invision Reviewed by invision on . Can you drill a hole in glass ? what is needed ? what type of drill bit ? I want to make my own bong , and I have a really nice piece of glassware i want to use , and then add my own bowl etc. Can this be done ? I practice drilled a Corona Beer bottle and it shattered just as i drilled through . :( Rating: 5
