My official Dremel Manual states "there are no Dremel Accessories for drilling or cutting glass". Diamond Bits are good for "etching" or drawing on glass, but not for drilling through or cutting glass.
Dremel recently introduced the Diamond Cutting Wheel (part No 545 - "Ideal for cutting, sawing, carving, sharpening and filing hard materials—including marble concrete, brick, porcelain, ceramics, epoxy and hard woods.")
The ad does not mention glass, but it does cut glass, though it would be easier & faster to cut a large glass pane with a regular glass cutter. But for some odd jobs the diamond wheel is excellent, and it grinds glass like a sanding drum sands wood. The illustration & example below should spark a few ideas for you.
Someone accidentally dropped a box of fancy glass cocktail sticks with decorative heads, breaking them in two. Reluctant to throw them away, I thought I would remove the broken stems, grind a flat base and convert them to little "show pieces" - the poor guys Swarovsky crystals :-).
After a few attempts with a fibre wheel, and odd grinding stones, I remembered the diamond wheel. It did the job in minutes, much faster than I had expected.
A small cut on the glass rods, and they just snapped off. The side of the wheel does an excellent grinding job, almost as fast as a sanding drum on hard wood. The only precaution is to have the wheel operate at right angles to your body, so none of the fine glass dust gets onto you - and protect your eyes and face.
The picture says it all. The one on right is one of the broken sticks with stem. The one in the middle has the stem cut, and bottom ground to make a base (figurine inverted so you can see ground base. And the one on left is a finished piece, and rests upright, like a show piece should.
Next time you drop a glass paperweight, or a cut glass vase or anything that looks too nice to throw away, a little imagination and the Diamond wheel could make for an interesting new project ...

You were right to use the #545 cutter works great for that. You can use the Silicon carbide grinding stones for smoothing out the cut I would use th #83142 or th #85422 to do that.
