Buyer’s Guide For Best Air Impact Wrench

Best Air Impact Wrench

 Why should you use an air impact wrench?

Air impact wrenches come handy when you want to repair your car’s tire and when you encounter a jammed bolt. Though it is a small tool, it puts a large amount of power right into the hand allowing the mechanic to undo or redo the bolts in real fast time. An air impact wrench makes use of compressed air to spin a motor that transfers energy to a rotating mass.

This mass carries a large amount of momentum allowing it to act as a hammer. The momentum is later transferred to an anvil to deliver the force directly on the problem nut. It then becomes too easy to release within the least span of time. There are a number of advantages of using an air impact wrench and those are,

  • It helps a great deal in tightening and loosening the bolt.
  • While tightening you can control the torque and the extent to which the nut is tightened.
  • It avoids exerting over force on the underlying structure and stripping the threads.
  • It can be used efficiently to loose even stuck and rusted bolts easily.

How should you choose your air impact wrench?

Before buying an air impact wrench, it is important to ascertain a few important aspects like drive size, power, durability, etc. Some may prefer an ergonomic design to make the best use of the wrench and some might choose lightweight models. Let us discuss the most important things that you should keep in mind before choosing an air impact wrench.

  • Size of the drive
  • Speed and Torque
  • Weight of the air impact wrench
  • Noise Level
  • Build construction
  • Budget and warranty

Size of The Drive:

The size drive is the most important feature to keep in mind before choosing a wrench. The normal size of the wrench ranges between ¼ to 1 inch. Drives that are smaller than ½ inch are meant for lighter work and they have less torque. Wrenches that are more than ½ inch are for heavier work like industrial construction and heavy vehicle repair.

Wrenches that are ½” size are most popular and are commonly used. They offer a good balance between power, size, cost, and versatility. They are good enough to handle all sorts of car repairs and for removing nuts from almost anything, irrespective of the condition of the nut.

Speed and Torque:

Torque is the amount of twisting force that the wrench exerts into the nut or bolt. This along with speed determines the quantum of force you need to exert in order to tighten or loosen the nut at the least possible time. Greater the torque, better is the wrench as it gets capable of handling bolts of even larger sizes.

Air impact wrenches with adjusting torque settings allow you to control the force you exert while tightening the bolt. It also allows you to measure the amount of compressed air to be used while doing work that does not mandate full torque.

The speed of the air impact wrenches determines how fast and efficient you can screw or unscrew the bolts and how well your impact wrench works for loosening the stuck bolts. A wrench with higher speed works better to loosed stuck bolts as the hammer can strike the anvil pretty frequently. One important tip to note here is that wrenches with higher speed feature a lower torque.

Weight of The Air Impact Wrench:

This is the most important factor to consider before spending your money on the wrench. A heavier wrench is more tiring to hold, if you happen to work on it for a longer period of time. Apart from being tiring, it is difficult to work with and can result in accidents if the arm is fatigued.

Choose a wrench that has a long barrel and a compact structure so that it is easy to each and is capable of attending to bolts of all sizes. Though all of the wenches we reviewed use a pistol style construction, there are inline wrenches that can reach bolts where the air impact wrenches cannot reach.

Noise Level:

We have to admit that these tools create a lot of noise and it is important to have adequate ear protection while using them. Different wrenches create the different amounts of noise. But wrenches from Aircat and Nitrocat at the good in operating at reduced noise levels. Wrenches from this brand are quiet when compared with wrenches from other manufacturers.

Build Construction:

Build quality is an important consideration to make while choosing an air impact wrench. This is because these tools are expensive and are of use frequently. Most of the air impact wrenches make use of reinforcing housings that are of either metal or kevlar over the body. The best way you can choose a wrench of excellent build quality is by checking the customer reviews.

Budget and Warranty:

We have to admit that an air impact wrench can be a huge purchase. Check the warranty from the manufacturer before making the investment. Most of the manufacturers offer warranties from one to three years, choose a product that has a longer warranty period. Wrenches with a higher price have more features and better construction. But it doesn’t mean you have to spend a fortune on them. You can also choose budget wrenches for intermittent use.


Best Air Impact Wrenches FAQs:

What type of air compressors will I need?

For a single air impact wrench, it is important that your air compressor should offer a minimum of 6. CFM at 90 PSI for an average ½ inch impact wrench.

What is CFM and PSI?

PSI means pounds per square inch; it measures the amount of air that gets compressed in a given space. It is the measure of stored air. CFM means cubic feet per minute. This is the amount of air flowing at a given moment. It measures the power an air impact wrench will have at its disposal.

What are the places I can use air impact wrenches?

They are designed to deliver high torque output at a limited time. They are good for jobs that involve removing and reinstalling lug nuts, that you can find while changing tires on a car. You can also use it to remove stuck bolts that were untouched for years.

Main Features To Look For in Your Air Impact Wrench:

Best Air Impact Wrench

  • Torque
  • Load speed
  • Impacts per minute
  • Single hammer or twin hammer
  • Portability


This is the measure of the force the wrench is capable of applying on a bolt while turning it. It is directly proportional to the drive size of the wrench. Torque is limited by the airflow that the compressor can provide.

Load Speed:

This is the measure of how fast the impact wrench can turn when there is nil resistance from the bolt. It also states how fast one can screw and unscrew bolts when you are not breaking them loose.

Impacts Per Minute:

Impact wrenches can get bolts to lose faster as they make use of the mechanism that hits the bolt rapidly rather than applying constant torque on it. This jolts the bolt and knocks it loose. Look at the specification for the impacts per minute, this will give an idea about how quick your instrument is.

Single Hammer or Twin Hammer:

The hammer hits the anvil of the wrench and loosens the bolt. Some of the best impact wrenches at modern days have a twin hammer design that is capable of hitting the anvil at two places, with increasing force in each impact.


This is the second most important feature to look for in an air impact wrench and the first being the ability of the instrument to break the bolts loose. Choose a device that is able to it in tight places easily, so that you can carry them with you to handle all circumstances.


Final Words:

Air Impact Wrenches are excellent pneumatic tools that pack sufficient torque to enable you to deal with the stubborn nuts and toughest bolts. With the help of their ergonomic handles that are able to absorb high impact torque and serve as your elegant tightening or loosening fasteners. We hope our guide will help you in choosing the best wrench for your pneumatic needs.
