Buying guide

Power

The amount of power that you need will depend on the jobs that you plan to undertake. If you’re looking to unscrew bolts and lugs that typically refuse to move, you will need an air impact wrench that comes with a lot of torque. The higher the torque, the greater the ability to loosen and ultimately remove those stubborn lugs.

If you don’t need to use a lot of power, and you simply want to get some light jobs done, it may be worth your while opting for an air impact wrench that has a little less power. If you’re not sure how much power you’re going to need, try to opt for an impact wrench that gives you approximately 600 ft-lbs, as this seems to be the average, and perhaps the best option to go for.

You may want to think about borrowing a friends impact wrench just to see how you get on with it. Make a note of the make and model, and see if it works well for you. If the wrench you’re borrowing is more than a few years old, chances are there’s a better model on the market right now, and it might offer you even more torque.

If you don’t know anyone who has their own impact wrench, ask a mechanic or someone who works in a hardware store, as they may be able to help you out.

Should it be cordless?

If you need to use an air impact wrench in a number of different places, it should ideally be portable. Dragging short cords around your home/garage/workshop can sometimes be a little dangerous and cumbersome. A cordless impact wrench will be so much easier to use, allowing you to move from place to place as you wish, when you wish, however they don’t always have very much power. This is where an air impact wrench can come in and make all the difference.

One little piece of advice that you may find useful is that the right air impact wrench for you may be the wrong impact wrench for someone else. If you need to use a wrench that is ideal for heavy duty jobs, you may need a completely different model to your neighbor’s wrench that is only used around the home from time to time.

Price

The price of an air impact wrench can vary depending on where you buy the product, who the seller is, and if there are any deals currently taking place. If you’re looking for an air impact wrench that offers you a lot of power and RPM, you should be prepared to spend a little more. If you’re looking for a budget product, you may end up paying less than $50 for it, but it may not have the torque or RPM that you need.

Pay what you can afford to pay to ensure you get the most amount of power for your money. If power is not important to you, simply look for an impact wrench that has a lot of RPM and a good reputation, chances are it will work well for you.

Questions

What makes it different from the impact wrench?

Air impact wrenches need to be connected to an air compressor, otherwise they won’t be able to work. Connecting them to an air compressor can make them very portable as compressors typically have long cords or leads. Cordless impact wrenches typically don’t have very much power, so they might not be up to the serious jobs that you need to do, especially as they tend to offer just half of the torque that air impact wrenches have.

How does it work?

An air impact wrench, also known as a pneumatic wrench works by using a twisting motion so that bolts and fasteners are freed. Although different models and brands can differ in how much torque they have, they all pretty much work in the same sort of way.

The air impact wrench works by creating and then storing energy in a rotating mass, before releasing it into the output shaft. This amount of energy puts a lot of force onto the lug or bolt that you’re trying to loosen and remove, thereby making it so much easier for you to undo those stubborn bolts that have previously refused to move.

The bolt that you are trying to loosen or tighten is moved intermittently when the air impact wrench is driving it forward, or backwards. Because the RPM on air impact wrenches is so quick, you won’t notice those brief moments when the bolt or lug is stationary. The quicker the RPM, the quicker your bolt is likely to tighten or loosen.

What do you use them for?

Many people choose to use an air impact wrench when they are fixing cars. Mechanics tend to use them everyday as they can effectively remove bolts that hold tires in place, and bolts that are located elsewhere on a vehicle. Occasionally only an air impact wrench will do the job required, simply because many bolts may need to be loosened or tightened, or they have previously proven too hard to remove.

But this tool is not only used in commercial garages, those who work in the construction industry also tend to use an air impact wrench, as powerful wrenches are often required to fix bolts in place during the construction process.

Some factories use this type of tool on their production line, as they have proven to be a quick and effective tool when a job needs to be done quickly.

What else do you need if you get an air impact wrench?

If you intend to purchase an air impact wrench, you will need to have a source of compressed air. Air compressors can be quite large, which means you will need to make sure you have enough room for it. Air compressors are not necessarily too costly, but some can be noisy, so you may need to wear ear protection if this is the case.

Another vital piece of equipment that you will need is a pair of protective goggles. Bolts and lugs can occasionally become loose and get flung through the air because of the amount of energy that is used to loosen them. It is therefore very important that you wear a pair of safety goggles that will help to protect your eyes from bolts.

You will also need to think about wearing a pair of gloves while you work, as your hands may slip from time to time, and you may come in contact with some of the wrenches moving parts.

Lastly, you will also need to purchase some oil, so that you can keep your wrench moving nicely. Some air impact wrenches are sold with small bottles of oil, whereas others are not. In any case, make sure you have plenty of oil, and remember to apply some oil everytime you use your air impact wrench.

Conclusion

The right air impact wrench for you will depend on how much power you need it to have, what your budget is, and of course, what you need it for. There are many different air impact wrenches on the market today, but we are confident that you will find the right tool for you from our list of the best air impact wrenches.
