I have to drill a .6 hole 17" deep in Alum. I am thinking gun drill ? Does anyone have a type or make of drill I should look at? Also I am drilling it on a HSM with 30000K, so it does not have to much low end torque.

Is it possible to drill 1/2 way thru from each side? I do this on deep holes alot. Start with a shorter drill and drill the first few inches. Change to a longer drill and go deeper. Then a longer drill and so on. Use bright drills with polished flutes. Keep the coolant flowing and peck, peck, peck drill to clear the chips out of the hole.
