You have to use a glass drill bit. You can try a reg. one, but you risk breaking the bit, and/or the glass you're drilling through.

If you have a Dremal, I hear those work quite nicely.

Other than that, not much you can do. Hope you have more than 1 bottle on hand, because it will take a few tries without the right bit.
Nochowderforyou Reviewed by Nochowderforyou on . How to make a hole through glass? I have a glass bottle that would be a nice bong. But the only problem is I need a hole in the side of it. I dont have any type of glass cutting tools so is there any other way to make a clean hole in glass without breaking it? :confused: Rating: 5
