What Size Impact Wrench Do I Need?

Impact wrenches are most commonly found in mechanics shops, used to quickly loosen the lug nuts on cars and tires. The standard size for an impact wrench is ½ inch, which fits most cars and small trucks. 

If you are mostly using an impact wrench for your car, then a ½ wrench is your best option. However, a ¾ impact wrench will likely be needed if you plan on working with heavy equipment and large truck tires. 

What Are Impact Wrenches Used For?

Impact wrenches have long been used by pit crews during races to quickly loosen and tighten lug nuts. Outside of the racing pit, they are one of the best tools used for lug nuts that are tightened to high torques. 

Impact wrenches are used when you need a tool that can deliver a lot more torque than a hand wrench. They are useful for quickly changing tires on cars and trucks, but they are useful in just about any situation where you’re dealing with high torque lug nuts. 

What Makes These the Best Of the Year?

The air impact wrenches featured here all stand out for different reasons. Some, such as the Aircat, is pure power and performance, making them great options for professional mechanics who need a serious tool that won’t let them down. They’re also built to last, giving you years of high-end performance. 

Others feature more modest power but come with an easy to use design that makes them great for home use. These wrenches can help you change a tire in a pinch, making the process quick and easy. They’re also compact, so you can store them in your garage without taking up too much room. 

Even the most affordable wrenches listed here still offer enough power and precision to satisfy demanding mechanics. The Campbell Hausfeld gives you as much torque as you’d normally find in wrenches that cost two to three times as much. 

All of the air impact wrenches here are also designed with comfort in mind. They’re tools that you can use all day without too much wear on your arms.

Buyers are also surprised by the wrench's lightweight build, given how much power it has. They report that the wrench held up well when used in tough conditions, taking bumps and bruises without any drop in performance. 

Why it Stands Out to Us

Power and precision. If you’re looking for a ½ impact wrench that can handle just about any job, the Ingersoll-Rand is about as good as it gets. With a maximum torque of 1350 ft.-lbs., this is a powerful wrench built for professional mechanics. At just 4.63 pounds, it’s also one of the lightest reviewed here, despite being one of the most powerful. 

Who Will Use This Most

Built to handle high torque applications, the Ingersoll-Rand is mainly designed with professional mechanics in mind. It has a bit more punch than what most occasional home users would need, and it’s also more expensive than many impact wrenches. It’s a great option if you need professional-grade performance. 

Bottom Line

When it comes to ½ inch impact wrenches, it’s hard to beat the Ingersoll-Rand. This wrench delivers 1350 ft.-lbs. of torque in a compact, durable build that feels great in your hand. It’s a serious wrench, and you’ll have to pay a premium for it. But it’s well worth the cost for mechanics and serious car enthusiasts. 

Best ⅜-Inch Air Impact Wrench:

The wrench is a favorite of mechanics, who say that it delivers even more power than you would expect. They report that the wrench’s ergonomic design is comfortable and doesn’t cause their hands to tire out. 

Why it Stands Out to Us

With more power than just about any other ⅜ wrench in its class, the Ingersoll-Rand offers a versatile, compact tool perfect for working in tight spaces. It’s also one of the lightest wrenches reviewed here, so your hands and arms won’t wear out from using it for long periods. 

Who Will Use This Most

Since the Ingersoll-Rand is a ⅜ inch wrench, it’s a great option if you need a tool that can reach tight spaces. Its compact build makes it useful for mechanics who need to work with small parts in the engine. Although tailored to mechanics, the wrench will also suit anyone who works with cars. 

Bottom Line

If you need a powerful ⅜ wrench, the Ingersoll-Rand is your best option. It’s light, durable, and comfortable to use. Its compact build means you can use it to work on engines, and it offers an excellent grip that will loosen just about any lug nut. Whether you’re a mechanic or working on cars at home, should last you for years. 

Best Air Impact Wrench Under $100:
Ingersoll Rand 236G 1/2-Inch Edge Series Air Impactool

Ingersoll Rand 236G 1/2-Inch Edge Series Air Impactool, Silver


  • Works quickly
  • Gets great grip on lug nuts
  • Excellent value for the money
  • Durable build that holds up over the years
  • Small and lightweight for comfortable use


  • May not be powerful enough for big tires

What Recent Buyers Report

Buyers say that the Ingersoll-Rand 236G offers great value for the money, giving them enough torque to quickly change car tires. They say that the wrench has a comfortable grip that is easy to hold for long periods. Some buyers report that the wrench is a bit underpowered, although it performs well given the price. 

Why it Stands Out to Us

The 236G isn’t going to blow you away with its performance. But where it stands out is with its price. This is one of the best deals that you’ll find on an impact wrench. It’s a durable tool that should last you years, and you’ll get precision and performance that you would expect from a wrench twice the price. 

Who Will Use This Most

The 236G isn’t the most powerful air impact wrench here, delivering around 450 ft-lbs of torque. If you’re a mechanic, this may not be enough for some applications, so the 236G is better suited for more casual users who need a solid wrench to change tires and fix up their car. 

Bottom Line

If you’re looking for a basic air impact wrench that will give you good performance for a great price, the 236G is an excellent choice. It’s not high powered, and it isn’t well suited as a go-to tool for professional mechanics. But it still gives you more than enough torque to quickly handle lug nuts and change tires. 

