Electrical and Air Impact Wrenches
If you require quiet impact wrenches, then the electrical ones are best for that situation. The air impact wrenches are large and produce noise.

Remember, the electrical impact wrench is not suitable for heavy-duty work. For heavy work, the air impact wrench suits best. It opts for a compressor to handle the high energy generation.
Tip
Use ear muffs if you opt for an air impact wrench.
- 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.
High Torque
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.

- 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
Don’t opt for a wrench having low RPM because it will take long enough to get the job done.
Tip
It must be the top priority for the buyers to select the impact wrench with a high rotation per min (rpm) rating. You may find the rating in the product description.
- Impacts per Minute
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.
High IPM
When the IPM rating is also high, it’s the best wrench to purchase. The contact between the impact wrench and the target will be high.
High IMP provides faster working of a 1-inch impact wrench than a low IMP wrench.
Tip
For now, the best impact wrench will be the one with high torque, RPM, and IPM. Check the ratings with the specification, and yup!
You got the best one.
