A pneumatic impact wrench has a lot of advantages. It is more powerful and can handle more complicated tasks without compromising safety. Moreover, it can be used by a single person. Unlike hydraulic torque wrenches, this type of wrench doesn't require a pump and specialized oil.
Another advantage of a pneumatic impact wrench is that it can be used in hard-to-maneuver areas. For example, you can use it to fix a tyre in your car or on the side of a road. And it is also ideal for removing bolts in your home. Compared to battery-powered or hydraulic impact wrenches, it has less components and is easier to operate.
Also, most air impact wrenches don't require a lot of maintenance. They only need to be oiled every 20 days. That should be enough to keep them running well for a long time.
However, there are certain disadvantages. One of the biggest is noise. Considering that you're operating a tool that makes a lot of noise, you should definitely wear ear protection.
Another problem with a pneumatic tool is the need to replace the tank. Since it uses compressed air, the tank will eventually deplete. To prevent this from happening, you need to make sure you refill it often.
In addition, you will also need to have a good air compressor on hand. If you don't have access to a compressor, you can get a pneumatic tool with a rechargeable battery. Alternatively, you can buy a high-torque cordless impact wrench.
