Best cordless 1/2 inch impact wrenches

Top pick: Milwaukee M18 FUEL High-Torque 1/2" impact wrench. For automotive work nothing here comes close on grunt — 1,400 ft-lbs of nut-busting torque, brushless, and it's the tool most pro techs reach for on lug nuts and rusted suspension bolts. Note it's tool-only, so you'll need an M18 battery and charger.

Who the others suit:

• Milwaukee 2767-20 — same high-torque family if you want the older, proven version.
• Makita XWT08Z — 1,180 ft-lbs nut-busting; a strong alternative if you're already on Makita LXT batteries.
• DeWalt DCF921P2 kit — compact and battery-included; great for engine-bay and mid-torque jobs, not the heaviest bolts.
• Ridgid 18V 4-mode kit — 1,300 ft-lbs breakaway with a battery in the box; best value for a home garage.
• Kobalt 24V — light-duty and budget-friendly for occasional wheel swaps.
• Ryobi 18V / Alloyman / UNTIMATY — homeowner-level torque; fine for lug nuts on a car, not for seized suspension hardware.

Skip the 3/8" Ryobi kit and the low-torque Makita XWT15Z if you need real 1/2" drive power.
