On one hand, the machinability makes high speed machining achievable with little harm to a drill or tap. Hand drilling steel plate The Hobby-MachinistI would have tackled this with a stout hand drill 5 years ago (pilot holes are a must as stated previously). Today I would use a mag drill. I did this a while back by putting a steel plate (1/4" is all I had on hand) under the machine (a jointer) and fixing my mag base to the plate (thicker is better) and drilling through the iron cast into the steel a bit (saved my floor).
