drilling glass

[leaffish75]

what type of dremel bit do i need to drill glass?

[pilot_bell777]

Can't drill temperd glass and i haven't seen a glass drill bit very large at HD or Lowes......but it takes a glass drilling bit (small ones at lowes) and takes FOREVER to drill through it without cracking it.

You would have to contact a glass dealer, and ask for a diamond glass drill bit. That is what I did. They are very exspensive though.

Ya...the diamond bits at HP only go up to like a 1/8" or something like that and then they are like 15 or 20$$$$.....can't remember.

Got the biggest one that HD sells if you wnat to borrow it.

It might be just worth forking up the money to get it drilled at a lfs store... There would be nor warrenty but at least they have drilled tanks before... would kinda suck to try it out your first time on your expensive tank and then crack it... :(

You can do it with a small diamond bit drimel but you have to go very slow and spray the cutting area constantly with water to keep it from over heating. The last one I helped drill took about twenty minutes and that was on untempered glass. It was also on a home-built 40 gallon long (through the side piece close to the bottom) for a 1 inch bulk head, so it was a pretty small hole.

If I needed to do a large display tank, I would just pay the extra money and have the manufacturer do it, especially if the holes are to be in the bottom of the tank.

Good luck.

I have a 3/4 inch diamond bit, and a 1 inch diamond bit. LMK if I can help. I have a 29 gallon that I drilled myself, also my fuge is galss and I drilled that myself. Also drilled several others as well. It realy isn't that hard, as long as you support the glass, like put a piece of wood on the opposite side of the drill point. this helps when you get close to drilling through, because the wood will keep the glass from cracking because it is so thin. If you do not supprot it, it will more than likely not leave a perfect finish. Also keep the bit lubricated at all times. This helps the diamond bit keep from getting caked up and then eventualy grabbing the glass. Which ends in a broke tank.
