What size drill bit do I need to drill some 1inch hole in my glass. I also like to know 1.5 inch and 2 inch as I havent decided how big I want them yet.

1 3/4" for a schedule 40 1" bulkhead. I have the other sizes at home, but a quick internet search would yield you the info as well.

if you are wondering millimeter's...there are 25.4mm in 1 inch. if you are putting bulkheads in, there should be recommended hole sizes available from where you will purchase your bulkheads...or better yet, order your bulkheads and measure them when they get here so you know the EXACT size the hole needs to be.
