Just recently I have tried to remove the anode rod from my old water heater and failed. I was using my 3/4" breaking bar with a pipe extension, but I could not hold the tank itself. Then I tried my HF 1/2" impact gun at 120 psi air pressure and failed again. The anode rod has a 3/4" NPT thread and it's been in place for 15 years.

So I searched for the strongest 1/2" gun on the market and came up with Nitrocat 1250K. I bought it from Amazon. It came in a nice cardboard box with the Aircat bag and some paperwork. The operating instructions lists max torque at 90 psi air supply as 950 ft-lb and weight as 4.5 lb. Declaration of conformity lists max torque as 1300 ft-lb and weight as 4.3 lb.

It is very easy to check the weight since I have a precision calibrated scale. It came to 4.855 lb without any accessories or fittings attached. It is still significantly lighter than my HF gun.

It is much more difficult to check the torque rating. This is what I did. I have torqued several 1-1/8" hex cap screws to 600 ft-lb with a torque wrench (max torque on the wrench) and used Nitrocat to remove them. I have used 3/4" impact socket and a 1/2" adapter. 1250K did not hesitate to remove all the screws at 100 psi air supply. Later it removed my anode rod with no problem. It was not rusted in place, just very tight.
There are a couple of things that I don't like. The 1/2" square part of the anvil is very short at .350", it should have been a little longer. The air inlet has a 23 mm hex, which is non-standard and you have to use an adjustable wrench to torque the fitting. Also the instruction does not say a word about lubricating the hammer case. It is important you do that periodically - there is a port in the hammer case with a set screw just for that.

Despite these few drawbacks I like the gun and hope it will last for many years with a light hobby use.
For intermittent use it is not important how big your compressor or air tank is. My compressor is a little Makita with 3.3 CFM @ 90 psi and 2.2 gal tank. I use it to pump an auxiliary 11 gal tank and this is where I connect my impact gun. What is very important is the air flow to the tool. Impact guns need a lot of air flow to develop full torque. I am using 3/8" fittings on mine with a short 3/8" hose to help the flow. Do not forget to check the output valve on your tank to make sure it does not restrict the flow.

I bought this gun thinking it wasn't gonna be comparable to my snap on because of the price lol. This gun ended up being a lot stronger and a lot QUIETER than other name Brand (mac, snapon, Matco, IR) I love it and so do my ears. (I'm a big rig suspension mechanic and I put this gun through hell and back)

What I like least, is I couldn't give this a six star review.. very short learning curve on how much torque your settings stuff hat I have a Mac titanium half inch impact so I did a direct comparison on some lugs with the wheel and some other things around the shop... This mop the floor with my Mac titanium it is going (the Mac)already went into my car to go home as a Backup Tool

High torque impact, took off nuts that i had to use a 6' bar before... This thing twisted a T50 impact star bit, and shattered a non impact T50 star bit... Want torque, this beast will deliver it.

This gun is incredible. Selector switch on the back has 1 reverse mode and 3 forward modes, no button or other device to select forward or reverse like a high end competitor gun has. I used it to remove the crank bolt on a honda pilot, only touched the trigger and the bolt was broke loose with a 20 gallon air compressor and 90 pounds of air.

Seriously disappointed with this, 1250 ft lbs, no way. I went back to a big ratchet after one try. Quiet, only if you and your neighbors have ear protection on.

I use these at a auto wreckers and we get some old rusty stuck on parts and it does the job. I have some $500 Snap on guns that do have slightly more power but these are Very quiet and do the job just fine! Bang for the buck you cant loose!
