well i tried the same thing, i started off slow and started seeing a little progress after a little bit, but stupidly i tried the push hard to hurry the process up and the glass broke. So just take your time and eventually you should have clean hole.
headydankness Reviewed by headydankness on . Drilling very thin glass I found a Volumetric Flask. It's glass and its about 1.5 feet tall. The glass is very thin and Im wondering if i use a diamond bit drill and go slowly as well as wetting the glass with water will it crack? Rating: 5
