More like an order of magnitude more rigid.
It isn’t as simple as swapping a 19mm diameter for a 50mm one, but even that
indicates more than doubling

Speaking of mill alignment. It's been years since I did this and then I didn't
have the more accurate gauge. I did get an old brake disk surface ground flat.
That makes spinning the indicator around while tweaking so much nicer. The

Set screw tool holder accuracy is down to how precisely the holders are made. A
lightly oiled tool should pop when pulled out of the holder. Where this type of
holder doesn't do as well as a collet is in heavy production work. They need to
be monitored for getting bellmouthed. A precision rod
The set screw isn't angled, that flat ground into the side of the tool shank is
angled.
