The preferred way is to use the hole_making => drilling operations.

Once you've removed the ## from the line in the opt file you can just go to Manufactuing Preferences and under the configuration tab click the 2 reset arrows and the drilling operations will show up again.
They are hidden intentionally, so that new users do not use them. If you need to maintain ole programs, then you can expose them, but you should not be using them for new work.
Please read the release notes with each new release.
