Those 1 mm discs are great. Cheap, little load on the grinder, not a lot of
material lost, not a lot of heat in the material.
Yet: all discs, particularly then 1.0mm, will shatter at times; there's a use
before date stamp on them as they expire...
So: Use a guard, think where bits might fly, think where sparks may fly (they
burn themselves into glass and tile permanently, for instance).
And *please* *wear* *eye* *protection*. A neighbor didn't, and he told me of a
chip lodged in his eyeball, how it rusted, and the medical procedure to remove
it -- used a dental drill on his eyeball.
I keep goggles in the angle grinder box now so they are handy for even the
quickest of cuts...
Thank you for the warning. I wanted to modify my old double oven so that
it would fit in my car. I used a hack saw, but did wonder about my angle
grinder. The diamond disc I use for plaster and cement/concrete has
proved very useful though it can create a lot of dust. So I was
wondering what would be suitable for steel. It had not occured to me
that the discs would have expiry dates.
Thanks for all the replies.
yet another advantage of diamond discs, they don't expire due to time & dampness.

I bought a Norton Expert slitting disc from Toolstation. Now I have it I
see why it might shatter. No marked expiry date.
