Has anyone had experience with this process, the complete kits are pretty expensive but the bits alone aren't that bad. Would I need their collet or can I use the one I have?

No experience, I did enjoy this video when it came out. I do note a moment when he says "not that you would ever do that, wink, wink" re pressure vessel.

I was just going to post the same video
Looks to work in brass, not the prettiest result and it's obviously thicker than most of our boilers

I have watched ave video before .
I don’t think it has any practical use for us with our paper thin brass boilers .
No substitute for a proper turned insert .

Certainly a very interesting process and may have some potential applications for us, though I'm with Dennis concerning the problem of the typical thinness of our boiler shells. It may be possible to overlay a sheet of material at the hole location and thus establish a suitably thicker wall locally. This process does remind me some of using ultrasound to "weld" brass inserts into plastics which I was told could also be done in some metals in a much heavier operation with much more expensive equipment, but I'd never experienced that end of the spectrum.
Interesting to watch the video.