Best Air Impact Wrench for Home Use:
Craftsman 1/2-in. Impact Wrench 9-16882

Craftsman 1/2in. Impact Wrench 9-16882


  • Comfortable grip
  • Fairly quiet operation
  • Excellent for home use
  • Easy to handle and transport
  • Loosens and tightens lug nuts quickly
  • Great value for the performance you’ll get

What Recent Buyers Report

Although the Craftsman doesn’t perform as well as other wrenches on this list, buyers say it can still apply enough torque to easily change tires. Some also say it’s not the most durable and may start to have issues if it gets banged up. These complaints aside, buyers say it’s a great entry-level wrench for use around the house. 

Why it Stands Out to Us

For the money, you won’t find a better air impact wrench. No, this isn’t a wrench you’ll find at a mechanic’s shop. But it still packs enough power to easily handle a tire change in the driveway, which is all a lot of people need. It’s also fairly light, making it easy to use without wearing out your arm. 

Who Will Use This Most

This is a wrench that’s tailored for home use. It’s affordable, lightweight, and compact, so it’s great to have to lie around the garage if you need to change a tire in a pinch. Mechanics will probably need something with a bit more power, although it will still work if you just need to change a few tires on a small car. 

Bottom Line

The Craftsman isn’t going to win any awards for precision or power. But that’s not what it’s designed for. This is a wrench that’s made to be affordable, giving you all of the basics you need for at-home car maintenance. It’s a great option if you need a simple wrench for occasional use around the house.

Some buyers say that the wrench required a fairly large air compressor to get enough air, although others reported that they had no issues with a small air tank. 

Why it Stands Out to Us

The Campbell Hausfeld is one of the cheapest wrenches reviewed here, while still delivering over 550 ft-lbs of torque. It’s hard to find this combination of affordability and performance, making it one of the best entry-level air impacts wrenches out there. 

Who Will Use This Most

Campbell Hausfeld is built for a range of different uses. It’s cheap enough that you can buy it to change tires every now and again around the house, but it has enough power that mechanics can rely on it. It’s a great wrench if you work with small to medium-sized cars and don’t need torque above 600 ft-lbs. 

Bottom Line

The Campbell Hausfeld is simply one of the best deals you’ll find on an air impact wrench. It comes with a discount price tag while giving you the performance of a top of the line wrench. It’s a great addition to any home garage toolkit or mechanic’s shop. 

Types of Air Impact Wrenches

There are different types of air impact wrenches available. Here they are. 

Air Impact Wrenches

Air impact wrenches are the most commonly used type, delivering more power than most impact electric powered by electricity. 

Since they don’t have a battery, air impact wrenches are one of the lightest types of wrench, so your hand won’t wear out with extended use. 

To use an air impact wrench, you’ll have to connect it to an air compressor, which makes them less portable than battery-powered wrenches. 

Corded Electric Impact Wrenches

These impact wrenches are powered by a cord that you plug into a wall outlet. Although they don’t usually pack as much power as air-powered wrenches, they are one of the best options if you don’t want to buy an air compressor. 

They’re great for home use, and many still have enough power to be used by mechanics. However, not all corded wrenches will have enough power to handle lug nuts on heavy equipment. 

Battery Powered Impact Wrenches

Battery-powered impact wrenches are one of the best choices if you need a portable tool for jobs on the road. You don’t need an air compressor or an outlet, so you can change tires roadside without any issues. 

The main downsides to using these wrenches are the weight and the lack of power. Most battery-powered wrenches are fairly heavy, so they can fatigue your arm after prolonged use. They also don’t have as much power as other types of wrenches, so they aren’t the best choice if you need to handle high torque lug nuts. 


Finding the right air impact wrench can be difficult. That’s why we’re here. We’ve selected some of the best wrenches of the year in a number of different categories. 

Whether you’re a mechanic looking for a go-to impact wrench or you need a basic wrench for changing tires at home, we’ve got you covered. 

People Also Ask

Here are the answers to some common questions that people have about air impact wrenches.

Which is Better Air or Electric Impact Wrench?

That all depends on how you plan to use the impact wrench. In general, air-powered impact wrenches pack much more of a punch, making them the best choice if you need high-end performance. 

However, electric impact wrenches come with the advantage of portability. You won’t need an air compressor, and many also cordless. 

AIRCAT 1150 Killer Torque

What Size Air Compressor Do I Need For an Impact Wrench?

In general, you should choose an air compressor that has around 1.25 to 1.5 the max CFM of your impact wrench. Before buying a wrench, check the manufacturer specs to see what type of air compressor they recommend. 

Most ½ inch impact wrenches will call for around 4.0 CFM at 90 psi, although you should always check the details provided by the manufacturer. 

How Many CFM Do I Need For Air Tools?

That will depend on the type of air tools you plan on using. With impact wrenches, you should do just fine with a CFM of around 4.0, although ¾ inch wrenches may require an air compressor that can deliver at least 5.0 CFM. 

What is the Difference Between SCFM and CFM?

Both SCFM (standard cubic feet per minute) and CFM (cubic feet per minute) are similar units, and they are usually roughly equivalent to each other. SCFM just gives you the conditions for the measurement. It means that the air compressor gives you a certain number of cubic feet per minute at 68 degrees Fahrenheit and standard atmospheric pressure.
