Yesterday I was asked about "how could you" drill a 1/16 hole thru 2 1/2 inches of steel [astm36]. Accuracy on diameter is +- alot, alignment top and bottom is say 1/32". Of course you can drill both sides and then run a bigger drill thru the hole (surface finish does matter a little) to ream it out.
But I was wandering if a edm drill could do it in one shot, and how long would it take?
