I agree, only use the grinders with the paddle switches!!!!! I know from experience!!! and only cut in the direction of the rotation,same goes for wire wheeling,the wheels will grab and break if trying to go the wrong way....I only use harbor freight wheels,both cutoff and grinding wheels and haven't had any problems,just have to use a good wheel, not damaged at all....

I've used those disk to cut a ton of steel for many years.

The root cause is plunge cutting!

So either don't plunge cut or if you do be sure to hold the grinder square to the cut. If it goes wonky toss the disk and get a new one.
