How to drill into glass?

[Heatheranne]

I spoke with a glass cutter recently about this same topic. They said that so long as the glass is glass and not plexiglass, it can be drilled.

did you ask him the break rate on tempered glass though. Chances with drilling tempered glass is that is going to break. if you know its tempered, I wouldn't even attemp to drill it
