NitroCat 1200-K 1/2-Inch Kevlar Composite Air Impact Wrench
The NitroCat 1200-K produces a power output of 1200 pound-feet of torque. Interestingly enough, the NitroCat 1200-K belongs to the same family as the AIRCAT 1150, the first product on our list. They are made by the same manufacturer but the NitroCat 1200-K is a more advanced model.

Noise Reduction Technology
The NitroCat 1200-K has a class-leading noise level of between 82-86 dBa (decibels) which falls far below the OHSA guidelines. The reduced noise generated by this tool is not only healthy but also makes it suitable to use in institutions or places of business.
Weighing at slightly below five lbs, the NitroCat 1200-K is lightweight, but is certainly not the lightest impact wrench on the market. However, the engineers fitted an ergonomic handle to this tool to counter the weight such that users can work on it comfortably for hours without getting tired.
The NitroCat 1200-K is one of the few impact wrenches on the market today designed to be both environmentally-friendly and human-friendly.
It is fitted with a tuned exhaust muffler technology that serves three purposes. First, it restricts the back flow of air to ease pressure and that allows it to generate more power.
Secondly, the muffler reduces noise emission and thirdly, the muffler dissipates the exhausted air particles away from the face to avoid ingestion by either the nose or mouth.
- Safe to use/operate
- Extremely high torque levels
- Excellent power-to-weight ratio
- Tough and durable
- Comfortable to handle
- Works silently
- No variable speed
Our final takeaway regarding the NitroCat 1200-K is that it is all about power and torque with no noise or air pollution. This NitroCat 1200-K is perhaps the most environmental-friendly impact wrench you can find at this price point and this makes it worth every penny.
Ingersoll Rand 231C Super-Duty Air Impact Wrench
The main difference between the Ingersoll Rand 231C Super-Duty and the other impact wrenches on our list is the build quality. Its body is primarily wrapped in a metal casing with some parts being plastic covered while the other impact wrenches are aluminum built.
Performance-wise, there is little difference between the five models to suggest that the Rand 231C is inferior as a result of its different build materials.
- Metal and plastic built
- Contoured handle for grip and comfort
- Pressure-feed lubrication
- Adjustable power regulator
- Twin hammer mechanism
- Maximum power: 600 pounds feet of torque
Efficient is the best word to describe the quality of performance offered by the Ingersoll Rand 231C. The motor puts out an average 600 pounds-feet of torque, but all that power is maximized to produce maximum rotational speeds of up to 8,000 rpm, which are class leading speeds.
As stated above, the Ingersoll Rand 231C features a two-piece construction of metal and plastic. Both of these materials require little maintenance. Cleaning after use and safe storage is all you need to do.
Apart from that, the Rand 231C comes fully lubricated from the factory so you can use it as soon as you unwrap it.
The best impact wrenches are easy to operate, and so the engineering team at Ingersoll Rand ensured that this is the case with the Rand 231C.
They achieved this by combining elements such as an ergonomic handle for control and comfort as well as a power regulator that lets the user adjust the power output to match the task at hand.
- Classic design
- Durable and reliable
- Comes lubricated from the factory and offers messy-free lubrication
- Comfortable to operate
- Excellent power and performance levels
- Highly affordable
- Metal construction adds weight to this tool
Despite the metal construction adding weight and reducing the power to weight ratio, the Ingersoll Rand 231C is still worth purchasing.
For starters, it is manufactured by engineers that have 25 years’ worth of experience under their belts. Secondly, it is slightly more affordable and more compact to ease any storage woes you might have.
Things to Consider Before Buying Best Air Impact Wrench
Our buying guide is structured to help you make the right choice based on your needs. It provides you with a list of considerations you need to look at before buying an impact wrench. Without further ado, here it is:
If you are a contractor, power is arguably the most critical factor to consider when picking out a new impact wrench. It is important to note that different impact wrenches provide different power outputs that are suitable for different tasks.
So going with that logic, a full-time contractor will need a high-powered impact wrench, while majority DIY homeowners can cope with a low-powered model.
While on the power matter, we’d like to bust the myth that power is directly correlated with the quality of an impact wrench. This is simply not the case. You can find high-powered wrenches of poor build quality with poor performance levels.
However, what is true is that high-powered wrenches are generally priced higher than low-powered ones but will give you an easier time loosening stubborn bolts and nuts.
When buying an impact wrench, you need to note down all the features you need beforehand to make the most informed decision. Some features to consider include, LED lights, number of speeds, power regulator, noise reduction technology, etc.
Ideally, you would want to buy an car tools made of tough materials to withstand the adverse conditions of a construction site. Here, again, homeowners can cope with less tough impact wrenches than full-time contractors.
Impact wrenches are not necessarily the lightest items in your toolbox. That said, the best impact wrenches to consider are the ones with a good power-to-weight ratio as they represent the best value for your money. You don’t want to be buying a heavy, powerless tool that will complicate your work.
