33mm lugnuts no problem
I needed to do front brakes on my 2016 Peterbilt and I didn't think this 3/4 would take of the 33mm lug-nuts that were put on with an big ingersoll rand 1" air impact. Guess what, this Milwaukee 3/4 took the lugs right off with just a few seconds! I am very pleased with with the power this thing puts out. I work at a rock quarry and me and another guy have pretty much stopped using our air tools and are using all Milwaukee gear. No more trying to talk and think over a gas powered air compressor. I cant wait for the 1" impact to ship! I've already ordered mine!

A great wrench. I can't get it to allow customized settings. The coin battery (#2032 was DOA, but even with a new battery that shows 100% there is no way to customize the settings. Running Android on Note 9.

I work in an extrusion facility, everything we work on has to have outstanding torque. Ex. nuts, bolts etc.
On an average day we use 3/4" & 1" pneumatic air guns. Until NOW! This Milwaukee 3/4" impact is a beast. We tested it against every impact at our shop, the 1" pneumatic gun couldn't even take loose the nut I tighten with the Milwaukee.. Must have tool....
