  1. Torque 

Before purchasing an impact wrench, check the torque-producing capability.

What Is Torque?

Do you know what torque is? Torque is the turning effect produced by an object.

If the torque is higher, the influence on the bolt you are working on will be high too. It will make you handy to tighten the screws and bolts.

Strongest Impact Wrench with High Torque

The Milwaukee 1-inch impact claims to be the strongest impact wrench with a torque-producing capacity of 1800 ft-lbs.

Low Torque

If the wrench produces less turning effect, don’t opt for it. 

Minimum Value for Torque

A value less than 200 ft-lbs is not enough for a wrench to get the job done. Carefully check the rating and select the one with better torque. A High torque air impact wrench will easily tighten and loosen the bolts, screws, and nuts.

  1. Rotations per Minute (RPM)

Like the torque, an impact wrench with high RPM is considered the best. 

Standard RPM value 

An impact wrench with a 3,000 or above RPM is considered ideal.

Lower RPM

Another factor for impact wrench is high Impacts per Minute or high Blows per Minute. IPM provides the quick loosen of a bolt associated with enough torque.

For now, the best impact wrench will be the one with high torque, RPM, and IPM. Check the ratings with the specification, and yup!
