Using an air cut-off tool

Air cut-off tools generally aren’t that expensive, but you could spend the same amount of money on two different models and get a radically different experience with each. One may last forever and cut materials far harder than it ought to be able to, while the other may fall apart within a few uses.

It can be hard to shop online for these tools, as you have no real way of knowing if you’re getting a good deal from reading a product description and looking at a few pictures. We want you to be well-informed when you buy, which is why we’ve created this list of reviews of some of the best air cut-off tools of 2019. This list should help you find a model that will work well will fit in your budget, and will also give you many years of low-frustration service.

3 Best Air Cut Off Tools 2019 – Our Reviews:

1. Astro 209 ONYX Air Cut-Off Tool – Top Pick

Astro 209 ONYX

The Astro 209 ONYX is our choice for best air cut off tool. It comes with an in-line design which keeps the entire device compact and easy to use. It comes with lock-out throttle protection, which makes it hard to accidentally start the device, which is a great safety feature, and also means you won’t accidentally cut where you don’t want to. It comes with an adjustable guard, which is great for channeling sparks away from you.

It also comes with variable speed control, which means you can set the speed to the project at hand. Customizing the speed to the material you’re currently working on means that you get a better cut, with fewer jagged edges, and fewer false starts where you can’t efficiently cut through the material. However, this device has a high cfm, so despite its small size, you need a compressor with a big tank and a big output as well to get a good amount of power out of this model. If you already have a good compressor, you’re set. Given all the upside to this model, it would be hard to place it any lower than first on our list.

Pros
  • In-line design
  • Lock-out throttle protection
  • Adjustable guard
  • Variable speed control
Cons
  • Needs a good compressor

2. DEWALT DWMT70784 Air Cut-Off Tool – Best for the Money

DEWALT DWMT70784

The DEWALT DWMT70784 is easily best for the money on our list. It comes with a lightweight aluminum body, which provides plenty of strength but also keeps the weight down, making a strong, but lightweight device. The touch control trigger is easy to use but also features a safety, so that you won’t set this model off accidentally. It also comes with a cushion grip which makes it more comfortable to use than competing models. Those two features together make a big difference in how much you’ll like using the tool relative to its competition.

This model is also great for use with smaller compressors. It has a lower cfm, so while you’ll always get the best high-end performance from bigger compressors, you can still get good performance even when the pressure isn’t as high. The one problem with this model is that it’s a bit bulky, which makes precision work a bit harder, and will wear your hand out more quickly if you’re planning to use it for hours at a time. However, the price on this model is fantastic, and if you’re looking to get a deal on an efficient model, this is the model for you.

Pros
  • Aluminum body
  • Touch control trigger
  • Good for smaller compressors
  • Cushion grip
Cons
  • Bulky

3. Ingersoll Rand 326G 3-Inch Air Cut Off Tool

Ingersoll Rand 326G 3-Inch

The Ingersoll Rand 326G 3-inch is an interesting air cut-off tool, given it a mixed bag of strengths and weaknesses. It has one of the best shields on the market. It’s larger than most shields and is also made from steel for superior protection from flying debris. It also has a front exhaust, which blows the hot air away from you, instead of the rear exhaust common on other models. That makes it more comfortable to use. You can also get it at a good price, which is always a plus.

However, the giant shield makes it quite bulky and bad for cuts that you need to make in tight spaces. It also has an annoying safety. There’s no way you’re going to turn this model on by accident, but that also means that it’s hard to turn on when you want it on. That means you lose a bit of time every time you use this tool, but also that it’s going to be more frustrating than other models in that regard. However, if you don’t mind how bulky it is and want an air cut-off tool that is very safe to use, this is the model for you.

Pros
  • Great shield
  • Front exhaust
  • Good price
Cons
  • Bulky
  • Annoying safety

Conclusion

The Astro 209 ONYX is our favorite model due to its in-line design, variable speed control, and adjustable guard, which makes it easy to make cuts at any angle. The DEWALT DWMT70784 is our choice for best for the money, given its low price, lightweight and strong aluminum body, and how well it works with undersized compressors. However, it misses out on first due to its bulky case, which makes it hard to use for long stretches. The Ingersoll Rand 326G 3-inch has a great shield and expels hot exhaust out the front, but is also bulky and has an annoying safety, dropping it to third on our list. All of these air cut-off tools are worth checking out, and since they have different features and come at different price points, it now comes down to you to find the model that’s right for you.

We hope that our reviews have helped you understand what makes for a good air cut-off tool. Armed with this information, you should be able to find a model at a great price that you’ll also love using.
