Buying Guide For Pneumatic Impact Wrench

If you want the best air impact wrenches for home use, then you must make sure that your tool checks out these points mentioned below.

Torque

This is the most important feature of any wrench. These air drivers are used because of their ability to retain the rotational force within its components. Now that is exactly what we call the torque.

If the torque is lower than required, then the nuts will not budge from their place. On the other hand, if the torque is higher than what is required, then the nuts and bolts will be damaged by the tremendous force of the hammer.

It is, therefore, very vital that you look at the torque capacity of the impact wrench for your car before buying it.

Weight

Since this is a handheld device, you have to pay extra attention to the weight of its body. Lightweight tools are good, but not in every situation. If you are doing heavy-duty work, then a lightweight tool will not be able to deliver the amount of force required.

Therefore, you have to find a sweet spot between the weight and the force requirement. Buy a tool that is not the lightest, but one that is comfortable to hold, and sturdy enough to pull through heavy-duty tasks quickly enough.

IPM

As you might have read this in our best air impact wrench reviews, you must have wondered about its meaning. This suggests the impacts on the number of impacts that will happen every minute. The higher this number, the more impacts will happen between the hammer and the anvil. Thus, your work will be done faster.

Zero Load Speed

This will tell you the speed at which the hammer will turn when there is no load on it. More speed means that your nuts will get tightened or loosened faster. But sometimes, tools with higher speed are not ideal because they have low torque power.

That means your work will get done faster, but it will take up more air. So you will have to stop to refill the tank or get a bigger tank in order to finish many tasks at one go.

How Does An Air Impact Wrench Work?

First of all, it needs power. So there is a power supply installed within the tool. In the case of the air driver, this power comes from a tank of air that is incorporated within the tool.

The power feeds a motor inside. Then the motor takes it to the rotating mass. In other words, it takes power to the hammer. The hammer rotates and holds on to this rotational force, which it then transfers to the anvil.

Now, the job of the anvil is to make turns in the socket where the nuts or bolts are fastened. The direction of these repetitive turns is what causes the fasteners to settle in tight, or come out loose.

What Size Air Compressor Do I Need for Impact Wrench?

Two things determine the quality of an air compressor – the amount of pressure it can create in the air, and the flow at which the air is passed out.

The size of the air compressor you need depends on the size of your wrench.

While buying the compressor, you should also look at the size of its tank. The larger the tank in your air compressor, the more air it can hold. More air means that you won’t have to wait long between consequent impacts.

As a general rule, remember that the bigger the tool, the bigger should be the air compressor.

The most commonly used wrench is the ½-inch impact wrench, and with these, you need a compressor that will be able to provide 4-5 CFM at 90 PSI. (Note: CFM is a measure of airflow, and PSI is a measure of air pressure.)

Tank size should generally be about 20 gallons so that you can work uninterrupted.

For earthquake xt impact wrench of ¼-inches and 3/8-inches, you will need a compressor of 2-3 CFM at 90 PSI. With a ¾-inch one, you will need 7 CFM at 90 PSI.

All of these with run pretty smoothly with a tank capacity of about 20-30 gallons.
