The 5 Best Pneumatic Impact Wrench [2019]

Best Pneumatic Impact Wrench 2018 Reviews

If you have ever experienced trying to loosen a large, fretted or corroded fixing, then you know how hard it is to work in tight spaces. At awkward angles, bolts can be extremely difficult and time consuming to fit or remove.

Skinned knuckles, broken tools, and jobs taking hours longer than you had planned, all contribute to the frustration. Even experienced professionals, such as fitters and mechanics, will experience these problems on a regular basis.

Using a pneumatic impact wrench solves both these problems. It is capable of delivering a much larger force than you would normally deliver excluding added advantages.

The wrench helps in faster removal and attachment of bolts and nuts, even those that may be challenging to remove due to their location or their fastening.

Therefore, if you can relate to what I said earlier, you would want to read this article on pneumatic impact wrench reviews.

Where are Impact Wrenches Used?

The use of impact wrenches is wide, with the uses including car improvement, preservation of large and factory machines, major construction projects, and any other instances where you need large force outputs.

Impact wrenches are available in every standard socket wrench size, from small ¼” drive tools for small assembly and disassembly, up to 3½” and larger square drives for major construction. They are some of the most commonly used air tools.

What to look for?

Good pneumatic impact wrenches generate more force than perceived. Because commercial use is often in heavy work areas where the equipment itself takes a few hard knocks, you should check that the casing is as sturdy as the guts.

Make sure that your impact tools have a half-inch space since fewer gaps will not allow heavy work without constant improvements. We chose these top rated air impact wrenches because they meet those requirements, and have some additional benefits of their own.

You will also need a good enough air compressor for impact usage, as well as a high-quality hose that is durable . If you frequently work around vehicles, make sure to purchase a protractible pneumatic hose as well.

Advantages of Using a Pneumatic Impact Wrench

  • Efficiency:You can enjoy increased efficiency in your work due to the high torque levels. Pneumatic wrenches generate more force, compared to electric wrenches.They also produce very high-pressure levels that have powerful and quick results. The generation of high force levels also helps you to conduct heavy work levels in short periods.
  • Versatility:With the pneumatic wrench, you will be able to undertake a wide range of activities. Most models have a flow regulator that regulates airflow in both directions.
  • Ease of Use:One of the major distinguishing features of air wrenches is their small size and their lightweight nature, mainly because their components and power source are contained in the air compressor.Electric wrenches, on the other hand, have their parts in one heavy and big unit . Pneumatic wrench sizes, therefore, allow you to work freely as compared to the other wrench types.
  • Durable:The pneumatic wrench is both a durable tool and a low maintenance appliance as well. This is partly because it has fewer moving components than other tools.It also does not have the motor feature characteristic of electrical tools, instead relying on an air compressor to power it.
  • Dependable:Once you have the cylinder of compressed air, you can start work. Besides, compressed air is a cheap fuel for running tools compared to electricity or natural gas.

Which type is right for me?

Of the three types of the impact wrench, air, electric and cordless, each has its advantages over the others. Originally, there were not many varieties of wrenches, with only pneumatic ones in the market, and used mostly by mechanics to detach and repair lug nuts.

Air Impact Wrench

Depending on the model, air tools are powerful, fast and robust making them ideal for use in a professional environment. However, they do require a large volume, high-pressure air supply to operate and regular maintenance, which means they are not suitable for infrequent or home use.

Corded Electric Impact Wrench

The corded electric wrench is also powerful and fast (again, depending on the model) but is less robust than the equivalent air tool.

A cord making it difficult to move around a workspace too attaches it and, of course, you cannot use it in the absence of a mains electricity supply. However, it can be less expensive than an air or cordless impact wrench, making it an attractive choice for home use.

Cordless (battery powered) Impact Wrench

Perhaps the most sought after; particularly in recent years as the technology has improved – cordless (battery powered) impact wrenches.

A good pneumatic impact wrenches deliver performance approaching that of an equivalent air tool but without the additional infrastructure.

They are also completely portable and the absence of a cord means they can easily move around a workspace. Unfortunately, they are often the most expensive and can be relatively heavy due to the weight of the battery packs.

At present, air impact wrenches remain the most popular with professional mechanics but, as technology continues to improve, the cordless impact wrench will become increasingly popular, less expensive, and ultimately dominate the market.

How to Choose a Pneumatic Impact Wrench

Throughout our pneumatic impact wrench reviews, you may not be sure what to pick. When in doubt, always go for the larger capacity. It is very difficult to specify the exact size of fitting because it is a function of the torque rather than the size and affected by the condition of the fixing.

A corroded or fretted fixing, for example, will require significantly more torque to release it than a new, clean fixing. Another tip for selecting the right size of impact wrench is to consider what size of sockets you would normally use with a 3/8” or 1/2″ drive.

Other considerations such as design, comfort and socket retention system are self-explanatory and should become clear from reading the reviews.

  1. Check the torque needed for your application and select your tool accordingly
  2. Look at your compressor and your airline network: make sure you will meet the airflow requirements and that you have the right accessories. All the information you need is in the operator manual, provided by the tool’s manufacturer, or contact your distributor for any support.
