    a metal hole saw will work better and faster than a drill bit, cheaper too.

    How about a hole saw?If you are enlarging an existing hole,you can clamp or tack a piece of metal on the back side of the hole you are working on for the center brill bit to go through.

    Plasma or a torch would be easy too :D

    Harbor freight saw blades and drill bits suck.It's worth your money to buy a good hole saw.

    Use lots of cutting oil and low RPM.Speed kills hole saws :D

    i could not find a metal hole saw at HF, i picked up a set of wood ones, they work ok for sheet metal, but anything thicker than 16 guage kills them fast.

    most hardware stores have them for like $7 for the holesaw (depending on size) and $8 for the pilot.

    I use Rapid Tap cutting fluid but pipe thread cutting oil works well also and is cheaper.

    Run the hole saw you have and see what happens.I use Dewalt hole saws that I pick up at Ace and I think they are between 6 or $8 but its been a while :grin:
