    To be clear- when I say I big, I mean that the drill diameter is 4x the material thickness.
    Part of the reason I have an iron worker. Punches just fine.

    And I have NEVER put one too many zeroes into my spindle speed in a rigid tapping cycle on accident.

    I've ruined more than a few drills like that but I seldom talk about it publicly.

    The previous owner of my Webb Milling machine must have done the same type of drilling but he used the automatic down feed to do it. When I got it, there were some teeth missing from one of the right angle bevel gears on the end of the worm cradle. I replaced both of them.

    The best place to drill stainless is on a drill press at high speed. JMO.

    At my wise old age I have not done that in a very long time. I hire people to do that now.
