Ingersoll Rand 2850MAX-6    1" Drive Impact Wrench

The Ingersoll Rand 2850 series are among the most powerful 1" drive pneumatic impact wrenches produced by Ingersoll Rand. These impact guns are designed for heavy-duty commercial use. The most popular model is the IR 2850MAX-6 which features a 6-inch extended anvil making lug nut removal inside deep truck and semi-trailer rims a breeze.

With 2100 foot-pounds of nut-busting torque, using a solid steel impact mechanism, this gun handles the most demanding jobs with ease. Free speed is 5550 RPM for quick spinning of fasteners. The sound level is 96.7 dB, which is loud, but average for 1 inch drive pneumatic wrenches in this power range. The hammer hits hard with 770 BPM.

Ingersoll Rand's 2850 series impact guns have been made 25% lighter than the competitor's one inch air impact wrenches, making them much easier to use. A 360-degree swiveling side handle can be rotated completely around the tool to any convenient position. The 1/2" NPT air fitting also can rotate 360 degrees to help keep the heavy air hose required to power this beast.

  • POWER: 2100 ft/lbs. of extreme continuous torque for tough jobs.
  • ERGONOMICS: 25% lighter than the industry leading 1inch impact wrench.
  • DURABILITY: Steel core and impact resistant housing stands up to rough use.
  • CONTROL: Side handle rotates 360 degrees for ease of use.
  • REACH:  Features a 6" extended anvil for increased reach.

The Ingersoll Rand 2850MAX is designed for heavy duty applications such as industrial maintenance, heavy truck and tire changing and heavy equipment repair. If you need maximum power, this gun delivers. This 1" impact wrench is backed by an Ingersoll Rand 2-year warranty.

This is a powerful 1-inch pneumatic wrench requiring a substantial amount of air flow for optimal performance. Air consumption at load for the 2850MAX is 56 SCFM at 90 PSI operating pressure. Average air consumption is 14 CFM. For continuous duty usage you'll need a large air compressor. In any case it is recommended to use air lines of 3/4 diameter and direct connections to the gun without the use of quick-connect fittings for maximum air flow.

Ingersoll Rand pneumatic tools are assembled in the USA and for the quality and power of the gun, the price is competitive. The 2850MAX-6 1" Air Impact Wrench was priced around $560 at the time of this review update in December 2021.

Around 85% of Amazon reviewers award 4 to 5 stars, the 2850MAX is a solid buy if you need a commercial-quality 1" air impact wrench.

Quick Tips:  

1. Use short, large diameter air hoses  and high-flow air couplings for maximum power.

2. Put both hands on the impact wrench for better results removing stubborn nuts.

3. Just snug wheel lug nuts with impact , then use torque wrench to tighten to specifications.

The Bottom Line

The Ingersoll Rand 2850MAX 1 Inch Drive Air Impact Wrench is a top choice among professional heavy equipment mechanics. This gun offers tremendous maximum torque of 2100 foot pounds, from an easy to handle tool. 

The 2850 is not intended for casual home use, unless of course, you have a commercial size compressor that can supply this beast with 56 CFM of air. However, for a commercial shop or repair facility this is the gun you need to effortlessly remove those stubborn fasteners that the 1/2" and 3/4" guns won't budge.
