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.

Greetings

Do you think the 545 diamond wheel would work for filing the edges of an etching in concrete? I have a newly installed concrete floor, where the installer etched 1/8 " lines in the floor to simulate tile, leaving squares about 5' square. The edges of the lines are sharp to bare feet and I am looking for a filing or sanding tool to smooth out these edges. So what do you think is the best tool for this, assuming a Dremel attachment would work here. Thanks.

I'm pretty sure it would work, but it sounds like a lot of grueling hands-and-knees work. Maybe the installer has a better solution?

I'm looking at cutting glass 12" X 12" tiles.  Which attachment would I use, the 545?

For simple cutting of glass I use the standard glass-cutter's tool, which looks a bit like a pencil with a little carbide wheel on the end. I have even trimmed glass with a pair of scissors while holding it all underwater. For drilling holes or dulling the edges of glass I use my Dremel with a diamond bit.

I have a Dremel Minimite Model 750 4.8V I bought years ago and seldom use. 

I have bonded stained glass to a clear glass backing and see that I made an error and have to remove an end of a s.g. piece (to make the scene realistic), which piece is quite firmly stuck.

Does the 545 diamond wheel work with my Dremel Minimite?  Or can I simply grind away (not drilling, of course) with other attachments until I have removed what has to be removed?

Advice much appreciated!

Hi - this is Beth from Dremel Customer Service.  I know that you and I have already discussed your "dilemma", but thought I should share what the outcome was.  I had suggested that for "removing" or grinding some of the trees/scenery, it was recommended to use one of our "Silicon Carbide Grinding Stones".  (These come in various shapes/sizes.)  You took my advise, used it and it worked to grind down the glass.  You also mentioned that you used our "Diamond Wheel Points", which isn't used for "cutting glass", but certainly you can use it for carving and touch-up and finishing.  From what you told me later, your project turned out successful!  Just thought I would share this with others as well.  Glad I could be of help.  Remember, if any of you have questions or concerns, please also feel free to contact our Dremel Customer Service Department at 1-800-437-3635, Monday - Friday, 7:00 am - 6:00 pm, CST.  Any of us would be happy to assist you.

-Dremel Customer Service Team
