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

| Hello,

the side

the

drill

manufacture.

way of

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.
