    You should drill with High Speed steel bits and plenty, plenty of
    lubrication.  Slow speeds are best. Heat travels very slowly in Ti.
    The bit can heat up to temperatures that can both untemper it and/or
    cause the chip to weld to the bit and break it. Cool and slow is the
    game. 

    In most cases ordenary files work fine. Some alloys of Ti, say Grade
    #5(6/4) are very hard. They can cause rapid wear. Diamond is good,
    but in general files are cheap and replacement is easy. Bill
