Ingersoll-Rand 231C 1/2-Inch Super-Duty Air Impact Wrench Review

The Ingersoll-Rand 231C 1/2-Inch Super-Duty Air Impact Wrench delivers sheer power for tough jobs. This impact wrench is a must have for vehicle hobbyists and professional mechanics alike. In fact, if you enjoy working on cars and don't have this tool at your disposal, you're doing yourself a huge injustice and making your work or hobby much harder than it has to be.

In this review, I'll be going over the impact wrench's best features including its pressure feed lubrication, adjustable power regulator, construction, and impact mechanism.

I'll also discuss what previous users loved and hated about this power tool, and tips to help you make your purchase with confidence.​​

Pressure Feed Lubrication

The super-duty air impact from Ingersoll-Rand is created with pressure feed lubrication. What this means is auto mechanics and DIY car aficionados are assured with ease of use every time they pick it up. The impact wrench will easily remove tough lug nuts and even stubborn bolts without an issue, which will save everyone time and sweat in the long run.

Adjustable Power Regulator

Not all jobs are going to require the same amount of power so it's important to have an impact wrench that has adjustable power. The 231C impact wrench is capable of this and helps maintain consistent results every time you use it. With this regulator, you'll be directing variable power in one direction and full power in the other direction, which results in the freedom to set the power independently.

2-Piece Construction

Impact wrenches require lubrication to work properly. With some power tools, proper lubrication can be hard to achieve because of the way the tool is constructed. This isn't the case with Ingersoll-Rand's super-duty impact wrench. The power tool company created this model with a 2-piece construction, allowing you to apply lubrication quickly and easily. When you're done, simply put it back together and you'll be ready for the next time you need to use it.

Exclusive Impact Mechanism (Twin Power)

The exclusive impact mechanism of the 231C makes it stand out in a crowd of impact wrenches. With this Ingersoll-Rand exclusive, you can count on 1/2" drive every time you use it. The addition of this feature is what makes this power tool so desirable. While other impact wrenches may offer similar features, the impact mechanism used on this model is exclusive to Ingersoll-Rand.

With so many good ratings from past purchasers across various forums, it's safe to say most users of the Ingersoll-Rand 1/2" super duty impact wrench are huge fans of the tool and the company as well.

Many compliment the tool's ability to make basic automotive maintenance easy. However, one of the complaints about the product is that it doesn't have enough lubrication when it arrives even though it's advertised as fully lubricated. This may be because some mechanics like more lubrication than others, or it could be because the product loses some lubrication during its time on the shelves at the warehouse. To alleviate this issue, you may want to purchase an additional grease kit to use with this tool.​
