What is an Impact Wrench?

If by now, you still doubt if an impact wrench is what you need for your job, then this section and the next is for you. Let’s talk more about this impact wrench and what make it different from other tools, particularly, from impact drivers.

An impact wrench is also known as an impactor, impact gun, air wrench, air gun, rattle gun, or torque gun.

Popular Mechanics explained that an impact wrench is primarily a high-torque power tool that fits standard 1/2” socket that are usually used for loosening lug nuts from cars and trucks. Impact drivers, on the other hand, can be used for lighter tasks such as inserting screws in your house, and usually has a 1/4” hex opening.

The high-torque of impact wrenches originates from an internal hammering mechanism that executes powerful concussive blows in seconds. With this capability, impact wrenches are usually used in automotive repair, maintenance of heavy equipment, product assembly, major construction projects, and other tasks that require high-torque .

Types of Impact Wrench

Although all five products we presented above are cordless impact wrenches, there are actually two other types that you may choose from. So, in this section, we’ll present and differentiate these types of impact wrenches starting of course with the cordless.

Cordless Impact Wrench

This type is the most popular choice in the recent years. Despite being more expensive than other types, the fact that it is battery-powered makes it more convenient for most works. The absence of a cord means it is more portable and can reach even those areas that may be too far from a power outlet. Yet, it remains to have high voltage that will still allow it to do the job.

The downside, however, is the additional weight brought by the battery packs. So, in general, the cordless impact wrenches are the heaviest ones.

Air Impact Wrench

Next is the air impact wrench. This type is one characterized with much power, speed and strength. This combination of qualities makes air impact wrenches ideal tools for professional works.

One familiar example of impact wrench users is the race mechanics. They use air impact wrenches to remove and refit wheel nuts.

To operate and maintain these high impact wrenches, you would need large volume, high pressure air supply. This is another reason why this type is more for professional jobs and not for home use. You would also need to connect these wrenches to a compressed air supply through an airline, making its portability limited.

Electric Impact Wrench

Last are the electric impact wrenches. They are very much similar with the cordless impact wrenches. Their primary difference is that instead of being powered by a battery pack, electric ones need a direct electricity supply. The cord that connects the tool to the power source therefore limits the areas that can be accessed by this type of wrenches.

Nevertheless, electric impact wrenches are equally powerful and fast as those cordless impact wrenches. This type is also the least expensive, making it the most popular choice for home use.


Despite being less widely-known compared to other power tools such as the drills, impact wrenches sure proves to be a great help as well in your tasks, whether professional or DIY.

And, when it comes to power tools, you certainly won’t go wrong with Dewalt. Not only are they powerful enough to help with the tasks they are expected of, Dewalt power tools are also almost indestructible.

Dewalt offers many different impact wrenches that would suit the task at hand and your budget. Read through the specifications first to make sure that what you are planning to purchase can do the job.
