Drill Holes In Stained Glass With Diamond Drillbit

When drilling a hole in glass you'll need a diamond drill bit that fits in a regular drill motor.
With the bit in the drill, you'll want to keep the bit cool as you drill by keeping your glass submerged in water.
You'll need a plastic tray of some kind, a wooden block, water and the drill bit.
The plastic tray can vary in size, a large one will let you drill longer pieces of glass, a shorter one will let you have greater control over the drilling process.

I place a wooden block into the tray that I can rest my glass on.
I pour water over the wooden block.
Since wood floats, I push it to the bottom of the tray and pour enough water so the wood and the glass are both submerged, but no more than that because I don't want to make a mess.
I rest the edge of the drill motor on the edge of the plastic tray and begin to grind my hole using the side of the bit.
Here I'm drilling a piece of colored glass so you can see what's going on.
If you don't grind a good spot before tipping the drill up, the bit will skid around on the glass.
The place where the bit slips around will be scratched.
Once the side of the bit has ground out a start to the hole, you can begin tipping the drill to an upright position.
And you'll be able to get it up to the 90 degree angle that is normal for drilling.
Then you roll the drill around and around till the bit goes through the glass.
And here is the hole, ready to have fishing line run through it and hung on a mobile.
