Maybe slightly off topic but I plan to use them on my Mercedes. And I have searched but found minimal info.

Planning on finally buying a 1/2 air impact wrench - and looking for info on brands. The safe path seems to be Ingersoll Rand such as the 231G or 231HA,

Anyone know anything about other brands such as Aircat which have very high torque specs (which seems to be based in WA state but who knows where they are made, claim to fame seems to be noise reduction which is not really a big deal with home use)

Thanks
