Yeah, it prob'ly wouldn't be stiff enough to work right anyway.
Mostly not thinking, just picturing how square they "look".

I had a misused cutoff disk fly apart on my surface grinder, which
is too heavy to jump from the imbalance, but the fragments became
shrapnel.

Yeah, it's not as fun as a carnival ride but just as exiting. LOL

What all did the pieces stick into and how deep did they go?

Little handgrinder cuttoff discs 4", 4+1/2", 5" fly apart all the time
but they're light weight and don't penetrate, just kinda hurt and spook
the heck outta ya! LOL
