    The smaller the hole the faster the drill should spin, but this
    isn't always doesn't work other than in theory. You didn't give the
    hole dia or drill size. So this is a general description. 

    First the metal being drilled should have every location that will
    be drilled center punched with a well defined mark. 

    Your drills should be sharp I'm refering to twist drills, you didn't
    mention what style of drill you are using. 

    If the hole dia. is under 1/16" and the number of holes is not large
    use a spin drill that you twist with the fingers. and some form of
    lubrication. light oil or bees wax, or commercial cutting fuild if
    you have it. 

    If you are using the drill press the item should be securely clamp
    or held down to the surface of the drill table so it doesn't wobble
    wiggle or move. Or worst case get caught by the bit when it starts
    to breaks thru the metal and ripped from the hand holding it and
    start spinning around. Very bad cuts, broken fingers ect can result. 

    Have you thought about a punch and die set like this; 

    http://da.harborfreight.com 

    Items: 91510-0VGA, 44060-7VGA 

    the deep throat punch set has a bench mount that you can buy. 

    If the hole is a large dia size you might want to try a punch and
    die set or just a hand punch with a untemepered masonite board as
    the surface you cut thru the metal too. It will keep the punch
    sharp. 

    harbor freight has any number of punches and sets they have three
    pages of punches. 

    The last thing with using a drill press and small dia drills is use
    a gentle downward pressure on the quill wheel when drilling the
    metal also lube, lube, and wear your saftey glasses. 

    all the usual disclaimers apply a satisfied customer 

glen, been there and done that and broke more drills than I woulkd want 
to count!
