Cutting small glass tiles

My husband and I are putting up a glass tile back splash in the kitchen. We are having problems with the tile cracking when we use the tile cutter the home store told us to use. So we went with our 2nd option and took the tiles back to the store marked with our cut lines (as they suggested) so they could cut it for us. However, they couldn't do it. So we purchased a Dremel and were told to use the diamond tip however we are finding actually cutting the tiles to be hard. I did some searching and found a Dremel Diamond Wheel. Will this head work for cutting small glass tiles without cracking them? Any help is appreciated!

i used the diamond blade on ceramic.  it worked great.  no problems until the blade broke.  wish i could help, but i don't know much about glass tiles.  have you tried the DIY(tv) site?  they have very good info.

You shouldn't have so much of a problem cutting glass tiles using the standard method of scoring one side, then rapping the other side to continue the break. Unless the tiles are not standard glass but tempered glass, in which case the method of cutting is another matter. Tempered glass usually scores and cuts with the method of thermal fracture, otherwise it just shatters into pebbles. If you have tempered glass tiles, you would be better off seeking out the experienced services of a professional glass cutter, for safety sake. The thermal fracture method of cutting tempered glass is not for the beginner.

I am in the same boat -- I need to cut the edges off some 1" by 1" glass tiles in my kitchen backsplash. The tiles are already installed using mortar, so I need to cut them in place. The tile backs are inaccessible, and the usual scoring/tapping glass cutting method isn't likely to work anyway because, being mortared in, they would be supported on both sides of a score line.



Doing a search on "glass cutting Dremel" turns up hits for cutoff wheels that have a diamond surface, but they don't specifically say that they'll cut glass.



The tiles are roughly 1/4" thick. I need to cut about 4 of them to accomodate an electrical outlet. Any suggestions? I suppose I could chip out the 4 tiles (which would ruin them), then try to cut some spares and mortar them in, but the task would be far simpler if I could use my Dremel tool. Is there a bit for the task?

You can try the diamond wheel and c ut it slowly with little pressure.

You also have to ensure that you do not exceed 20,000pm.  If your rpm is to high the wheel will burn as indicated by the orange glow.  Hopw that this is of some help.

Hi, this is Beth from Dremel Customer Service.  In regards to "cutting" glass... no, Dremel does not have anything that will allow you to do this.  (We do have the diamond glass bit(s) that will enable you to drill either a 1/8" or 1/4" hole in the glass), but again, we have nothing that will actually allow you to CUT it.  We also do sell our grinding/sharpening stones which work good in allowing you to grind glass, such as edges, but again, nothing to do the application of cutting.  If you have any further questions, please feel free to contact our Dremel Customer Service Dept. on our toll free phone number of 1-800-437-3638, Mon-Fri, 7:00 am - 6:00 pm, CST.  Any of us would be happy to assist you!

Thanks, Beth. Guess I'll just have to chip out the tiles and replace them with ones cut with a tile saw.

Wayner, have you tried that method? It sounds promising, but given what Beth said I'm wondering if it's worth spending the money on the rather expensive diamond wheel if it's unlikely to work well.

Sorry my cutting has been limited to porcelain tile which as you know is extremely hard.  My only glass cutting has been limited to a glass cutter for windows and picture glass.  I do not have a glass tile to experiment with but I do know that they do drill glass with diamond coated bits at low rpm and keep the bits cool with water, spray bottle or wet sponge.  The problem that you would face is that water and electricity do not mix and no one will tell you to try it.  If I can find a glass tile I will try it and post the results.  Sorry

FYI I do have the diamond wheel but have only used it on hard porcelain.

Thanks for the detailed, thoughtful replies! I really appreciate it.

Cutting tiles will work if you score well and then use the machine break tool. The cost of the machines go low to higher and the lower price machine can have poorer machining which can cause bad scoring and mis alignment of the break bar.



Cutting glass is a whole different flied. I've done some stained glass and the tools and machines are completely different. Here is a company that supplies the glass, cutting tools, cutting machines. I'm linking to the company page that has the cutting machines just to show the difference. Past that the company does have some wonderful products. "Nothing in competition with Dremel which has balked me out of project continuously. Heres a link, http://www.delphiglass.com/glass-tools/ring-saws/

I trimmed my backsplash glass tiles today and wanted to follow up here in case others need to do the same thing. To recap, I installed 1" glass tiles (1/4" thick) as a backsplash in my kitchen and needed to trim about 4 of them for an electrical outlet.



At wayner's suggestion, I used a diamond wheel at lower RPM and light pressure and ... it worked perfectly!



I also have a 662 DR bit that came with cutting oil. I used that oil on the 545 diamond wheel and set my Dremel to 10k RPM, re-oiling frequently. I started out scoring all of the glass with the idea that I'd just try to chip them at the score, but it became clear very quickly that the scores were actually pretty deep cuts and a few passes would be all that was necessary. I also used the side of the wheel to "sand down" the edges of a few more tiles to make the opening perfect for my outlet.



I understand that Dremel officially says that none of their bits are meant for cutting glass. However, at least in the case of my 1" glass mosaic tiles, the 545 diamond wheel worked very well. My tiles have beveled edges (the bevel is on the back); maybe it helped that the actual thickness I was cutting was substantially less than the full 1/4". In any case, the job was done very quickly and easily using my Dremel tool. That $15 diamond wheel saved me an awful lot of work. The alternative was chipping out those tiles, renting a wet saw or paying someone to cut a few of my spare tiles, then mortaring in the new cut tiles and re-grouting the area.



Thanks again for the suggestions -- especially you, wayner!

Hello - Dremel does make a "Diamond Wheel"; however, it's not specifically called out to cut GLASS.  It will cut, saw and carve in hard materials such as marble, concrete, brick, porcelain, ceramics, hard epoxy, soft and hard wood and granite, again, not for glass.  For the job you are doing, at this time, you probably would want to consult with someone that does stained glass and see what they are using.  I'm sorry I wasn't able to give you a better answer.  Should you have any future questions or concerns, please feel free to contact us again either by "Messaging" us, or "Emailing", "Skyping", "Chatting" or just give us a call on our toll free number of 1-800-437-3635, Monday-Friday, 8:00 am - 6:00 pm, CST, to speak to a representative in person.  Any of us would be happy to assist you.  Thank you for your question.
