When drilling steel that is hard I tend to use Copperhead annular cutters in my mag drill with coolant. Copperhead annular cutters are carbide tipped so no issue making holes with them. You have to use them in a mag drill because of the Weldon shank.Can the steel company drill the holes? That hardened stuff is tough unless you have a good drill press or mag drill.
