Haven't used it for long, but from what I've seen it is an extremely powerful tool for the money. A bit bulky but what can you expect for 1200 ft of torque? It is quite quiet for the power. The packaging it comes in makes you feel like the company stands behind its products 110% percent. Plus this is cheaper than other air impacts with similar or less power.

Cons: brushed metal tip scratches easy. So be sure to get a cover for it.
Bulky, so don't expect to use this in tight areas.
Heavy, but I'm sure this is to be expected.

Really hope this stands up to IR for the long term.

Been using this for 3 years. Good gun, but it absolutely does NOT have "1295ft lbs of loosening torque" like it claims. Not even close. Good daily gun, but if you need to hit something hard, get the breaker bar first.
Pro's....it QUIET!!! Lightweight. And it has lasted a long time under daily use. Would definitely buy again as long as it lasts me another 3 years.

This airgun is a great product. As advertised it has large amounts of power combined with low noise levels. I have had no problem loosening the lug nuts on my dodge pickup truck. For the cost this gun compares to any large name tool company!!

I bought this tool to remove 10 year old rusted out bolts and castle nuts on my Subaru's front end joints on the axle housing. It worked great so far and I paired them with TEKTON 4885 1/2-Inch Drive Deep Impact Socket Set (Metric) which you can pick up here on Amazon too. My Tekton impact sockets didn't end up getting destroyed like one of the other reviewer's impact sockets. I used a 30 Gallon Sanborn air compressor I picked up at Menards along with a BluBird 3/8" 50 ft. hose (also available on Amazon) which is the recommended size hose to use for the NitroCat 1200-K. I used a Husky 4 piece quick connect set I got at Home Depot to connect the 1/4" NPT fitting to the NitroCat and it worked great without any leaks on the NitroCat end. Though I do have leaks at my compressor end because I used some cheap MasterForce branded China 1/4" NPT and coupler but it leaked a lot less than having the Husky 1/4" NPT female connected to the stock Sanborn coupler (which has no markings).

The NitroCat needs 1 male 1/4" NPT fitting to connect under the handle and then that needs to be plugged into a female coupler attached to one end of the hose and the other end of the hose should have a female 1/4" NPT fitting plugged into your air compressor's coupler. Hope that help some of you who are just getting started setting up air powered tools for the first time. Took me a while to do enough research on how to get the right fittings to connect to everything and getting the right air compressor.

Be careful of the 1/4" NPT fittings/couplers as a lot of the local stuff you can buy from Home Depot, Lowes, Menards, etc... are all industrial fittings and you may unintentionally have industrial fittings hooked up to auto fittings which will cause air leaks in the quick connect/disconnect couplers. It's best to buy matching sets/brand of coupler and NPT fittings to avoid air leaks on the NitroCat. There is a difference between industrial and auto fittings and to make matters worse there are even more like Lincoln and ARO to make it even more confusing. And then if you visit Milton Industries online they will have an entire list of types of fittings from M-Style, A-Style, AA-Style, AMT Style, D-Style, G-Style, H-Style, L-Style, P-Style, T-Style, V-Style, and I'll stop there.

One last tip, when using the NitroCat to remove rusty nuts and bolts make sure you use your favorite brand of penetrating oil first (make sure to wait for 5-15 minutes so the oil can penetrate and do its job) so the stuck bolt or nut will come out easier. I used LPS KB88 as someone recommended elsewhere but you can use Kano Kroil, PB Blaster, Seafoam Deep Creep or whatever you want. Supposedly LPS KB88 is the best above Krano Kroil according to some people and LPS itself. Honestly, I don't know what is the best but the KB88 worked for me and I also tried Sea Foam Deep Creep which didn't work as well but worked better than WD-40. Sadly, I don't have the resources and time to test out Kano Kroil or PB Blaster to see which is the ultimate penetrating oil to use with the impact wrench. If I had more resources I would've purchased an Ingersoll Rand impact wrench but I would still say this is a great beginners impact wrench and you can't really go wrong with choosing it as your first wrench. No regrets, still a better buy than whatever you can get at your local big box hardware store. Of course, while searching for an impact wrench to buy I came across Harbor Freights Earthquake XT with similar pricing but with a 90-Day Risk Free Trial. Unfortunately, I do not live very close to one to try it out. Maybe consider that as an alternative if you don't want to spend more money on an Ingersoll Rand or Snap-On.

I suspect people are losing effective torque power on this impact wrench due to leaking fittings, different hose sizes, and compressor specifications. The general rule of thumb someone told me was 5 CFM per a tool @ 90 PSI per one person. My compressor is rated at 5.5 CFM @ 90 PSI which runs the NitroCat fine.

I bought this to help with my hub assembly replacement on my GMC 2500. It effortlessly removed my 36mm axle nut. It is pretty darn quiet too. I was borrowing a friends $50 husky and this tool was noticeably quieter, it is almost deceiving because you would think something so quiet couldn't possibly have this much power. I am driving it with a harbor freight compressor which can push 4-5scfm at 90 and a 3/8" ID hose.
