Must Have Features for The Best 3/8 ” Cordless Impact Wrench

These are the features I believe all ⅜ cordless impact wrenches must have to be considered the best, at least by me.

3/8″ Hog Ring Anvil

Well, the first feature to look for is, of course, a 3/8 hog ring anvil.

Using this anvil, socket replacements should be a breeze, saving the user time and ensuring the sockets are correctly installed every time.

Otherwise, you run the risk of damaging your cordless impact wrench when attempting to remove a rusted bolt with a loose socket.

Powerful Brushless Motor

For all mechanics and engineers, I suggest investing in a 3/8-inch cordless impact wrench with a solid brushless motor, which will be critical for removing stubborn rusty nuts and bolts from wheels and engines. 

I’d say the motor should output at least 100 ft/lbs as this is the standard for removing and fastening bolts.

In addition, a brushless motor guarantees optimum efficiency, saving battery life and extending the tool’s lifetime.

Variable Speed Trigger

A variable speed trigger might seem a feature that’s a bit extra, I know. 

However, this is a critical feature for workers who utilize various speeds in their cordless impact wrenches.

As a result, the best cordless impact wrenches must have variable-speed triggers, which let the user choose the tool’s RPM setting based on the job at hand and alter it quickly on the go.

Compactness

No one wants to use a bulky cordless impact wrench for many hours, especially if the tool is heavy. But, sadly, there are some occasions in which you just have to do it anyways.

Therefore, I’d advise all engineers to get a lightweight, cordless 3/8-inch impact wrench that weighs no more than 5 pounds and has a maximum length of 7 inches, as this is the maximum bulkiness of a tool of this nature should have without becoming a pain in the you-know-what.

If you don’t, you’ll be stuck with a tool that’s heavy and difficult to maneuver for long periods of time.

Quality Construction

Last but not least, we have the issue of quality.

Nowadays, this seems like a lost battle as most brands derive their manufacturing procedures overseas to save on costs, leaving quality standards behind.

However, there are still some brands that do things the right way.

This is how I recommend all workers find 3/8 cordless impact wrenches manufactured mainly in America (which is a guarantee of durability) and with top-quality materials. This is the best way to make sure your hard-earned money is well invested.


Frequently Asked Questions

Some questions frequently arise about the best 3/8 cordless impact wrenches.

This is my attempt at answering most of them to save you guys sometime in the process.

What’s a 3/8″ Cordless Impact Wrench Good For?

Well, if there’s something I could say about a 3/8 cordless impact wrench is that they’re known as tools that:

  • Have powerful motors and variable speed triggers that make it easy to take out and tighten nuts and bolts that need a lot of torque and speed.
  • Are designed with lightweight materials and ergonomic designs, at least the best ones, that are simple to handle for extended periods of time.

How Are Impact Drivers And Impact Wrenches Different?

There’re various differences between impact drivers and impact wrenches. 

Now, I’m going to talk about the most popular ones.

The first lies in the accessories you use with these instruments to make them work.

You use an impact driver to tighten and loosen screws, and you attach the impact driver bits to the tool’s chuck so that they spin as the tool is used.

In the case of an impact wrench, it’s a whole different system. 

You use a hog ring anvil with sockets attached to it, which rotates at high speed and torque to tighten and remove nuts and bolts typically found on wheels and vehicle motors.

The second difference resides in the amount of torque both of these tools offer.

The torque of an impact driver is measured in inches per pound, while the torque of an impact wrench is measured in foot-pounds.

In most cases, the torque levels of impact drivers are in the range of 1,500 to 1,600 in/lbs, or around 125 ft/lbs (this will come in handy later).

On the other hand, Cordless impact wrenches offer a far more significant amount of torque, ranging from 200 to 500 ft/lbs (and even higher levels on some of their versions).

If you’re interested in seeing a video that explores these differences more in-depth, then you can check out this man who seems to be an authority on the subject:

How Are Air Impact Wrenches and A 3/8″ Cordless Impact Wrenches Different?

The difference between these two types of impact wrenches resides in their power source.

An air impact wrench is powered by an air tank, while a cordless impact wrench relies on a battery for its power supply.

Because an external air tank powers them, air impact wrenches are low-cost because they lack complicated internal components. 

They’re also very dependable due to the lack of any internal components that might fail in the future.

However, they need air tanks and air compressors to operate, which means that workers will have to spend not only on the tool itself but also on an external air tank which can be a bit expensive for some.

You’ll also have to deal with hoses that link the air tanks to the air impact wrenches, which may sometimes be a pain.

With cordless impact wrenches, you’ll have a potent tool that doesn’t depend on wires or hoses since a battery supplies its power.

This is critical for employees who value the freedom of movement that these technologies provide.

These tools, however, come with certain caveats.

As a result of the extensive testing that goes into designing and manufacturing these devices, they are very costly.

There are also many internal components that may fail at any time and cost a significant amount of money, resulting in the need to replace the whole tool.

Battery issues are another common occurrence since they may go bad at any moment and disrupt a mechanic’s workflow.

What’s the Best Voltage for a 3/8″ Cordless Impact Wrench?

This question may be answered by pointing out a single rule.

The more torque a tool has, the greater its power since the motor has more energy to work with.

So, if you’re the kind of mechanic that needs extreme torque levels, I will say that you have to look for a ⅜ cordless impact wrench with at least 25 volts.

As for the best 3/8-inch cordless impact wrench, I recommend searching for one with at least 20 volts if you want a high level of torque that meets most of the requirements of engineers and mechanics.

That much I know from personal experience.

Can Bolts Be Removed with a Cordless Impact Wrench Without Breaking?

The answer to this question relies on two factors.

The first one is your experience as a tradesman. 

If you have years of experience removing rusty bolts, then you’ll quickly realize what level of torque and speed you must apply for a particular bolt to be removed without breaking.

The second factor relies on the level of technology the cordless impact wrench you’re using has.

Nowadays, some cordless impact wrenches come with features that automatically shut down their motors when they sense that the bolts are loose enough. 

Also, some of these tools have the so-called “bolt removal mode” which is precisely engineered to remove bolts without breaking them.

However, if you want to learn exactly how to remove a bolt without breaking them, then I’d say you should watch the following video that goes in-depth on this:

What’s The Difference Between Torque, RPM, And IPM?

Impacts per minute are denoted by the acronym IPM, whereas rotations per minute are abbreviated “RPM”. 

Both of these terms measure how quickly a particular model of a cordless impact wrench is.

The amount of power and force that a cordless impact wrench’s motor can produce is often described using the torque level, measured explicitly in ft/lbs. That’s how we get expressions like “nut-busting torque” and “maximum torque.”

It would be best if you only considered torque when assessing a tool’s power since this is the measure that will determine whether or not your cordless impact wrench can assist you in removing specific nuts and bolts.
