The attractive thing about this unit is, however, its forward-reverse button. It makes operating the wrench easier and suitable for newbies.
The company claims that the product is quiet, and supports that with the claim that it produces only 86 dB of sound. In reality, the wrench is a bit noisier, but that is not unusual for air units, and it shouldn’t be a deal-breaker. The unit is lightweight, which makes it great to use on the go. It also makes it more manageable to transport from one job site to another.
3. AIRCAT 1150 Killer Torque 1/2-Inch Impact Wrench

If you are looking to buy an air impact wrench, keep reading to discover everything you need to know about this tool before finalizing the purchase.
What to Consider When Buying a Pneumatic Impact Wrench?
How Much Power Do You Need?
The question that you should answer first is how much torque you will need. If you are a DIY enthusiast and a user who plans on operating a wrench for small home improvement projects, a compact tool with up to 600 ft-lbs of torque can be enough.
Alternatively, if you are a professional and plan on using the tool for various heavy-duty applications, you may need some extra torque. In that case, consider the units that go up to 1,300 ft-lbs
Is the Grip Comfortable?
After all, it is all about comfort, especially if you plan to use the tool for hours every day. That is why most manufacturers have ergonomic handles that minimize fatigue even when working with the tool for a long time. A rubber grip can make the operating easier, too, because it can prevent the wrench from accidentally slipping from your hand.
Do You Need a Light Unit?
While we are on the topic of comfort, let’s discuss the wrench weight. In general, air guns are not that heavy. However, some units are heavier than the others, but they usually come with extra power and durability. If moving the tool around and keeping it portable is important to you, try to keep the unit you buy as light as possible.
Can You Adjust the Power of the Wrench?
Adjusting the power of the wrench is vital when it comes to controlling the tool and maximizing each efficiency. Many units these days have that feature available and allow you to choose between multiple settings. It is a great way to ensure everything runs smoothly, and you don’t risk damaging a bolt head.
Most Important Air Impact Wrench Features and Specifications
The most important question you can ask is – what features should the best impact wrench have? Here are the crucial specifications that you should consider:
- Drive size – what you want to ensure is to suit the drive size to the applications you will be working on most frequently. If you plan to loosen 10-mm bolts, you won’t need a one-inch air gun.
- Torque – believe it or not, buyers often think they will need more power from the wrench than they will need. If you want to make a smart investment and not waste your cash on an unnecessarily strong unit.
- Speed – some manufacturers choose to tell you the no-load speed of their wrench while others will also reveal what is the speed under load. These statistics are measured in the number of rotations per minute. While it is nice to have a faster wrench, it is more important for it to be powerful.
- Impacts per minute – the number of blows that a wrench can give per minute. It may be important as it may enable you to torque the bolt more tightly, and even more crucial because it can loosen tightly-screwed bolts.
- Weight – if you are all about portability and easy operation of the unit and you are willing to sacrifice some power and durability, you should look for the lightest wrench out there. Alternatively, if you want a strong and powerful tool, you may need to pick units that are a bit heavier.
What to Consider to Buy the Best Air Impact Wrench for Lug Nuts?
A lug nut is nothing else than a fastener that is used to secure wheels on your car or other vehicles, including trucks and vans.
One of the most common uses for an impact wrench it to tighten or loosen a lug nut. The general rule is the more torque you have, the better. However, even average-strength air guns should be enough to change a standard lug nut.
When we say standard, we mean one that is not jammed or too tight. In case of those, you may need a particularly strong wrench.
Best Air Impact Wrench for Changing Tires
When it comes to changing tires, the crucial thing to consider is that the pneumatic impact wrench you choose also has a reverse feature. That is because changing a tire will require your tool to make both loosening and tightening actions.
As for the torque, you shouldn’t worry too much as the majority of air guns can handle changing a tire. It will depend on the tightness of the bold and whether or not it is jammed, but even the average wrench should ensure that you change a tire effortlessly,
How Does an Air Impact Wrench Work?
As the name suggests, a pneumatic impact wrench uses air as the power source to run the unit. That means you should attach it to a compressor and utilize air pressure to operate the tool.
An air gun provides the necessary rotation by providing high-speed twisting movements that result in a particular action. That action is either tightening or loosening, and it depends on the direction you choose. It is how an impact wrench can be used for both assembling and disassembling applications.
How to Use an Air Impact Wrench?
Take a look at the quick overview of how you can start using your impact wrench today:
- Step 1. Assemble the unit by following the instruction manual.
- Step 2. Choose the appropriate pressure level for your tool. Double-check that everything is connected properly. Test the wrench to see the starting direction of the tool. You may have an option to reverse the direction if necessary.
- Step 3. Find the speed adjustment settings on the wrench – it can be a button or a dial. Make sure the environment is safe and start operating the tool. When stopping, make sure to wait until the tool stops rotating patiently.
How to Adjust Torque on an Air Impact Wrench?
The torque that your pneumatic impact wrench will use depends on the potential of the tool itself, but also the available air pressure provided by the compressor. Some wrenches have an air regulator that you can use to adjust the torque.
If your tool does not have a regulator, you will have to adjust the pressure on the compressor itself. Keep in mind that reducing the compressor’s overall pressure might affect other tools that use it.
FAQs & Answers

- Q: Is It Better to Use an Air or Electric Impact Wrench?
A: In the electric VS air impact wrench battle, the pneumatic wrenches take the win because they are more powerful. On top of that, they are a more affordable option, although the price depends on the unit. Air impact wrenches also tend to be light and compact, which makes them convenient and portable.
