Air impact wrench how it works

An air impact wrench, also known as an air pistol or pneumatic wrench, is a strong instrument used to tighten and loosen nuts and bolts. It is a sort of impact wrench that is powered by compressed air.

How does a pneumatic impact wrench operate?

Using a motor to move a series of gears that generate torque, an air impact wrench generates torque. When pressurized air is fed into the wrench, it is channeled to a series of vanes that rotate the motor. The rotational force is then transferred to the output shaft by the motor rotating the gears inside the wrench. Attached to the output shaft is a socket or bit used to tighten or loosen nuts and bolts.

Air impact wrenches are designed to generate high levels of torque fast and effectively. This makes it a popular tool for car maintenance and repair, as well as construction and industrial applications.

Considerations When Purchasing an Air Impact Wrench for Less Than $100

When purchasing an air impact wrench for less than $100, there are a number of factors to consider to get the best value. The below features will help you in picking the best impact wrench air for your project:


The truth is, you can’t accomplish all your bolts, screws, or nuts fastening or unfastening tasks with a single impact wrench. Why? Because torque requirements vary from task to task. It would be best if the impact wrench comes with the right torque as per the project requirement.

Additionally, depending on the frequency of using the tool also matters since all models are not manufactured to be used frequently. At the same time, some others are so powerful that you can use them regularly.

Moreover, few designs of air impact wrenches are efficient enough in dealing with multi-purpose use and can handle many projects.

Torque output

When selecting an air impact wrench, the torque output is among the most important aspects to consider. It defines the wrench’s strength and capacity to undertake difficult tasks. Seek a wrench with at least 250 foot-pounds of torque.

Generally, higher torque means the air impact wrench is powerful, and you can handle a project more flexibly. However, you may not require a powerful impact wrench since a low-powerful wrench can handle small to medium-sized tasks such as loosening little jolts. So, always check the torque before you buy an air impact wrench for your project.


From the name itself, you can get an idea that air impact wrenches require an air compressor to run. While picking one, make sure it has proper airflow. So, when choosing an air compressor, you must make sure it is suitable for your selected one.

Next, you have to monitor the base hose size and arrange it with the proposed adaptor’s embellishments. With this feature, no air will lose within the air impact wrench and the compressor.


The air impact wrench’s speed influences how quickly it can perform a task. Seek a wrench with a minimum speed of 7,000 RPM.

Drive size

Drive size refers to the square drive connecting the wrench to the socket. 1/2-inch and 3/8-inch are the most frequent drive sizes. Select the size that corresponds to the sockets you already own.

Construction material

The toughness and lifetime of an air impact wrench are determined by its building material. Consider purchasing a wrench made of premium materials such as steel or aluminum.


As stated earlier, an air impact wrench is a handheld tool, which means weight plays one of the crucial roles when buying an excellent air impact wrench.

Characteristically, air impact wrenches are lightweight so that the user can work with them for a more extended period and move comfortably from one place to another.

Pick a model that has a weight range of 4 – 6 lbs. This way, you will not face hand fatigue while working with it on a larger project.


Air impact wrenches are designed to work in tight spaces. That is why it requires a little profile. However, your prerequisite and initiative adjust the size according to your requirement.

A compact-sized air impact wrench is best for tight spaces, but these types have one drawback – they are less powerful, and torque is less. So, look for an impact wrench that is well-balanced between power and size.

Ergonomic Design

Will you feel comfortable working with an air impact wrench that won’t fit in your palm? Undoubtedly, your answer will be a BIG NO.

So, go for an impact wrench that fits in your palm comfortably. The air impact wrench has to be ergonomic and made of durable material to carry the weakness of the hand and deliver the best result.


A warranty is required when purchasing any tool. Consider purchasing a wrench with a comprehensive guarantee covering any flaws or malfunctions.

How to Use the Air Impact Wrench?

Using an impact wrench is not a challenging task. Follow the below steps to work with it.

  • Before starting, grease your air impact wrench.
  • Next, create a connection between the air compressor hose and the impact wrench. Make sure the connection is made correctly.
  • Inspect the socket to make sure that no problem is there to start working.
  • Place your air impact wrench on the tip of the targeted bolts or nuts.

Questions & Answers about Low-Cost Air Impact Wrenches

What size air impact wrench do I need?

Air impact wrenches are available with ½”, ¼,” 3/8″, ¾” and 1″. Before determining the air impact wrench size, learn your project requirement. However, 3/8″ and ½” air impact wrenches offer enough power to remove a tough lug nut.

How does an electric impact wrench differ from an air impact wrench?

One type of impact wrench uses compressed air as its power source, while another type uses electricity. But, you’ll need an air compressor to use an air impact wrench, which reduces its portability. The force of electric impact wrenches may be diminished by their greater convenience.

If I want to use an air impact wrench, how big of an air compressor do I need?

Most air impact wrenches require a compressor with a cubic foot per minute (CFM) value of 4.0 or above to function.

Can you tell me how to care for my air impact wrench?

Keep your air impact wrench in good working order by regularly cleaning and oiling it. You should oil the air intake and wipe it off with a clean cloth after each use. Maintaining a well-functioning wrench also necessitates routinely inspecting and changing the air filter.

Can I use a 3/8-inch socket with a 1/2-inch air impact wrench?

With the right socket adaptor, a 1/2-inch air impact wrench can be used with 3/8-inch fastener holes. Keep in mind that adapters may reduce the wrench’s efficiency and torque.

Final Words

The best pneumatic impact wrench for the money is the best option to loosen or fix nuts and bolts tasks faster. You can comfortably fix the brake, exhaust fan, or tire rotation of your vehicle with it.
