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.Â* 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.

"Grinding Wheel ! ! ! ! " was always a warning shouted in a machine
shop when a grinding wheel (which rotates at every high speed) broke
loose from its spindle and rolled menacingly down the shop.
