I am a glass artist. I can drill glass. Using a water bath setup I tried to drill a hole through a sheet of glass (about 1.5mm).

I am very happy with the holes I can drill in flat glass. But cooling is very important, I damaged a bit when glass dust accumulated and water couldn't get to the bit. But as long as there was plenty of water around the drill, it cut very clean and reproducible holes. And I cut many holes in a tight web, after blowing through the first piece and learning my lesson I had no trouble drilling more holes.
