Joseph,

    I doubt that a carbide tip will drill ceramic!  You are talking
    about a material that is or approaches a 7 in hardness.  The only
    way you can drill it is to use a diamond drill.  If you  only plan
    on one or two holes, check out Harbor Freight or even your local
    flea market.  Many tools vendors sell the diamond plated bits that
    are just fine for a hole or two. 

    Be sure to keep the drilling site wet, preferably under water, to
    keep it 

    cool and clean. 

    Cheers from Don at The Charles Belle Studio in SOFL where simple
    elegance IS fine jewelry! dcdietz AT  comcast.net
