The Best Pneumatic Impact Wrench Reviews – Best in 2020

An air impact wrench is known with many names like air wrench, air gun, rattle gun, impact gun, windy gun and sometimes they are also called torque gun. This is a very powerful tool that delivers high torque with the minimum exertion to the users. This product actually works by ensuring intensity in a rotating pneumatic impact wrench

Air impact wrenches are the amazing products that are used for plenty of industrial purposes. In industrial fields, high torque products are required so these are wildly used in automotive repairing, heavy instrument maintaining, major manufacturing projects, product assembling and many more industrial fields.

An air impact wrench is available in different sizes. ¼ inch air impact wrench is mainly used but the best pneumatic impact wrench is one that suits well to your needs fully.

Air Impact Wrench vs Cordless Impact Wrench

Here we will try to differentiate between air impact wrench and cordless impact wrench for the proper understanding of the readers. We can differentiate these two products on the basis of few key points which are as follow:

  • Weight: An air impact wrench is a lightweight product as compared to the cordless impact wrenches. This is so because air wrenches are simple tools and they use air for power. A cordless impact wrench with the same power is always bulky as compared to the air impact wrench because air wrench has no internal motor and it does not involve tons of wiring.
  • Power: Air impact wrenches are definitely more powerful than the cordless impact wrenches. In the last few years, a lot of models of cordless impact wrenches have been introduced but they are still not as powerful as the impact wrenches are. The torque of air impact wrench is quite high as compared to the advanced models of cordless impact wrenches.
  • Maintenance: Maintenance is not an uphill task in both designs. In the case of cordless impact wrench, there is no need of maintenance as there are no brushes to change out. But an air impact wrench needs some maintenance. The compressor of air impact wrench needs oiling, proper draining of air tank and you need to make sure that the tank holds air properly. After many years of use, you are required to change the tank too. So in this case, cordless has some advantage over air impact wrench.
  • Convenience: The convenience factor is very important. In case of air impact wrench, you need to attach a hose with tool and compressor too before doing any task whereas cordless impact wrench is a battery-powered product that is ready to use once its battery is fully charged. So cordless impact wrench can be more conveniently used as compared to the air wrench.
  • Price: Air impact wrench is a simple tool that does not require motor and wiring but it needs compressor and hose. In the same way, cordless impact wrenches come with charger and batteries. From price point of view, you will not experience much of a difference between the two products.
  • Portability: Feature of portability is generally high in cordless impact wrenches. As these are battery-powered products so they can be carried anywhere without any problem. In case of air impact wrench, you need to set hose with tool. So feature of portability is comparatively low in air impact wrenches.

Some Important Things to Consider Before Buying Best Pneumatic Impact Wrench

Well, it is an important question which many people ask that why buy an air impact wrench when you can do the fastening and screw tasks with an electric drill. But you must know that an air impact wrench gives a lot of power which an electric drill cannot provide.

Let’s have a look on important things which one must consider before buying an air impact wrench.

There are three types of air impact wrenches:

  1. Pneumatic Impact Wrench: These are old school wrenches which need air compressor as they run on compressed air to aid for their power source.
  2. Electric Impact Wrench: These are both corded and cordless impact wrenches and as their name state, it needs electricity to power the machine.
  3. Hydraulic Impact Wrench: These are not commonly found in the market but they definitely yield more torque than pneumatic impact wrenches.
  • Power: Before buying an air impact wrench, always consider its power first. Choose a wrench with sufficient power which you will actually need for completing your tasks.
  • Sound: With air impact wrenches, even small wrenches can be very noisy, so make sure you choose the one with lower sound levels.
  • Grip: Always give due thought to grip as you will be holding the wrench for longer hours, so make sure that it is convenient to hold and work with.
  • Hammer Mechanism: Hammer mechanism is highly important to analyze the performance of an impact wrench as it needs little torque before the hammer is allowed to move/spin separately from anvil. Twin hammer design in air impact wrenches has also great value as it allows the use of two hammers at the same time providing high efficiency at work.

So, before buying an air impact wrench, you should keep these above-mentioned points in your mind so that you invest in the best pneumatic impact wrench.
