aren't hub piloted nuts metric? You using a metric socket or an inch type that could be a little sloppy fit.

33mm (brand new so no slop)

Grade 8 nuts shouldn't have a problem rounding.

My point was ... to point out, that the Dewalt gun does not have enuff poop to loosen (or tighten) a  wheel nut without having to sit there and hammer away until it finally loosens.

Probably using a gear drive or pipe to break them loose will help a lot. That washer built into the nuts on hub piloted can be a bear to break loose.

If you use a gear reduction to loosen not sure why one needs anything more than a simple ratchet or any DIYer impact.

Thats right. If he already has one. Maybe the fuel model or HF would break them loose every time, but who is going to drop coin to find out?

Milwaukee 3/4” fuel , 33mm socket , no adapters.
Put them on with the Milwaukee, checked with torque wrench all @475-500 specs. They go on and off annually with the Milwaukee, nothing else. Never let the monkey with a fresh 1” impact ruin them. A real tire shop will put them on with a 475 lb. torque stick and check them with a real torque wrench. Nothing else touches my wheel ends.

Impact wrenches of any type are hard on the fine thread dry torque lug nuts ,that is why they tell you use a few drops of oil on the hub centered nuts and washers,it's a better system than the stud pilot but can be a bear if installed dry to remove with even a 1 inch air gun

On and off annually. That is the main key to getting them loose. The ones that haven't been touched for years and ,or out in the weather, including salt or other corrosives are the ones that refuse to loosen easily.

I've used never seize on our stud piloted lug nuts - very sparingly on the threads & taper for 40 years without issue. Right or wrong it's worked for us. 10-4 0n the never removed rusty ones! We only did that once...

Interesting. If the first time is the bear and a proper torque is applied to a cleaned set of studs and lug nuts, then there shouldn't be any need for a really stout impact. If you use a torque wrench to do the final tightening then just about anything can get the nuts to settle down firmly into the rim without hammering. Good, one "need to buy" tool off this but hummm.. a new one goes on long high torque wrench. Never a free ride with a bus.

There are situations where only a 1" drive air impact like the CP 797-6 will get the nut off, or you need a geared reducer, but they take a long time to get all 10 off. When the wheel has been sitting for a decade or two, with a little rust involved, I doubt that any 3/4" battery impact is going to do the job, Milwaukee or whatever. In the case of both left and right hand threads, you need equal power in both directions. Even the 1" can run in to trouble at the recommended pressure of 90 psi, but it can handle higher pressures and get the job done (but the life is reduced). When you absolutely want to get the wheel off with no fooling around, 1".

Yep a 1 inch will either remove it or break it if you hammer long enough,fire away but I like never seize lol most people use it but won't admit to using it  ;D

Yes, a1" air, no extensions with large diameter recommended air line at 175 to 195 psi will loosen them of bust off with stud or flip bus over if it wont loosen.😊
