where to get glass bit?

[reefnut]

i used a dremel with a number 7144 bit.it was very easy and i can make alot of other cuts then just holes.i cut a few slots and an overflow.i was very surprised at how quick it went even though the glass was from a ten gallon and very thin.

I've used these before and they cut pretty good thru glass. Just take your time with your cuts.

You can get these as well, but the $25.00 difference still makes a difference to my pockets.

Masked Reefer, have you used those economy bits to cut glass? I'm going to have about 8 small tanks to cut some holes in and do you think the ones from Lee Valley would be alright or should I stick with the Dremel diamond bit?

i think i may just get a bit off ebay... but at those prices i will only go with one size...

what size bit do i need for 1" bulkheads?

i figure if i go with that size, if i need more flow, i can just add drill a second hole.

Yes, I have used those economy bits to cut glass. I've cut 2 holes, approximately 1-1/2" diam X +/- 1/8" thick, with one bit. I probably could still cut one or two more holes from that bit. I guess it's your call on the Lee Valley or the Dremel bits. I'd ask others also to get their opinion. I'll be cutting a 65gal here shortly, maybe I'll start a thread on "Glass cutting, economy style"

I pretty sure you'll need a 1-3/4" hole for a 1" bulkhead.
