    Rio Grande/Albuquerque sells diamond drill bits in packages of 5. I
    recommend the 2mm size. It is order# 349-013 $9.50 Recommended speed
    is 5000-30,000 rpm. Use a high speed precision drill press or Fordom
    flexshaft. Place glass in a pan with a sheet of rubber or green
    florist's wax. Cover the piece to be drilled with water. Apply drill
    with a light touch lifting it regularly to clear the swarf and cool the diamond.
