Hi:
I would like to make a 1/4″ hole in some 1/8″ glass. What kind of bit can do this? Any tips?
Thanks

I have drilled holes in glass with ceramic bits. Local hardware stores should have them.
Here's my favorite for glass and ceramic:

Ken...the ones like you posted EXCEPT they're hollow work even better and can be gotten at HD for under $15 for a 3/8" bit (they have all sizes). they're hollow so you can spritz water in and in them as you dill. Goes through porcelain like butter!!Sorry I didn't add to the glass issueView Image

Excellent, Andy. I think they work in glass, too.View Image
The $3 trepanning bits from HF work well.
Tried a set (1/2 and 1" diamond drill for $3, why not ) and they actually worked pretty good, even on stained glass.

Still thinking about that DIY brain surgery?

I've found these people invaluable. I had to show them my contractors license years ago b/4 they let me have an acct. Not sure if they're still as strict...

Thanks to all for the advice.
I already have a ceramic bit (with the shovel-looking end). I will try a test hole with that and see how it goes.

I used one of those, seemed to work fine. But I only did a test. You do have to take some care I think to avoid overheating/thermally stressing the glass as you do it.
Yeh...thats it. that lil' thing popping out of the side is the piece of tile that was just drilled....thats where it comes out and also how water gets in from your spritzer bottle.You can buy a whole set up pretty cheap that has the water holder and a guide that you can attach to the wall as you drill.My tile supply I noticed carries the kit and you can find it on line for under $30 with the bit....or just buy the bit if you have no problems with it sliding on the tile. I I did it w/o the kit although next time....
I had to drill a cpl a dozen holes some real hard porcelain tile I installed. The people bought a ton of wall nick nacs....grrrrr. I freaked trying to get the holes all lined up being they had to be exact. thats when I discovered using those bits...whewwwwwwww

I'm assuming it is not tempered glass.
The old standard technique was to build a dam around the hole site with some sort of putty/clay, flood the area with an abrasive suspension, then drill with a piece of hollow tubing in a drill press.
No doubt new modern abrasives do a better job of this.
(And as someone else stated, fugidaboutit if it's tempered glass.)
My Bosch Bulldog goes right through in no time.
I'm having a bit of a problem with breakage, though.

Next time, try a rock. It's cheaper and cordless too!
