I'll check out Lowes for the size bit I will need. Comfortable drilling plexiglass but never drilled through glass.
Do some research on the web on drilling glass. One place I lurk is reefcentral.com. It is a saltwater website that has tons of information.

One way to drill glass you build a dam around the location you want to drill. Fill it with water and then with the drill lightly press the bit onto the glass. Just let the bit drill through the hole and keep the bit and glass covered with water. Also place a towel below the hole to catch the glass as it falls. I would cover the towel with something disposable so you just throw the whole thing away.
