Drilling hole in glass aquarium-
 

Hello,
I've been trying to drill a one and one eighth inch hole in the side
of a glass aquarium but everytime I get near to the end of the hole the
glass begins to crack. I am using a Diamond glass hole saw (with a drill
guide) and applying water for lubrication according to the manufacture.
They also suggest using a drill speed of 150 rpm (which I have no way of
telling on my drill) and applying light pressure. Has anyone in this group
have had any success with drilling their own holes? Thanks! -MIKE

When they say light pressure, they mean LIGHT!!!! Just like the hobby
itself, start out slow, then taper off from there. When
cuttting\drilling glass, I don't even use all the weight of the drill
once I get close to coming through. I actually lift UP on it.

Thanks a lot for your advise, Dinky. I guess that I was applying too much
pressure. I need to be more patient even though it takes so long to drill a
hole! The tank is going to used for an external refugium and is 10
allons. -MIKE

10g's are even harder to drill consider either putting a piece of glass under the hole to
support it, or using a diamond bit for a dremel. use lots of water and take even longer.

might want to look at using a drill press at around 400rpm and a friction
lube from a hardware store

Use wood under the glass to support the pressure. At the very end the hole is
only held on in some places, which causes your crack. I would also recommend
scoring the hole from both sides and then drilling all the way thru.

Also think of it as this, you're grinding the glass down, not cutting it. It
will take ALOT of time.

I just did a couple holes in a 10 gal I'm planning to use as a
surge/sump. Worked on the first try.
I used a Dremel #7134 bit and took the whole thing into the back yard.
Right hand = Dremel, left hand = garden hose. Kept water flowing over
it throughout and I was able to put a fair bit of pressure on the
glass as I made my way around the hole.
