Pneumatic impact wrenches are a very important part of any toolset. They can be used for everything from automotive repair to plumbing work and anything in between. 

If you’re looking for the best pneumatic impact wrench, then you’ve come to the right place! In this blog post, we’ll review 7 different models that we feel deserve recognition. We will cover their strengths and weaknesses and give our opinion on which one is the best value for your money.

Impact Wrench

An impact wrench is not just for automotive repair. These wrenches are also used in many types of construction, plumbing, and other industries where machinery needs to be fastened securely or taken apart with ease.

If you are new to this type of wrench, you should know that it differs from your standard power tool. While an impact wrench is still similar to a drill in some aspects, it has one major difference: force and speed.

Pneumatic impact wrenches use compressed air to create powerful vibrations, which allow them to exert pounds of torque for loosening and tightening nuts, bolts, screws, and other fasteners.

In order to really understand how an impact wrench works, it’s important to have a basic understanding of physics.

In almost every type of power tool, the motor creates rotational motion, which is then transferred through gears or belts in order for you to get the right amount of torque applied at whatever you are working on. This is the standard way most power tools work, but this process happens in reverse with an impact wrench.

Instead of gears and belts creating rotational motion to turn a fastener, it’s actually done through a series of internal weights which accelerate very rapidly before coming to a stop against a backplate inside the tool itself. This rapid acceleration and deceleration create powerful vibrations which allow you to quickly loosen or tighten nuts, bolts, screws, or other fasteners.

While this is a very simplified explanation of how impact wrenches work, it will give you an idea of why they are able to exert so much force at such high speeds, they may be different than your standard power tool, but they are still very easy to use and understand.

            Types Of Impact Wrenches

            Impact wrenches are available in a wide range of different types. The most common ones are pneumatic impact wrenches, electric impact wrenches, and gas-powered impact wrenches. Here is a quick rundown on each one:

            Pneumatic Impact Wrench

            These are the standard type that use compressed air to create powerful vibrations for loosening or tightening nuts, bolts, screws, and other fasteners. 

            They are generally more affordable than electric or gas-powered impact wrenches, but they do require an air compressor in order to provide the necessary compressed air which is used for power. 

            These types of impact wrenches can offer a lot of torque depending on how much psi your particular tool has available.

            Electric Impact Wrench

            These are the most common type of impact wrenches available today. They use electricity to create rotational motion typically done by a motor-driven belt or gear system. 

            Electric models usually have less torque available, but they can be used anywhere without needing access to an air compressor or other power source besides standard 120V house current.

            Gas-Powered Impact Wrench

            These types of impact wrenches are powered by gasoline and can be used anywhere. They usually have the most amount of torque available and some models even come with a two-stage trigger which provides more power when you need it for stubborn nuts, bolts, or other fasteners.

            On the other hand, If you are looking for a smaller and lighter version of the impact wrench you can try the butterfly impact wrench. These wrenches are very small and lightweight, but they can still produce enough power to get the job done.

            Picking The Right Impact Wrench

            Pneumatic impact wrenches are not all the same. While they may look similar on the outside, they have their own unique strengths and weakness, making them great for some applications but less than optimal for others. 

            It’s important to really take your time when picking out an impact wrench because you don’t want to end up with a tool that doesn’t meet your needs or isn’t capable of doing the job you need it to do.

            Each of these impact wrenches is great in some ways and not as good in others; this makes choosing one even more difficult because there are so many factors to take into consideration. 

            One of our main goals here was to create a list of the best pneumatic impact wrenches for different types of applications, users, and budgets. We feel confident that you will be able to find one which works well for your needs!

            Here are some basic guidelines on what factors to consider when choosing an impact wrench:

            Torque (ft./lbs.)

            Whenever possible try to include a wide range of torque options for each impact wrench to ensure something which would work well in most applications.

            Maximum RPM

            Some pneumatic impact wrenches have higher maximum rotations per minute than others, and this is generally the result of how they are designed internally. If you need an impact wrench with high RPM, you need to pay attention to the maximum RPM of each one.


            Impact wrenches can get pretty heavy, especially if they have high torque and/or a lot of horsepower in them. This is something that users will want to keep in mind when choosing an impact wrench because it could affect how long they are able to comfortably use it.

            Drive Size

            One of the most important specifications that you should look at is what size drive each impact wrench has. 

            If your fasteners are a different size than their drive then you won’t be able to tighten or loosen them and will need an adapter in order for this tool to work properly. It’s also worth noting that impact wrenches which have a quick-release mechanism built into them are much more convenient and easy to work with.

            Ease of Use

            There is nothing worse than an impact wrench that’s difficult to use or operate; thankfully all the options here are designed as ergonomically as possible so you won’t ever feel uncomfortable using them.


            Since impact wrenches are designed to be used in harsh conditions they need to have a high level of durability and overall construction. Considered this when choosing the options for our list, but you’ll also want to look at what materials each one is made out too.

            This should give you an idea about some of the factors you need to consider when choosing an impact wrench. As long as you have a good idea of what your needs are and what type of application it will be used, we’re confident that one of these options will work well for you!

            Pneumatic Impact Wrench FAQ’s

            What’s the difference between impact and air wrenches?

            An impact wrench is a term that refers to both pneumatic and electric versions of these tools; an air wrench refers specifically to pneumatics.

            Since there are many different types each have their own advantages, disadvantages and specific uses so it’s important not to confuse them with one another.

            Are impact wrenches expensive?

            Why do some impact wrenches have a quick-release mechanism?

            A quick-release is an extremely convenient option because it allows you to quickly and easily switch sockets without having to fiddle around looking for them or using any tools. This can save you a lot of time and effort which makes these options well worth it.

            What is the average size of an impact wrench?

            Impact wrenches come in a wide range of different sizes and styles, making it easy to find one that will work well for your specific needs.

            The most common drives are ½ inch, ¼ inch, and ⅜ inc, but larger options are also available too if you need something more powerful.

            What’s the best way to use an impact wrench?

            There are a wide range of different applications for impact wrenches, making them great tools to have around the house or garage.

            Whether you need to use them on your car, truck, motorcycle, or some other type of vehicle they can really come in handy and make it much easier to work with certain things by hand.

            What’s the difference between electric and pneumatic impact wrenches?

            There are two main types of these tools: electric and pneumatic. Pneumatics use compressed air to power the tool, while electrics need a battery or some other source of electricity in order to operate.
