Can someone give me information on drilling glass.

Thanks zulu for the website. Was always wondering what the diamond core drill looked like. And was always wondering how to hold the drill bit steady while drilling. I seen that they also sell the guides that clamp and seal agains the glass and to supply the coolant. I am thinking I can get the diamond drill locally and if need be I can machine the guide myself since I am a machinist. I am thinking to just run water through the guide to cool the drill, should be no reason to need oil. And also I will check into the dremel idea further, I will talk to the tool supplier and they should be able to give further comments.
