Can I drill a hole in toughened glass...

or will it shatter to a million pieces?

I have an old shower screen that I want to use for another purpose rather than throwing it away.

Nope....the holes have to be drilled before the toughening process.
I might be wrong though !!

You are not wrong, you cannot cut or drill it in any way {I used to, many years ago,work as a glass cutter}

I thought as much. Thanks, chaps -- you saved a lot of sweeping up there.

but there is something deeply satisfying about twanging a piece with a centre punch

once it's shattered into a million pieces, you could glue them together to make christmas decorations ...
