As far as a drill press goes, I guess you could do that. The diameter of the punch correlates with the diameter of the hole it is drilling, so I guess the limiting factor would be the size of the chuck on the drill you had available.
I imagine you could twist them through manually, if you were big and green, were named Bruce, and nobody liked you when you were angry. Those #10 stoppers are THICK. So, being a normal non-radiation-modified person, I grabbed my 3 pound sledge hammer and just hammered it through. There was a bit of bouncing the first couple of swings, but once the punch started digging in it stopped doing that and worked its way through nicely.
One hint: you may want to choose the punch that is one size bigger than the one you THINK you'll need. I found that in the stopper I punched through, the resulting hole was a bit smaller than intended. It'll do the trick for my needs, but just a heads-up...
