Milwaukee M18 FUEL 2767-21: the professional benchmark
The Milwaukee 2767 is the impact wrench that convinced most professional mechanics to leave pneumatic tools on the shelf. Its 1,400 ft-lbs of peak torque exceeds most air guns, and the four control modes give you a precise tool instead of a sledgehammer. Mode 1 through 3 cover precision fastening (100-300 ft-lbs); Mode 4 is the full-power removal mode. The POWERSTATE brushless motor sustains high torque through an entire charge without fading, and the REDLINK electronics protect against overload and overheating.

DeWalt DCF899HP2: best for DeWalt platform users
The DeWalt DCF899 delivers 700 ft-lbs of max torque -- less than the Milwaukee but sufficient for all passenger car work and most light truck applications. Its three-speed control prevents over-tightening on delicate fasteners. The included FLEXVOLT adapter lets you run it from either 20V MAX or 60V FLEXVOLT batteries, giving excellent runtime flexibility. For users already invested in DeWalt's ecosystem, it is a natural and well-performing choice.
Buying considerations
Torque rating
Distinguish max (breakaway) torque from fastening torque. For lug nuts and automotive work, 600+ ft-lbs of breakaway torque handles 95% of situations. For seized bolts and heavy truck work, look for 1,000+ ft-lbs.
Drive size
1/2 inch is the automotive standard. 3/8 inch is for lighter precision work. 3/4 inch and 1-inch drive are for heavy construction and industrial.
Multi-speed control
Variable or multi-mode torque control prevents damaging softer fasteners or plastic threads when precise torque is required.
Head length
Shorter heads (under 8 inches) fit in wheel wells and tight engine bays. Check this spec if you work in confined spaces.
Battery platform
A shared battery platform across your tool collection saves cost and weight. Factor in battery purchase if switching platforms.
Questions answered
Most passenger car lug nuts torque between 80-120 ft-lbs. An impact wrench producing 300+ ft-lbs will remove them easily. Truck lug nuts and seized fasteners may need 600+ ft-lbs.
For most automotive and construction applications, modern 18V-20V cordless impact wrenches match or exceed pneumatic performance. Pneumatics still have an advantage in industrial settings with continuous heavy use.
Max torque is the peak output in short burst mode for breaking fasteners loose. Fastening torque is the controlled output for driving fasteners to spec without over-tightening.
1/2 inch drive is the standard for automotive work (lug nuts, suspension bolts). 3/8 inch drive is better for lighter assembly work and fits in tighter spaces.
