Maybe it's all in my mind. But, when I cut ad glass it seems to snap a lot different then normal plate glass. It usually breaks off in smaller pieces.
I'm not saying that it gets fully tempered like safety glass. But, enough to change it's properties slightly.

Dave, Lick the wheel before using the Glass Cutter, it'll cut cleaner.

A long time ago I use to make lamps from 1 liter/quart pop bottles. I would drill a hole in the bottom for the wire and a small piece of tubing to mount it to a wooden block. I had moderate success with using a "glass bit" and often it would leave small chips around the hole.
An old timer that worked with glass told me to use a piece of copper tubing in the drill with a polishing compound. It worked slower, but made nice clean holes with no chipping. I don't recall the polishing compound I used, just that it was very fine powder.

I put 39 years in & retired from a plant where we made nothing but glass cutting / drilling equipment. Of course our drilling machinery used diamond drills which were just like a hole saw for wood. One drill on the bottom & one on the top would drill through the glass & meet in the middle, thus producing a slug. The grinding solution was pumice. If you don't need a perfect hole in the glass, a simple way to do it, is to glue a rubber grommet to the glass & slowly sandblast the inside of the grommet. It will work!

I have a dremel with a glass cutting tool and lubricating oil. It works very slick. To help stop the walking that was described, I put down two to three layers of masking tape. Mark the spot where I want my hole then take a little bit of the tape off where the hole will be. Its usually just enough to get the hole started. Once it's started, it doesn't walk. I've only cracked glass after I've drill a hole, never while drilling.

Might try some of the glass etching acid. I believe it is "flormetric acid" or close.. I put some in a glass bottle once, and in about 6 hours it ate the bottle in two at the top of the acid line. RD

Glass drill bits are the best way, and tape the area with masking tape, helps with vibrations.
