An impact wrench is the epitome of power. It is also known as a windy gun, torque gun, rattle gun, air gun, air wrench, impact gun, and impactor.

What does it mean? It is a socket wrench power tool engineered to provide high torque output with reduced user exertion.

What is the purpose of an impact wrench? It is used for tightening or loosening large bolts, lug nuts, and rusted or frozen fasteners. They help users by providing a rotational torque that a regular power driver fails to deliver.

But how does an impact wrench differ from impact drivers? You will need impact drivers to drill long screws into metal or wood; plus, they are easy to use.

In contrast, an impact wrench is the bigger brother of an impact driver. They tighten or loosen nuts or bolts and are heavier and more powerful.

So if you need superhuman effort, you can always count on an impact wrench. These tools will save your muscles from doing the hard work and provide enough torque to move the bolts. Hence, protecting your wrists from injury.

Best Dewalt Impact Wrench: Buyer’s Guide

Dewalt Impact Wrench Buying Guide

An impact wrench is widely used in automotive industries, and it is most commonly used to remove lug nuts. They are also used in large construction projects and the manufacturing of machine tools.

These guns are a powerful tool to tighten or loosen up the large bolts, lug nuts, rusted or frozen fasteners. These tools provide an extremely high rotational torque that a regular power driver cannot deliver.

Suppose you want to loosen a stubborn nut or frozen bolt with a hand wrench. It will not break easily even after constant tries.

But what will happen if you hit your wrench with a hammer? When you hit it several times, the rusted nut will break loose. That’s what an impact wrench does.

To make your work easier, you need a good quality gun! However, choosing a product for yourself from many options can be overwhelming.

However, do not fret! We have mentioned a few things that you should consider before purchasing the top-notch Dewalt impact wrench for yourself.


Most of the cordless guns allow you to swap their batteries since it is external. Make sure that you use the same brand ones. The impact wrench usually requires lithium-ion batteries.

Moreover, a higher voltage battery will give you more power and vice versa. 12-volt impact wrenches require smaller batteries because they are compact tools, fit into tight spaces, and are suitable for smaller tasks.

The 18 and 20 volts impact wrenches do not have massive differences. Usually, 18-volt guns with advanced capabilities and features make them more straightforward to use and versatile.


High power is one of the stellar features of an impact wrench. Torque is usually defined as the influence that tends to transform the rotational movement of an object.

This means the higher the tool’s torque, the greater the influence it can exert over the nut or bolt.

What’s more, the impact wrench you want to purchase should have torque above 200.

RPM (High Rotations Per Minute)

Since the impact tool depends on the rotations to unwind or tighten the nut or screw in its place, it should have an impressive RPM.

The motor’s rotation speed gives you an idea of the impact wrench’s performance. RPM tells you the number of times the motor is spinning each time.

Moreover, the wrench that has 3000 RPM will perform better than the 2000 RPM tool. Several cordless impact wrenches come with a variable speed trigger that allows you to change the motor speed as required.

Not to mention, impact wrenches with lower RPM delay the project completion. Therefore, you need a tool that does more rotations per minute so that your work is done quickly and you do not have to put more effort.

IPM (Impacts Per Minute)

IPM, like RPM, should be high enough because the tool requires a lot of power to push down a bolt or a screw to tighten or loosen it.

However, if a high IPM tool will break your bank, look for an impact wrench that balances IPM, RPM, and torque well.

Having a higher IPM means that there is more contact between the intended target and the tool. The greater the connection, the more the lug nuts or targeted screws will stay firmly in their position.


Impact wrenches possess a lot of power, but they are nice, compact, and are available in different weights. Go for the one that is portable and easy to carry.

A light impact gun is the best if you are working for long hours. It gives more mobility and makes it easier to operate the power tool.

Brushless vs. Brushed Motors

Brushless Dewalt Impact Wrench

Several cordless versions available have brushless motors while the others are brushed. A brushed motor has simple wiring for its performance and a switch.

Since brushed motors have simplicity in their design, they are not as effective as brushless ones. The other disadvantage is that they have a short life span.

In contrast, brushless motors have higher work efficiency and greater longevity.


If you work for an extended period with an impact wrench, the tool should be comfortable to use. It should have ergonomic handle grips to minimize work-related strain.

Drive Size

A drive size helps in the torque performance offered by an impact wrench. A 1/2-inch impact wrench is the most typical size that every tradesperson uses.

Moreover, the higher the drive size, the greater the torque will be. Therefore, when you need extreme power, opt for ⅜, ¾, and 1-inch drive size.

Reliability and Durability

Since you use an impact wrench for heavy-duty applications, it goes through much wear and tears. But if you do not want any issues for which you do not have to pay more, opt for a cordless impact wrench as it comes with a decent warranty period.

Several brands now offer impact wrenches with a two to three-year warranty. A warranty is always crucial because you can quickly get it fixed under warranty if you ever face an issue.

A question that individuals often ask is which brand is better, Dewalt or Milwaukee? We have made a little comparison here for you to understand!

Dewalt vs. Milwaukee Impact Wrench

Dewalt and Milwaukee are popular comparisons, and individuals usually ask which one is better. It often ends in a heated argument because some qualities of one brand are better than the other.

These brands aim for professionals where the tools work hard and are reliable. However, if you are looking for a stellar brand in a medium-range and have durable products, go with Dewalt. Their solid tools get the job with little fuss.

In contrast, Milwaukee does a better job. It offers more and better options for maximum impact wrench power. They are compact and offer a five years warranty period.
