Here are some previous "tips" that I had saved.
Glass: I do stained glass, but I have a couple of very interesting bottles and would like to cut the tops off them. I've contacted Customer Service and they don't suggest the diamond cutoff as the heat will dull the blades, and I can't use water to cool the blade as I do with the diamond grinder for the stained glass. ANSWER: The Moto-Tool or Spiral-Saw will not "cut" glass like wood. However, with a green silicon carbide stone or diamond-sanding bit, you could smooth/grind/shape the edges and engrave the surface. Note: replacement window/door glass usually has to be tempered. It is typically against code to use ordinary glass (like single strength). Another: I want to know if it is possible to grind the edges of glass that has been freshly cut to make it a smooth edge. By using the silicon carbide bits? I understand that most of the time you need a "glass grinder" because of the wetness needed, is there a way to do it with a Dremel tool? I did this once, about 10 years ago (had to replace the colored glass in a leaded window). I put the glass on a piece of window putty to elevate it and placed this in a pan of kerosene. Did the grinding, in a drill press, with an aluminum oxide bit, at the lowest speed. Messy but did the job. Another from a Demonstrator: Yes, it is not written as the recommended method in some manuals, but the Dremel Tool on high speed with the Tile Cutting Kit #566 will work on Mason Jars. The Carbide Cutting Bit will be used to drill the pilot hole and open the hole up larger. DO NOT allow the blade to get RED HOT ... it is now DULL. It also works great on carving the Red Clay Pots, Glazed Pottery, etc.
Another: I have used the tungsten carbide bits 9903 or 9910 or diamond coated bits to make nice 1/8" holes in the bottom of mason jars. You must go slowly to avoid over-heating. Drill a little and wait a couple of seconds and then drill a little more. Any time that I have tried to do the job with a diamond point, I have ruined the bit.
Another: For glass drilling the wet sponge placed under the plate or whatever the glass object shape is helps to make the drilling go faster and less breakage to the glass.

| I create incense burners and other items out of wine and old liqueur bottles. For an incense burner I need to add air holes in the bottles so there is free flowing air as the bottle fills with incense smoke. No airflow, means the incense stick will go out. For this job I use the 7134, or the 7144 pointed diamond tips. I first submerge the bottle into a bucket, filling the bottle with water. I add my tip to my Dremel two speed, also using the flex shaft. It's much easier to manipulate the flex shaft as the drill gets a bit heavy after awhile. Holding the bottle by the neck and just bringing the bottle to the surface almost to where you will be drilling. Using the low speed I lay the tip on the glass, you can do this while it's in the water, it won't hurt the flex shaft at all. Slightly angle the tip until it creates a slight groove. I then can bring the tip up, or tilt the tip up. While creating the hole I go in a slow circular motion as to grind the bottle. It only takes a few minutes to get the tip through the bottle. I can then switch out tip sizes or just continue to go around the hole and make it the size I need. I've been creating the bottles for several yrs now and this method seems to work the best, it not only keeps the tip cool but also if the bottle does break, all the glass fall to the bottom instead of flying at you. The water helps keep a barrier between you and the broken glass. Hope this helps some Charlotte

I was wondering if it would be good to wear a "dust mask"? I heard that the glass dust would not be good to get into the lungs. Thanks.

Hi Tabbycat
Yes, a dust mask should be worn and don't forget to protect your eyes too!
