I just received a new Milwaukee Fuel 2764-22; 3/4" High Torque Impact Wrench yesterday. Have had a chance to try it out briefly. This thing is really impressive. Here is a brief video on the 2764 in action.
I saw that in the little Milwaukee catalog when I bought the 3/8 ratchet. That'll be a nice addition to my box, I don't use my 3/4 air that often to justify the purchase yet.
That is a bad *** cordless impact. I have the Milwaukee 2622-22 18v 1/2in impact and have been very happy with it. If i was a pro, I'd get this big boy for sure.
I don't have any 3/4" sockets so used a 1/2" adapter. I have the compact 3/8" (2754) Fuel Impact Wrench for smaller tasks and it's also a great tool. Really like the multiple torque modes that the Fuel impacts have.
