Drilling holes in mirror

[Alexphd1]

Anybody with experience who has drilled multiple holes in a mirror. Trying to create one of those make up mirrors.

Mirrors are just glass so you need glass drill bits like These (which I gave used on many occasions) just don't have the hammer action turned on! For bigger holes there are these which come in a variety of sizes they need a guide to hold them in place (I have a set I got from Lidl which work fine on tiles have not tried them on glass.) and they are usually run wet.

Best tip I heard was to immerse the bit of glass/mirror in a shallow tray of water.  Apaprently the water damps down the vibrations that lead to stress cracks and makes drilling glass really easy.

 

I drilled a hole in the centre of a thin (2mm) bit of glass a few years ago by immersing it in a bowl of water (sat on a weighted down block of wood) with a Dremel and a diamond bit.  Worked a treat and I was then able to screw the glass to a mandrel with a fibre washer (stopped it spinning with some superglue - easy to get off with acetone and then scrape the residue off with a Stanley knife blade), chuck it in the lathe and use the Dremel to grind it into a disc (long story, but I was repairing an old instrument that had a broken glass face and had a hole in it for the needle zero mechanism to fit through).
