    Place a tape cross on the srea where you are going to drill.
    This will help the bit bite the surface.

    I tried several different bits and a handrill, I even tried my drill press but the blocks would still crack. I was so happy when I found these ready to go glass blocks with a hole allready: eBay: Pre-Drilled Lighted Glass Block Light 1.5" Inch Hole (item 290061894350 end time Jan-11-07 20:48:53 PST)

    If drilling into glass block is anything like drilling ceramic tiles, you must withdraw the drill constantly to make sure the debris comes out of the hole. Otherwise it builds up and the pressure breaks the tile/glass. You have to go a little at a time. Don't rush it.

    We've made those glass blocks with light strings for the holidays one year and this is what we used; Use a diamond bit for small holes 1/4" or smaller, and a diamond hole saw to drill 1/4" or larger holes. Also use plenty of lubrication to keep drill tip cool. Use less pressure, let the drill bit drill at its own pace. Heat and friction will damage bit otherwise, (as we leaned after many attempts and blocks!)
