Automotive mechanics are more than used to dealing with a lot of problems on a daily bases, such as:
- Rusty bolts require an incredible amount of force to get loose while most cordless impact wrenches do not have the necessary torque to deal with this issue
- Corded impact wrenches with annoying cables that get in the way when working
- Using manual socket wrenches that make the job of unscrewing bolts all day physically unbearable
- Bulky impact wrenches that don’t fit in tight areas
- Automotive mechanics need different levels of power and velocity for different jobs and most tools out there don’t offer these features
These problems are solved by cordless impact wrenches that gather specific attributes that are pretty difficult to find.
To prevent you from wasting time and money I took it upon myself to research and test various impact wrenches to arrive at the best ones available.

Frequently Asked Questions
These are some of the most frequent asked questions about the best cordless impact wrenches for automotive mechanics:
What Is The Difference Between An Air Impact Wrench And A Cordless Impact Wrench?
Well, for once, air impact wrenches are known for having a powerful torque. Moreover, they are not built with a lot of electronics which makes the tools affordable, easy to maintain, and less prone to break.
However, it’s not all roses with air impact wrenches as they are dependant on air pressure which means they need to be constantly hooked up to the air tank. This is not only annoying and inconvenient for automotive mechanics (who need maximum freedom of movement), but also increases the risk of a trip hazard.
On the other hand, cordless impact wrenches might have a bit less torque, (enough to satisfy 100% of the needs an automotive mechanic has, though). Additionally, they are dependant on batteries which increases their maintenance costs and is pretty inconvenient (especially when the battery runs off).
Nevertheless, cordless impact wrenches don’t need cables and are compact, which is perfect for automotive mechanics.
What’s The Difference Between Impact Drivers And Impact Wrenches?
For once, impact drivers are known for having a pretty good torque that lets you screw/unscrew nuts and bolts that need a high power tool. You also can use it to drill holes in hard materials and can be used by most tradesmen in most professions.
On the other hand, impact wrenches deliver a really powerful torque (much more potent than an impact driver) which is perfect for automotive mechanics. In fact, the torque an impact wrench’s motor deliver can be double than the one from an impact driver.
What Is The Main Difference Between Lithium And Nickel Cadmium (Nicad) Batteries?
NiCad batteries are affordable and robust batteries that some old cordless impact wrenches use. However, they are based on ancient technology and they hold a much shorter charge than lithium batteries.
Lithium batteries, on the other hand, are based on the latest technologies, which makes them a bit more expensive. This comes with its advantages though, as they are not only more compact and lightweight but also can hold a much longer charge than NiCad batteries which (at least for automotive mechanics) is something essential.
Which Is The Perfect Voltage For The Best Cordless Impact Wrench For Automotive Mechanics?
Well, first let me tell you that there are many voltages for cordless impact wrenches; 18V, 20V, or 36V.
Of course, as the voltage gets higher, the more power the tool consumes and the higher its torque should be.
So, what is the best voltage you ask? Well, it will depend on the intensity needed for the job. For automotive mechanics, I would recommend getting higher voltages as they will frequently stumble upon really hard nuts and bolts that will require the highest torque possible.
What Does The “Ah” Mean For Cordless Impact Wrenches?
Well, “AH” stands for Amperage Hours. In other words, this speaks about the capacity of the battery. So, when you get a tool with a higher AH, it means that you will be able to use the tool for longer as the battery will last longer.
My advice for automotive mechanics is getting cordless impact wrenches with the biggest amperage hours possible as it will be much convenient for them.
What Is The Difference Between Torque, Ipm, And Rpm?
Well, let’s go one by one so you have a better idea about these terms.
RPM stands for rotations per minute. In other words, these terms speak about the speed that a given cordless impact wrench will provide.
As for the IPM, it stands for the Impacts per minute, which is another way to measure the velocity of the tool.
Finally, the torque (which is the most important term in my opinion) stands for the force of the motor. Thus, a higher torque will give you a more powerful drive, and a higher IPM and RPM, too.
So, for those automotive mechanics confused about these terms, I would recommend you to just pay attention to the torque of each tool.
This simple number will give you the best possible idea about the power and overall usability of a given cordless impact wrench.
What Is The Difference Between Max. Torque And Nut-Busting Torque?
There’s a big confusion about these two terms and, very frequently, they get misinterpreted.
Nut-busting torque is the torque that can unlock a bolt by applying repeated shocks to it.
Max torque, on the other hand, is the maximum force the wrench’s motor can apply, both forward and reverse, on command.
Are Any Of These Tools An Overkill For Automotive Mechanics?
I don’t think so, no.
All of the tools I listed in this article have a wide range of adjustable torque to fit all the need of automotive mechanics.
I mean, it might seem that some of these tools have a high torque. But, to be honest, it’s better to be safe than sorry, and, most of them are adjustable, so that’s that.
Can You Remove Exhaust Bolts In Good Condition With Any Of The Best Cordless Impact Wrench For Automotive Mechanics?
That is why I made sure to choose cordless impact wrenches that have adjustable velocities.
This useful feature will let automotive mechanics remove bolts with the perfect amount of torque without the need of breaking any nuts or bolts.
