I would like to try and incorporate glass in some of my projects and was wondering what is best for drilling holes in glass? I have heard diamond drill bits are good but I not sure were to get them, like does lows have them and if so does any one know the price rang? Any help is much appreciated thanks!

You need to get bits that look like a spade on the end. Not a spade bit like you would think, but the ends of them look like a garden spade shovel.

Cheap sets are available for less than $10. Just make sure you fully support the glass and use plenty of cooling fluid. What I do is support the piece with a backer of some sort and place the glass at some sort of incline so the water I am pouring on it runs off the piece as I cut.

There is another way; I’ve seen spot-sandblasters with silicon-carbide shot through a hard steel template to make a 1/4” hole in glass. This was for making lamps out of old wine bottles, the cord passed through the hole. The bottles were filled with sand to prevent etching the inner surface.

I made some holes in the bottoms/side of a couple of large bottles once to run lamp cords through many many years ago.
I used the inexpensive glass/tile drill bits.
Slow and steady and lube/water if possible as was said and they work fine.
Follow JBfromMN’s advice and you’ll do fine, and its cheap.

if you cant find or afford a proper drill you can use a piece of copper tubing and valve grinding compound, make a dam of putty to keep it from running off. light pressure and back off occasionally use a low speed.

If it were me, I would use a glass shop to cut the glass, drill the holes, and polish the edges. I have everything I need to do the woodwork, but they’re the experts on working with glass. And, if they screw up, it’s on them. – lol
