Sheet metal punches

You can't get away from using a thrust bearing for the higher torque and as you've seen the 3 part nature of the bearing doesn't lend itself very well to quick repeated use.

there's also the size of it. qmax cutters don't take much space / weight. cordless drill for making the hole is something we already have and would be used for other things. 3/8 ratchet is also something most would have in toolbox. so apart from the qmax its self, there isn't much extra weight / space required for it. if you then need to carry around another tool for just one function then unless I've got lots of holes to make, then that alone would put me off, and id just continue as i already did

I would be very interested, anything is better than a hole saw or a step drill, but not sure how you can do more, than what already exists.
As per earlier post, I too use existing punches with an impactor, works ok, cheapish and slow.
The “proper” hydraulic ones are much better apart from cost eg Greenlee/Klauke and of course the battery ones are perfect but hard to justify unless you are in the panel building trade.

But what if you were already carrying the power tool in question...?
