Drilling a hole in tempered glass.
Okay fellas who can tell me about drilling a hole in tempered glass?
I have done many on "regular" glass and my bits are good but I have all sorts of ideas as to what may happen when I run that bit into hard glass.
Any ideas will be considered, if nothing else I will tape off both sides of the glass and give it a try and let you all know how it worked out. [8D]

Keep a broom and dust pan handy, I don't think it can be done
Drilling into tempered glass requires special diamond drill bits in order to cut through the dense glass. The procedure can be long depending on the thickness of the glass, and the drill bit needs constant lubrication in order to make it through the glass. Certain glass and drill bits require different drill speeds in the drilling technique.0 -
Maybe copper tubing, valve grinding compound and some oil/grease. Good luck. Nanopulsed laser. 0 -
Diamond impreg. bit with lots of dish soapy water as lube. Whatcha making? 0 -
tubular diamond bit in a tripod mount glass drill. Make a surround of silicone caulk and use turpentine for lub/coolant. You are better off to have a glass shop do it. 0 -

Glass display case and I need power in it for a light. So a 1/4 in hole will be made .... I have extra glass so if one pops its not a real probpme.
I may go with a low pressure cup size sand blaster and use a blast abrasive called "Star Blast" I have used it before on a lot of glass just not hard.0 -
I purchased a glass drill bit awhile ago for a project I was working on. These don't work on tempered glass? 0 -

Well, it *might* work, if you're VERY lucky, but probably not, and personally, I think the chance of failure is so high, you're probably better off not trying it.
The issue is that tempered glass is sort of "pre-stressed" by the process used to make it. If you introduce any sort of crack or additional stress into the glass, the entire sheet will shatter into small pieces. Its actually quite dramatic.
Its actually so hard to drill tempered glass that typically applications that require holes in it have the holes drilled before the glass sheet is tempered!0 -
No way to run the power up the inside corners?
Think about using the clear coated lamp wire. You can run one wire up each corner if you are that tight for space.0 -
one well place rifle shot will do it.. 0 -
Any large reptile/fish type pet stores in the area? Drilling tanks is done fairly regularly, they may be able to either do it for you or recommend someone who can. 0
