AirCat NitroCat 1/2" Impact Wrench #1200K
If you're concerned about a tool breaking or the casing becoming deformed, this NitroCat is for you. The case on this tool is made of a Kevlar composite, the same material used for a bullet-proof vest. The Kevlar provides incredible strength to the composite case, ensuring that the tool won't break even under extreme situations. It also provides 1295 ft. lbs. of maximum loosening torque, even beating out the Snap-on that I thought was the most powerful. Coupled with 950 BPM of impact power through its unique twin-clutch mechanism, there's not much that this tool won't break loose. On the tightening side, it provides 200-900 ft. lbs of torque. The Kevlar composite case also helps keep the weight down to 4.5 pounds for operator comfort.
