Best DeWalt cordless impact wrenches

Top pick: DeWalt 20V MAX XR High Torque 1/2" (DCF900-class, hog ring anvil) — around 1,030 ft-lbs of fastening torque with a hog ring anvil, which is the combination that actually breaks loose rusted lug nuts, suspension bolts and chassis hardware. It's the sweet spot between a compact gun and a monster.

Who the others suit:

• DCF961 high-torque kit — if you want maximum breakaway force for trucks, trailers and heavy equipment, and prefer a kit with battery included.
• DCF891B mid-torque — a lighter, handier step down for engine bays and brake work where a full high-torque gun won't fit.
• Atomic DCF921 (compact) — for tight spaces and lighter automotive fasteners; not a heavy-duty breaker.
• DC820B / older 18V — only if you're already on that battery platform.

Match the anvil type and drive size to your sockets, and buy a kit if you don't already own 20V MAX batteries.
