A diamond drill bit will work best. Diamonds are a harder substance than glass, so they are perfect for drilling hard substances.

A diamond drill bit is recommended. However, if you don't have one you can tape the inside and outside of the glass you will be drilling with packaging tape, masking tape, or painter’s tape, right over the spot you plan to drill. This will stop the glass from splintering, and it will hold the drill bit in place.

To drill a small hole in glass, I recommend using the diamond bit rather than a titanium one.

Question

I want to drill a hole in glass, but I'm not quite sure what type of glass it is. How do I tell if it is tempered glass or safety glass?

To tell the difference between tempered glass and safety glass, check the corners. Tempered glass will have a marking on one of the corners.

The easiest way is to put a piece of tape over the area you're going to drill, use a diamond drill bit, and go really slowly.
