Are you using high speed cutting wheels on your hand grinder?
Be aware there is some real crap out there and not all of it is Chinese.
I got a batch of discs made in the EU that shatter like nothing and break up in you hand with little effort.
By fluke my brother who works some place else got his hands on the same brand.
AS fate would have it there was a big push on by one of the big companies in town to getthe chea[est thing possible.
They got it stock coded and rejected the shit after some people were hurt.
The local suplier decided to have a sale and dump them cheap.
Heads up nothing in life is cheap for a reason.....
