Are there any secrets to drilling holes in

Do you use normal power hand tools like
a drill-screwdriver and/or a drill press (if
possible with the desired bolt position)?
Do the normal rules apply, e.g. to get
a threaded hole for an M6, you first drill with
a 5.0mm drill?
And you can use chainsaw oil, right?
As Jobst Brandt stated: "I don't know many riders who believe that
drilling a hole in a frame tube is a reasonable concept."
Yes, I used to read Brandt's posts and I found him to argue false
facts just about as frequently as he did true ones.
