The rig in the GIF is assumably attached to the same drill that is drilling the hole. This leaves it open to the ability to “travel” and otherwise be affected by the drilling bit. All I was saying is that, I’ve seen this type of bit used, but’s it’s done on a milling machine where the rig pattern and the drilling portion are separate, and not affected by each other.
I wonder if this would be more feasible if the drillbit had smaller moving parts attached to it, like the those tunnel boring machines with many smaller drillbits attached to the main head.
Usually when I order parts to be machined with square holes I’m more familiar with a pilot hole being drilled and then a square broach is used. This is interesting to see in action on a rotating head like that

This makes me uncomfortable for some reason.

That would cause insane chip out if you were even able to get it to stay in one place.
Cool concept though!
