If used carefully it's surprising what a good hole saw can do. I now only buy Starrett. Go slowly and use plenty of cutting fluid. I've cut 6" holes in 1/8" plate to mount coolant motors, and 35 mm holes in 1" plate for attachment pin holes for my digger. (and many things between these extremes)
It is quite surprising how good a finish you actually can achieve on thick plate with such a crude device.
