Well, i've been doing some shopping for glass bits/saws, and the best prices i've found were on http://www.harborfreight.com. Before I buy, i was just wondering if anyone had any other source that may be cheaper.
Ben, Adam and I had a conversation about drilling glass on the way back from the Philly zoo this past weekend and it seemed common consesus is that you get what you pay for. The cheaper bits will get you a couple holes and then you'll be looking for another.
And, like Ben said - don'y use the triangular shaped bits. Definitely go with hole saws.
The only thing I could figure is quality. I decided it would be safer to buy the more expensive ones as i KNEW the quality on those is good (per others experiences with them), whereas with the cheaper ones it is a bit iffier.
I didn't want to ruin any tanks, I guess that was the biggest determining factor for me, and i figured that with a more expensive, higher quality bit, that would be less likely.
I purchased two bits from Ameriglass and couldn't be happier with them after having drilled 8 holes.
