i've drilled glass and ceramic tile and stone. you need to drill
∗slowly∗. and spray repeatedly with water to keep cool and remove
residue. i've used tungsten carbide bits (can get at home depot in a
few sizes) and they do work but have a short lifetime. i got about 6
- 10 holes per bit before wearing out. most of my drilling was in
1/4" glass and granite, so i don't know what thickness you intend.
diamond bits are better, but still require water to last.
