Richard;

    I'm sure you'll get many replies to this prior to mine (through the
    daily digest). 

    I have never had any problems using a drill bit (as small as 0.5 mm
    dia) to drill holes in metal.Using a bur at high speeds will burn it
    out very quickly, probably before you "drill" the first hole. 

    Use a drill bit with firm but light pressure, not too fast, and well
    lubricated with cutting oil. You may break a few drills at the
    beginning until you "get the feel", but you'll know when the speed
    and pressure is right by the tell-tale spiral cuttings you produce. 

    If the bit is too small to fit into the handpiece, get an adapter
    (almost like a pin vice) to fit your handpiece.
