Glass drill Bit.

I want to drill a hole in my refugium for a 3/4" bulk head and wondering where to get a drill bit for this.

Rona sells the diamond core bits iirc. They go for about $90 or so.

I can drill a 1-3/4" hole for you (for a 1" bulkhead). If you really needed 3/4" then you could use a bushing maybe.

That would be awsome if you could drill a hole for me delphinus, 1in wont be bad anyways.
