I think she may mean cutting the plastic rim with a dremel. As far as i know, there aren't any glass cutting tools for 1/8" chuck die grinders. At least not in any of my "big name" tool catalogs.

Dremel 545 Diamond Wheel - Amazon.com it's made for hard materials. They don't list glass as a use, but you can find people on the web that have used it with success. It would be a long, labourous, and messy process here.

Cutting the plastic with a dremel to get at the glass would be fine though.

Oh, you meant those wheels. I know them, they are for cutting ceramic tile. Probably why i didn't think of it. I would never use it on glass. I know some people do, but like you said, it would be a mess. Ugh!!!
