Drilling Glass....??

Question

i got myself a glass/ceramic drill bit, wat do i have to know b4 i try to drill a glass bottle??
something about putting gasolie?will lighter fluid work?

Answer 1

ONLY IF YOU WANT TO BURN THE HOUSE DOWN. JUST USE PLAIN WATER FOR LUBRICANT. OR LIGHT WEIGHT OIL. MAKE A LITTL RIM LIKE WATER RESIVOIR AROUND HOLE WITH OILBASED MODELING CLAY TO HOLD WATER IN,
don't use gas man, don't know were in the world you got that idea, but no no no.

Answer 2

A normal drill bit? No. Assuming you're wearing eye protection and other protective gear, it isn't especially dangerous, but you are almost certain to crack, chip, or shatter the glass if you do it that way. You need a glass bit or a glass holesaw (for larger holes). There are diamond bits and there are carbide bits. The diamond ones are more popular, but I've heard different opinions about which kind works better. Once you have the special bit in your drill (a drill press is better), you mark the hole you want to drill, then make a little dam around it with clay or similar material. Fill that with a coolant (like a mixture of water and antifreeze, for example) and a little abrasive powder. Then, starting very slowly, you start to lower the drill onto the glass. You aren't really drilling so much as grinding out the hole. Once you have a little purchase on the glass, you can go a little faster, but not much. Take your time. Eventually, you'll have your hole if you don't rush it. Oh, and as David said above, don't even try to drill tempered glass or safety glass.

Answer 3

I suspect if I were in close proximety to you, and you were using flammables; I'd probably move away from you.

You aren't exactly DRILLING through glass, when you attempt this. Essentially your MELTING your way through it. It may seem solid, but it's molecular structure is entirely different than drilling through steel.

In truth I suspect lubrication might only slow the process, and it is GLASS after all. The diamond type bits designed to do what you want, aren't as negatively effected by glass, as they might be when drilling through a piece of tile,,,which is also essentially glass infused with aggragates.

what! no no no!- for the last time- glass needs to be "wet ground" so keep the area wet and cool- preferably with circulating water- or you can use some putty and damn up the area and pour water in then drill- be sure not to get water in drill....shocking!!
(you might be thinking of how years ago people would use kerosene as cutting oil/lubricant for the steel wheel cutter, when cutting glass- but not for drilling)
