how do you drill the holes

[idontknow]

I was wondering how to drill the holes in the tank for the overflow and one for the return?

I've had success drilling AGA 10 Gallons with a dremel tool and diamond point bits.
I set up a drip line and keep the drip constantly running accross the site to keep it cool.
Just go slow, have patience (spell?)...
BTW...just letting you know how I have been successful...I take no responsibility if it explodes on you!

Make sure it is not tempered glass you can't drill tempered glass
