I need to drill some 5/16" holes through 1/2" steel plate. This is normal run of the mill plate.
The fella that I buy my steel from has quoted me $495 to drill 48 holes. He claims it is a hand drilled job.
Is this a reasonable charge? It doesn't really matter because I am going to do it myself.
I have a drill press that will probably get the job done without burning up if I take it easy. I'm looking for advice on how to drill. I'm guessing I should drill a pilot hole first then the 5/16" hole. All while using lubrication.
Am I on the right track?
