Electric VS Air Impact Wrench

A wrench is a versatile tool – all mechanics and handymen know that. It is used to help turn objects such as nuts, bolts, and fasteners; sometimes with pressure and torque for those tightly wounded ones.

Because of the wide range of applications where a wrench could be used, different types and styles of wrenches were also developed such as: open-end wrenches, box-end wrenches, flex-head wrenches, spanner wrenches, adjustable wrenches, air impact wrenches and electric impact wrenches.

However, for this post, we will focus on the last two types mentioned – the air impact wrench and the electric impact wrench. Both of these, however, are types of an Impact Wrench.

What is an Impact Wrench?

An impact wrench looks very similar to an electric drill. However, electric drill delivers consistent power and speeds while an impact wrench, on the other hand, produces powerful torque at a lower speed. This is the component that helps the user to fasten or remove bolts and nuts without breaking them.

Our Take on Ingersoll-Rand 231C Air Impact Wrench

Ingersoll-Rand 231C air impact wrench is a fairly powerful tool that will help you get the job done with its 600 ft/lbs max torque. Its speed of 8000RPM and 1200BPM is also fairly impressive. As such, it can be used for light to mid-range tasks but not for heady-duty ones.

More so, its build may exceed your expectation considering that it was manufactured in China. It’s remarkably solid, sturdy, and durable. It can withstand accidental drops to the ground in case it slipped your grip.

One of the downside, however, is that this tool needs be lubricated frequently in order to function efficiently. This is one aspect that most users tend to overlook but this instruction is indicated in the manual. Another point is that it produces 99dB of noise, which is loud in fact. But, such sound, although loud for a tool, is not a matter of major concern since it’s not too loud that will damage your ear. Don’t worry; it is still within the human threshold.

 

What’s the Difference Between an Electric and an Air Impact Wrench

As mentioned above, both products we presented above are impact wrenches. Primarily, they just differ in power source; as such, one is electric while the other one is air.

Let’s discuss first the electric impact wrench. It’s one of the most popular type in the recent years and from the term itself, it is powered by electricity to produce powerful torque. There are corded electric impact wrenches and there are also cordless ones.

A corded electric impact wrench is usually designed for heavy-duty tasks – to loosen or remove larger screws, bolts, and other big objects. It has an electric cable attached to its operating system and needs to be plugged in directly to a power outlet. Although more useful for bigger and more difficult tasks, a corded electric impact wrench is limited in portability. You would always need to find a power outlet or bring an extension cord with you every time to make sure that it could reach the bolt you want to remove.

A cordless impact wrench, on the other hand, is usually smaller, lighter and portable since it is powered only by a rechargeable battery. The first product we presented above, DEWALT DCF880HM2 is a great example of such. It is very handy and ideal to use in tight corners and spaces. However, the main downside is that it can’t produce as much torque as an air impact wrench can.

Moving forward, an air impact wrench is powered by an air source, usually an air compressor. As such, the number of hours and the amount of torque that your impact wrench can perform and deliver primarily depends on the supply of air from your compressor. Since you’re using two tools, technically, it’s not ideal for travelling and emergency repairs. Rather, it’s great when you’re using it in a stationary location. Also, some users claim that an air impact wrench is quite harder to set and control because it does not come with a variable speed trigger. However, with some practice and familiarity on your air impact wrench and air compressor, you would be able to control it more.

DeWalt DCF880HM2 vs Ingersoll-Rand 231C

Now that we’ve differentiated the two types of impact wrenches we have here, let’s compare the products we presented. As you may have observed already, DeWalt DCF880HM2 is a cordless electric impact wrench while the Ingersoll-Rand 231C is an air impact wrench.

When it comes to design and build, both tools are found to be of great quality – sturdy and durable. Both of them are also lightweight. However, DeWalt DCF880HM2 is significantly lighter as it weighs only 3.4lbs while Ingersoll-Rand 231C weighs 5.8lbs.

In terms of max torque, as you’d expect, the air impact wrench Ingersoll-Rand 231C produces way more powerful torque compared to that of DeWalt DCF880HM2 – 600ft/lbs compared to 150ft/lbs, respectively. Ingersoll-Rand 231C also boasts of its twin-hammer impact mechanism making it a great tool even for heavy duty tasks.

On the other hand, DeWalt DCF880HM2 boasts of features that will help you work more comfortably and efficiently. As such, it is designed with textured anti-slip grip for better hold and 3 LED work lights with 20-second delay after you release the trigger. Such features you won’t find in Ingersoll-Rand 231C.

Final Thoughts

Now that we’ve differentiated an electric (cordless) impact wrench and an air impact wrench, it’s actually hard, or even impossible, to determine which one’s better. Certainly, there are aspect(s) that will make one better than the other.

Certainly, the air impact compressor Ingersoll-Rand 231C produces more powerful torque compared to the electric (cordless) impact wrench that we have. However, such torque is also quite difficult to control for a beginner because of the lack of variable speed trigger.

The cordless electric impact wrench on the other hand, is more advantageous when it comes to portability. It’s smaller and lighter and even wonderfully designed for comfort and dark spaces – such features you won’t find with the air impact wrench.

As such, choosing between the two primarily depends on the type of tasks that you intend to do. If you are working on a heavy-duty task and more in a stationary spot, then the Ingersoll-Rand 231C is the tool to buy.

On the other hand, if the impact wrench is for light and infrequent use, then you could easily opt for the DeWalt DCF880HM2.
