    drilling steel

    Not a wood working question.
    I need a 5/8" hole in a piece of steel. I did drill a 33/64th" hole but, unfortunately, it will not work. I'm reluctant to order a $20.00 bit and pay for shipping for about ten seconds worth of drilling to open up this hole.
    I do have a lot of masonry, carbide tipped, drills. Would it be disastrous to use one of those to open up this hole? I don't care if I ruin the bit.

    What have you got to loose then?

    and the eyesight to tell the difference.

    Any plans for more than the one hole? If I dig deep enough in my "stuff" I know I have one made with a #2 morse taper on it. I just pop off my chuck and put the bit in the press. Let me know.

    Thanks, Dale. This is a drill press, not a spinny job. I'll keep that in mind though.

    I called a retired machinist friend. He said to do it. Go easy, use plenty of WD-40, watch for catches. Worked fine and I still have my eyes. Larn sumptin new now and then.

    If you take the chuck out of your drill press, you'll likely find there's a #2 Morse taper up inside there.

    Yep. Wasn't thinking that deep. Oh, well, got it done.

    I've put a super heavy duty trailer hitch and some belly bar brackets on my F-350 to hold the camper. Lot's of big holes through fairly thick steel at awkward angles.

    Things I learned:
    1) Speed kills (the drill bits)
    2) Keep the bit and hole lubed up with Cutting Fluid
    3) A drill doctor drill bit sharpener can pay for it self in drill bits on one job like that.

    I had a couple of drill bits and found that I could get about a hole and a half. taking sharpening breaks helped both me and the bits get the job done.
