I agree completely... A hole saw used on a vertical mill (or even a good drill press with either a 2 axis bed, or really good marking/measuring and center punching) will produce a very good hole. (if you were
that worried about it being a 2.000" hole, it wouldn't really be cheese hole...)
As for the wear on the hole saw itself....
* Generally speaking, hole saws are made to be run slowly (bigger diameter the slower spindle speed).
* The use of
Cutting Fluid (not just oil (lubricant) or coolant) will quicken the process and also extend the life of the tooling.
