Buy or borrow glass drill bit Morris Essex Passaic/ northern nj

[Kai]

Hi I might be looking to drill a tank depending on how my plans work out, I don’t really mind the size I haven’t gotten a bulkhead yet. Does anyone in the area have one that I could buy or borrow?

I have a glass drill bit you can borrow.

Kai,
I just drilled (first time) a 40b for a 2" overflow and 3/4" return.
Most overflow kits will have a glass bit in them (Glassholes, Eshopps)
Get your bulkheads for returns first and measure them. My 3/4" return actually required a 1 1/4" hole.
I bought off Amazon, specifically these, which worked very well...

With Prime there was free 1-2 day shipping.

GlassHoles is a good source for determining what size hole bit you need for a given size bulkhead. (Unfortunately the bits seem to be sized in mm and not inches.)

Note also that you shouldn't under size a bulkhead. I've seen GPH charts for bulkhead sizes. (But I can't point you at one.)

So my mom said my stand needs to under a certain size which means I need to do an all in one sump instead of connecting multiple tanks together. At least I didn't buy a drill and bulkhead, thank you for the offers and suggestions though!
