Air Impact Wrench – What is it Used for?

Air impact wrench is an important tool that is mainly used for unscrewing and screwing screws and bolts. They are known as air impact wrenches because they work when they are connected to the air compressor as the power supply for these wrenches comes from the air compressor. Using an air compressor eliminates the use of electric current for power supply and thus, these wrenches can be used in all places with complete safety.

Air impact wrenches are widely used today in many industries like automotive repair, product assembly, construction purposes, and heavy equipment maintenance. Usually, these wrenches come with clockwise and anti-clockwise rotations with two or more speeds for screwing and unscrewing stubborn nuts and bolts.

How Does an Air Impact Wrench Work?

Impact wrenches work the best when no other tool is working while removing a tight lug nut from a place or the screw head might be stripped in such a way that prevents the tools from getting a good grip. For all such reasons and more, the impact wrenches work effectively by bringing additional grip and force to the tight bolt and nuts and an air impact wrench is even better as it allows the user to use the impact wrench in every weather conditions and wet places as well.

An air impact wrench gets its power supply from compressed air that applies a strong and sudden twisting motion to the nuts or bolts in short bursts and these short and strong bursts of force that is applied to the stubborn nuts and bolts brings about some movement in them, forcing them to loosen or tighten as per the requirement. The air impact wrenches can be used for both assembling and dissembling of the products. It provides the maximum amount of torque which makes it the most popularly used impact wrench and also considered as the best professional impact wrench.

Why Use an Air Impact Wrench?

An air impact wrench is a power tool that can be used anywhere and in all weather conditions without worrying about electricity. The air impact wrench is designed to deliver high torque output with very less labor by the user as it stores the energy in a rotating mass which is accelerated by the air motor and is suddenly delivered with great force to the output shaft to create an impact on the nuts and bolts. The air impact wrench works best in unscrewing tight screws and bolts because of the high torque that it offers, unlike other impact wrenches. It also delivers excellent performance in screwing nuts and bolts with accuracy and increased security.

Benefits of Using an Air Impact Wrench

Once you learn how to use an air impact wrench, you can benefit the most from it in many ways. Here is a list of the benefits offered by an air impact wrench:

Easy loosening and tightening of nuts and bolts: Most of the times, the user is going to come across a nut or bolt that is extremely tight to remove from the machines and using the usual hand tool for loosening the bolts might not serve the purpose. In such cases, an air impact wrench can make the work easier, safer and would also require less effort while removing a really stubborn bolt or nut. These wrenches are powered by compressed air which delivers a huge amount of force on the nuts and bolts for tightening them perfectly in place also.

Downsides of Using an Air Impact Wrench

To use an air impact wrench you must have a direct connection to some air source or at least have a container of compressed air attached to the tool for making it work. An air impact wrench is useful in removing stubborn nuts and bolts easily with less effort from the user in a very less time. The tool is very powerful but it can be hard to regulate it. The tool works efficiently in removing the tightened or rusted nuts and bolts but removing small pins or other delicate objects with this can be difficult or impossible. If you are looking for an impact wrench that will work on different levels for all sorts of nuts and bolts, an air impact wrench might not be the best choice.

Factors to Consider Before Buying an Air Impact Wrench

While a large and rusted bolt can be frustrating to remove, an air impact wrench can make that work easy for you. It will save your time and labor as well as deliver effective results to make your projects successful and more reliable. Here are some of the factors that must be considered before buying an air impact wrench

The size of the air compressor: This is the most important factor that must be considered while buying an air impact wrench because the air compressor is the power source of an impact wrench. If there is a shortage of power due to a small air compressor, even the most expensive tool will not be able to deliver effective results. Make sure that the air compressor of the wrench you purchase suits your requirements. Its air consumption must be monitored and the compressor must provide air at 90 psi which is the minimum amount of pressure required for the wrench to function completely. If the compressor provides more pressure, it is even better.

The size of the drive: The size of the drive must also be considered while buying an air impact wrench. Many buyers assume that the bigger the size of the drive, the better the performance of the wrench. However, that is not always the case as the drive must not be of any size lesser than that of the nuts and bolts the user will be working on. Before buying the impact wrench, take time and study the size of most of the nuts and bolts that you will be working on. Once you figure out the size of the nuts and bolts, you can understand and purchase the drive that fits best for the size of the sockets that you will be working with.

Power required for making the wrench work: Most buyers underestimate the amount of power that the wrench would require to work efficiently. Manufacturers usually recommend 80-140 ft-lbs for these wrenches, while many users also choose to get the maximum working torque and go for an impact wrench with 220 ft-lbs. There are other factors that must be taken into consideration here, like rust and weathering. If the wrench is going to be used for more purposes other than removing lug nuts, you must look for the recommended torque rating and purchase one that suits you the best.

Torque and speed: While using an impact wrench, it’s the speed and the torque that determines the amount of force you can generate to loosen or tighten a bolt. If you have a higher torque value it can certainly help you manage the larger bolts that are stuck. Since these bolts will require a lot more power than small bolts, a wrench having higher torque will be a good idea to use. In case you deal with different types of bolts, a wrench with the facility to adjust the torque will be a better idea. This will allow you to have a better control over your wrench while tightening your bolts and will also help you in checking the amount of air you should use so that you can adjust it according to your requirement. The speed also plays an important part in how fast you can work on your bolts. With an impact wrench with higher speed, you can easily have an advantage while loosening stuck bolts. But normally if you go for higher speed the torque will be lower. So, the best option will be to buy an impact wrench with higher torque value to work faster.

Dimensions and weight: Although weight and dimension of the wrench do not matter a lot, it’s somewhat important as it will define how hard it might be to handle it. You need to understand the fact that you cannot use a wrench that you cannot handle easily. Some might wish to use a light weighted wrench whereas some might feel okay with a heavyweight one. The dimension of a wrench will play a different role though. It determines how easily you can access a bolt stuck in a difficult position. A wrench with a long enough barrel will help you reach those difficult angles whereas a bulky wrench might not be able to do so. The best thing will be to choose a wrench according to your need. This will ensure that you can get your job done with ease.

Noise level: Well, if you think you can get a silent impact wrench, you are going to be disappointed completely. Technically you cannot have a wrench that does not produce any sound at all that is the reason why you need to use an ear protection while using this type of tool. If you really are concerned about the noise the tool is going to produce, you can opt for a wrench that will produce comparatively lower sound, but still, you will have to use the ear protection while working.

Power: Power of an impact wrench plays an important part in choosing the right tool. In case you are looking for a wrench for DIY tasks, 300-500 ft.lbs of power might do alright. But if you are looking for a wrench for professional work, you have to go for power around 700-800 ft.lbs.

Brand: Buying wrenches from reputed brands will always serve the user the best. They strive to deliver the best air impact wrench with an increased durability. Purchasing your tool from a reputed brand will also help you to get air impact wrench reviews from the previous buyers regarding the wrenches provided by the brand. This will make it easier for you to understand which brand to rely on for buying your air impact wrench.
