Must Have Features for The Best 3/8 ” Air Impact Wrench
There is a list of specific features I deem essential for a 3/8″ air impact wrench to be considered “the best”.
So, I thought it’d be nice to share it with the readers to find the tool on their own if they want to.
3/8″ Hog Ring Anvil
This is an easy one, huh?
I mean, if you’re looking for the best 3/8″ air impact wrench, then you might as well start looking for one with a 3/8″ anvil, right?
Just make sure that sockets are very easy to install and replace as otherwise, it could be a massive pain in the you-know-what.
Torque
It’s easy to say: “an 3/8″ air impact wrench must have a lot of torque“.
But what do I actually mean with “a lot of torque“?
Well, I believe the best 3/8 air impact wrench must have at least 150 ft/lbs of maximum torque and at least 250 ft/lbs of breakaway torque.
I find this to be the minimum torque a tool like this must have to avoid the frustration of not being able to remove rusty nuts and bolts, which is a persistent issue for engineers and mechanics.
Speed Customization
When operating an air impact wrench, the last thing you want to deal with is not regulating its speed and adapting it to the task at hand.
This is why I believe it’s essential to find a 3/8″ air impact wrench with a variable speed trigger that will allow the user to easily modify the tool’s speed.
That way, you’ll not only save on costs, but you’ll also prevent the tool from overheating, thus, enhancing its lifespan.
Light & Compact Design
During my life as a tradesman, I’ve heard plenty of complaints about how bulky and heavy power tools are in general.
To be honest, these protests are more than justified as brands have been increasingly utilizing cheap materials to manufacture their products to save on expenses and boost profits.
The good news is that there’re still some brands (like the ones I review in my articles) that manufacture lightweight and compact air impact wrenches.
You have to look for those that weigh no more than 4 pounds and have a length of no more than 6 inches, which is the “sweet spot” for me when it comes to air impact wrenches.
Sturdy Housing
What better way of making sure that the investment you made on your 3/8 air impact wrench is successful than by getting one made of top-quality materials?
That gives me the perfect introduction for the following must-have feature: a durable housing.
If you get your next air impact wrench with a housing made of steel, composite, or even aluminum, you’ll be getting the guarantee that it won’t only be very lightweight but also sturdy enough to stand the pass of time.
Frequently Asked Questions
There are always questions flying around regarding the best 3/8″ air impact wrenches, and this is my attempt at answering most of them.
What’s the best air compressor for a 3/8 air impact wrench?
This is difficult to answer as it depends on the air needs of the air impact wrench itself.
However, what I can tell you first, is what I look for in an air compressor for my 3/8″ air impact wrenches:
- Reliability: Make sure to get an air compressor manufactured by a reputable brand as this is the best way to make sure it will last you for a long time. Otherwise you risk spending hundreds of dollars on an air compressor that won’t last you more than a year
- Portability: When using a 3/8 air impact wrench you’re usually moving around the garage. This means that you will need an air compressor that will be somewhat portable. Otherwise you’ll be stuck to one place.
- Noise levels: Most mechanics are unaware of this factor. However, I believe it’s very important when it comes time to select an air compressor, otherwise you could end up with a hearing disability
So, what is the best air compressor for a 3/8″ air impact wrench?
Let me introduce you the:
Makita MAC2400 2.5 HP Big Bore Air Compressor for Air Impact Wrenches
This air compressor has a powerful 2.5 HP 4-Pole motor that delivers 4.2 CFM at 90 PSI which is both powerful and quiet (I mean, it only makes 79dB of noise!).
It also has solid exterior protection thanks to its Roll-cage design, it can handle anything.
Lastly, its pump is oil-lubricated for cooler running temperatures, which is crucial if you want to lengthen the life of the air compressor.
What are 3/8 air impact wrenches good for?
Well, I believe two things separate 3/8″ air impact wrenches from the rest:
- First, there is the issue of power. The best 3/8 air impact wrenches output higher levels of torque (up to 700 ft/lbs in some cases) to make the process of fastening lug nuts and bolts much faster. Also, due to its high level of power, it makes removing rusty nuts much easier, which is a life-saver for most mechanics
- Then, compactness is another big advantage of these types of impact wrenches. Due to their advanced technologies, these tools are much more compact and lightweight, making them very easy to hold for more than a few hours
How are 3/8 air impact wrenches and 3/8 cordless impact wrenches different?
The air impact wrench must always be hooked to an external air compressor that “powers” the tool in operation. Unfortunately, this means that you’ll always have to deal with a hose, which can be a bit annoying when moving around the garage.
However, it also means the air impact wrench doesn’t have as many expensive internal components as a cordless impact wrench has. This not only makes air impact wrenches cheaper but also less likely to break!
On the other hand, cordless impact wrenches are powered by batteries. This allows the mechanic to work with much freedom at the expense of paying more firsthand.
Also, with cordless impact wrenches, you have the pending challenge of constantly running out of battery. Meaning you’ll have to buy an additional battery pack or be continually recharging the battery. This, of course, is an issue you won’t face with air impact wrenches as they’re hooked to external air compressors.
