Drill Bit Sizes

[Seasquirt]

Can anyone tell me what size glass drill bit I'd need to drill for a 3/4 and a 1 inch bulk head?

I had ordered what i thought was for a 1 inch bulk head. 2 bits they were 25mil. It turned out to be 1 inch hole but a 1 inch bulk head won't fit in a 1 inch hole.

I did use it to succesfully drill a 20 long for a 3/8 bulk head for a gravity fed ato, si that worked our but now i need to drill a 3/4 or 1 inch bulk head hole. Thank you

And if you know where i can get one or two lol Amazon perhaps thx
