A cordless impact wrench uses short hammering bursts to turn large nuts and bolts, which is why a 1/2 inch drive model is the common size for general shop work. Brushless motors are the usual choice now because they are electronically controlled and generally run cooler than brushed designs.
The six wrenches below range from a 275 ft-lb Craftsman to DEWALT’s 1900 ft-lb breakaway model. Torque, weight and kit contents come from each product’s listing page. We have not used these tools ourselves. All torque figures are the makers’ own, and the manual covers correct use, socket choice and torque settings.

A 1/2 inch 20V MAX wrench with a stated 1030 ft-lbs of fastening torque and 1400 ft-lbs of breakaway torque, four speed modes, a variable-speed trigger and an on-tool light. The highlight line says the kit includes a battery, charger and bag, while a bullet says the battery is sold separately, so confirm what arrives.
Suits: a ready-to-run kit. Strengths: four speed modes and a stated 1400 ft-lb breakaway. Weaknesses: conflicting kit wording. Skip it if you only want a bare tool.

3. Milwaukee M18 FUEL 2967-20 Impact Wrench
An 18 volt high-torque 1/2 inch wrench with a friction ring, a four-mode drive control and a brushless motor.

It measures 7.6 inches and weighs 2.7 kilograms.
Suits: M18 owners wanting compact length. Strengths: a short 7.6 inch body and four modes. Weaknesses: a muddled listing text. Skip it if you use another battery system.

- Assuming a bare tool ships with a battery.
Impact Wrench FAQ
Why does breakaway torque read higher?
Makers quote a higher figure for loosening than for tightening. Compare like with like.
Bare tool or kit?
If you already own batteries on that platform, a bare tool avoids a duplicate. Otherwise a kit covers everything.
The Short Version
For a four-mode kit, the DEWALT DCF900P1. For the highest stated torque, the DCF961B. For a short body, the Milwaukee. For a three-speed LXT tool, the Makita. For a lighter tool, the Craftsman. For a full kit from a lesser-known brand, the Seesii.
