Looking for a drill bit to drill GLASS. Need to drill (2) 2 1/2 in holes. Any one have one I can borrow or buy that is some what local. I drilled 8 2" holes for OM 8 way and need to drill 21/2" holes for my returns.
A link would be helpfull to buy a bit if someone has one. Thanks/Tracy

Good idea with the drill bits. I went the rotozip and tile bit route.. took FOREVER, and my holes aren't snug. Have to use some silicone between the glass and threads of the bulkhead to seal it nice and tight.

Oh well.. live and learn.


Took me 1 hr for first hole... 45 minutes for second. Luckily tank wasn't tempered. I heard both ways... yes its tempered.. no its not. Finally AGA responded for oceanic. .said it was not tempered... except for the bottom which was...

Would like some pics after you get done with this drilling!
