Product Details

The MAXIMUM 1/2-in Air Impact Wrench is designed to quickly and efficiently remove stubborn lug nuts. Boosted by twin hammer power, this air wrench delivers 2x the working torque when compared to a standard air-powered impact wrench. Powerful and robust, this pneumatic drill delivers up to 650 ft-lb of torque (7500 RPM) and can tighten or remove stubborn nuts and bolts up to 5/8”. A forward/reverse switch allows you to go from tightening a nut or bolt to removing it easily. A built-in regulator lends precise speed and torque control to this air impact wrench, while the composite body provides greater durability and reduces vibrations. The ergonomic rubber grip helps to reduce hand fatigue during extended use of the air tool, while handle exhaust allows you to direct exhaust air away from the work area. A screened inlet prevents dirt particles from entering the air intake, preserving the tool’s longevity. This product includes an air-powered impact wrench, a 1/4” NPT plug, and a bottle of oil.

replace the 16x2.5 o-rings when the inlet leaks

a year ago
The air inlet will leak after a few years. Many people have reported this problem. Just remove the roll pin and replace the two 16x2.5 orings (OD 21, ID 16). Back to new. See the assembly diagram in the manual.

Q: Compressor & Air requirements What is the compressor gallon capacity requirements for this tool. Is a 3 Gal compressor enough?

10 years ago
3 Answers
  • A: Adding to my last answer. I have just purchased this tool. Here are the specs off the box. >3.7 CFM & 3.0 HP. A 2 HP compressor with a 5-6 gal tank will be adequate for light duty intermittent use. It increases from there with HP and tank capacity. Hope this helps. Cheers >3.7 CFM means your compressor needs to be capable of greater than this number.
