Diamond coated hole bit

[SaltSolutions1]

Does anyone have one of these that I can borrow? I am only going to use it once and would hate to have to buy one off ebay.

Thanks

I am trying to make my 55g reef ready and it's glass.

i don't have one, but for a 55 gallon, double check and make sure it isn't tempered because most are all the way around!
