Drilling BIG holes in rock: SDS core bit + DCH133

Here I try drilling a 50mm hole in super-hard quartzite rock with a Renegade brand core bit/hole saw.
The drill is the DeWalt DCH133. This scenario was inspired by a viewer question, so if there's something like this you need to know, hit us up in the comments and I'll see what I can do.

I’m completely self-funded and receive no freebies or kickbacks from tool companies (lol, as if). I’m just a guy who wants to know how these tools perform, and figure you do too. You can chip in here, it'll be hugely appreciated:
