Anyone else have this happen

[Jrainman]

I use these 3'' cut off wheels every single day of my life cutting stainless pipe up to 52 inch in diameter somtimes , I can go through a box of a 100 wheels in a week , the machine you use must not have a rpm value higher them the cutting wheel rpm value ,that is the most common way the cut off wheel wil explode. wear safty glasess and safty shield over glasses , and a good set of gloves (PSE) personal safty equipment is a must .

Think of it as putting 100 MPH rated tires on a Nascar that going to drive 200 MPH in a race. what do you think will happen to that tire

That's all I have ever use is Harbor Freight grinding wheel I've had a few of them blow apart seems to me they do it when they're about half worn out . U must put safety first.
