-torque model is the value pick, though it lists far less torque. The Makita costs the most and lists more torque than the Bosch but less than the DEWALT. Check which battery platform you already own, because that often decides the choice. We did not test any of them.
Frequently Asked Questions
Do these impact wrenches come with a battery?
No. The DEWALT listing says the battery is sold separately, the Makita listing says tool only, and the Bosch listing says bare tool. You need a compatible battery and charger for each.
What is the difference between fastening torque and breakaway torque?
Fastening torque is the most force the tool lists for tightening a fastener. Breakaway torque is the most it lists for loosening a stuck one, which is why it is usually the larger number. Both are manufacturer claims.
Which of these has the longest warranty?
The Bosch listing says a five year limited warranty on its 18V cordless power tools and the DEWALT product page says three years. We did not find a Makita warranty in the Amazon listing fields we checked, but Makita’s product page lists 3 years.
Can I use a DEWALT battery on a Makita or Bosch tool?
Cordless tool batteries generally only fit tools from the same brand and platform, so plan on buying into one battery system. Check the battery compatibility on the listing before you buy.
