You can see in that saw cut that wall had standard amounts of rebar, real bank walls are formed to not allow a core drilling machine to puncture them like that.
I do not have any first hand experience in this area, so I can only go by my research and reading.
That said, this was a wall built to withstand 1940s technology, so the rebar won't be on par with today's standards.
Also, some vault technicians core drill vault walls as a matter of course, including modern examples, which tends to suggest that top of the line core drilling equipment is up to the task of tackling modern rebar. I have no doubt that the rebar makes the job a lot more difficult, but the fact is it happens routinely
