I don't know, from using these kinds of tools all my life non of the half inch is reaching 600ft-lb real torque in my estimation.
Case in point i have an old US Made IR 231, it is heavy and was only rated IIRC at 450 working torque. Real world it holds it own against almost anything.
The AirCat is definitely stronger but not 700+ pounds stronger.
Maybe someone can post how they get these numbers, they just don't seem to translate into real world performance.
As you can see in the video 446 was all a 900ft-lb rated gun could pull.
IR says this.

Since torque capacity is effected by many variables like bolt type and size, thread conditions, air pressure, CFM, etc., a comparison test can be difficult for an end user to replicate. And since there’s currently no industry wide standard for testing or publishing torque ratings it difficult to compare published torque ratings across manufacturers.
I can only compare guns i use on my compressor, same hose, same connector, same psi and cfm.
On this set up the AirCat is stronger than the Ti and the 231. The old 231 is so close to the Ti its hard to tell the difference, note the Ti is old but so is the 231, the 231 has not lost much if any power over the years the Ti has and considerably.
To be fair an inexpensive rebuild kit and buttons will get the Ti running like a champ again but that says a lot for the 231 that has seen the same amount of use and is rock solid (you cannot buy this 231 anymore, the new ones are Chinese).
I use an inline oiler on all air tools so neither has gone short on lube.
For air ratchets and other air tools i use IR, they are great tools! But..
Given the power of the AirCat, the price and the warranty i have to give the nod to it.
