In-Depth Review
The AIRCAT 1150 punches way above its weight class. At just 86 dBA, it's one of the quietest pneumatic impact wrenches we've tested — your ears will thank you after a full shift. The patented tuned exhaust pushes air away from the operator while the ergonomic composite grip reduces fatigue during extended use.
We ran this wrench all day on lug nuts, rusted bolts, and structural connections. It loosened everything we threw at it without hesitation. The twin-hammer mechanism delivers smooth, consistent impacts without the jarring kickback of cheaper wrenches.
Best for: Mechanics, heavy equipment technicians, and construction workers who need raw power without ear-splitting noise levels.

In-Depth Review
Milwaukee changed the game with the 2864-20. At 1,400 ft-lbs loosening torque, it matches — and often exceeds — pneumatic wrenches while cutting the cord entirely. ONE-KEY Bluetooth lets you customize torque settings, track tool usage, and lockout the tool if it's stolen.
The 4-mode DRIVE CONTROL gives you full control: self-tapping screw mode, fastening mode, and two impact modes. The brushless motor runs cooler and lasts longer than brushed alternatives. If you're invested in the M18 platform, this is a no-brainer.
Best for: Cordless-only jobsites, structural steel work, and contractors who want smart tool management.

Buying Guide
What to look for before you buy
Torque Output
More torque means more nut-busting power. For automotive work, 700+ ft-lbs is sufficient. For heavy equipment and construction, look for 1,000+ ft-lbs loosening torque.
Pneumatic vs. Cordless
Pneumatic wrenches require an air compressor but deliver consistent, unlimited power. Cordless wrenches offer freedom of movement but have limited battery life. Consider your work environment.
Our Verdict
The AIRCAT 1150 Killer Torque is the best affordable impact wrench. The Ingersoll Rand 2235TiMAX is the best cordless.
