Stop in for a cup of coffee

I have a few grinding stones that chuck in my die grinder. All i have ever used them for is kbocking the ridge off brake drums,and the occasional weld grind. I have a 2” carbide wheel i use mostly for knocking welds down.

I can see doing that and I have some. I guess I was thinking I needed to know they are 22,000 rpm rated. I don't trust the pads to stay on either, will make sure I'm wearing safety glasses.
