Impact wrenches are designed to ease your job. Be it loosening bolts, tightening nuts, or vice versa, a good impact wrench can do that in seconds where you need to apply a lot of pressure when doing it manually. And generally, a 1/2-inch air impact wrench is great for all-around usage. You can change the tires of your car, fix various appliances or work on a DIY project easily with a good quality air impact wrench.
Before beginning with reviews we would like to draw your attention to the difference between an electric and a pneumatic air impact wrench. Although both the wrenches look and work similarly, there is a difference in the torque they draw out.
An electric impact wrench is good for small jobs where you do not need much torque. For example, you can use a corded or battery-powered impact wrench for assembling furniture. These low-torque impact wrenches are good for occasional use. Then are pneumatic air impact wrenches that deliver enough torque to fix/loosen lug nuts. Such tools are good for intensive usage. They are ideal for both home and professional use.
With so many options available in the market, it can be quite difficult to pick the right one. Also, you cannot just buy and experiment with a new tool every month as these tools are quite expensive.

What psi do you need for an impact wrench?

How to choose the best 1/2″ Air-Powered Impact Wrench?
Drive Size (1/2″ in this case):
There are different drive sizes for different jobs. Here, we’ve only listed down the best impact wrenches with a 1/2-inch drive that covers almost 90% of the requirements. A 1/2″ impact wrench is an ideal choice for homes and garages as it can handle most of the nuts, bolts, and fasteners. Also, it is best for changing tires of vehicles that include SUVs, food trailers, RV’s, etc.
The torque of a wrench determines its power. So might have seen that different models offer different loosening and reverse torque. The main purpose of an impact wrench is to loosen lugs/bolts/nuts which is why more attention is given to forward torque or loosening power. However, many models also offer reverse torque for tightening screws/bolts/nuts that fits in that particular drive.
Free Speed (RPM)
RPM stands for rotations per minute and this determines the workforce of the tool. It is obvious to have higher torque with high RPM. While light-duty tools offer low rpm speed, a heavy-duty air impact wrench offers free speed in the range of 7500-9000 rpm that is enough to cause a high torque and remove rusty nuts/lugs easily.
Easy To Handle
If working for long hours, buy a lightweight impact wrench that causes less fatigue on your arm and wrist. And luckily, many good 1/2″ air wrenches have a lightweight design. Also, many of them have a contoured handle with rubber grips for better stability when your hands are wet or greasy.
None of the tools, no matter how expensive, works silently. But that does not mean you’ll have to settle for loud irritating noise. There are a few great options that produce low noise. And such models are an excellent choice for professional use where you have to change a bunch of tires everyday or work on a job site.
What does “Impact Per Minute” Mean?
Impact per minute or in short, IPM means how many times the hammer will strike the anvil. While it is not a great deal for an air impact wrench where the power is delivered via an air compressor, IPM is an important factor when buying a cordless impact wrench.
How do I use a 1/2 inch air impact wrench?
Using an air impact wrench is extremely easy even if you’re using it for the first time. You just need to connect the tool to a reliable air compressor, set the torque(if provided), select forward or reverse settings. Then place the anvil on the lug/nut/bolt and press the trigger. The air compressor operates the motor which then delivers only the set torque for smooth operation.
Lubrication is important before operating any air impact wrench. While many tools come completely lubricated to be used right out the box, you need to oil some before use. Proper lubrication will ensure flawless operation of the tool and cause fewer vibrations.
