AirCat NitroCat 1/2" Impact Wrench #1200K
NitroCat is another name for AirCat, a company that specializes in air tools. This tool is powerful, delivering 1295 ft-lbs of loosening torque; which makes it the most powerful impact driver in this size range. Couple that with 950 blows per minute of impact from the hammer mechanism, and there isn’t much you shouldn’t be able to break loose. It’s also amazingly quiet, at only 86 decibels of sound pressure, rather low for a pneumatic impact.
This particular impact driver has a Kevlar composite case, making it probably stronger than a steel case. I don’t suppose there’s much chance of someone shooting at it, but it could probably take it and keep on working. Finally, they have the exhaust coming out the handle, so that it isn’t blowing in your face which is a nice touch.
