    So I was in the welding supply store today, and this warning was next to the array of grinding disks and cutoff wheels...

    I saw a similar thing happen in a woodshop. This waste of space coworker was standing there with an orbital sander held wide open, letting the pad achieve maximum velocity. The 5" PSA sheet of 120 grit slid off the pad at 20,000rpm and opened up his cheek like a machete.

    Yeeeoooooouuuch!

    I'll ad that I never buy the cheap grinding or cutting wheels. Not worth the risks. Always name brand stuff.

    I had a 7" grinding wheel explode on me with the guard in place, still got hit in the gut.....

    I'am with Dave, name brand only after that.

    Haven't had a problem since.

    While we are on this subject, remember when you start your pedestal grinder to stand off to the side....

    Name brand wheels there too....

    Ring test your pedestal and bench grinder wheels before mounting and you won't have a new one explode. Keep them dressed clean, it will also help.

    Never mount your bench wheels without the paper blotters on them either.

    Don't stop a 80 grit disk with hand either, coworker got 8 stiches in his palm.

    We have some grinders without guards. I absolutely hate them!! I need to buy a face shield. $25 is cheaper than the emotional aspect of a face injury and the medical bill.

    Always check the RPM rating of the abrasive and match that to the tool your using, at work we mark our air tools with different colored electrical tape to indicate there RPM rating to make it easier and faster to identify, and if you want to fill your pants quick be standing there when a 20 X 8 inch wheel on a surface grinder comes apart.....yikes!:shock::shock:

    14 years as a Custom Knifemaker and never used a stone wheel once. everything was done with grinding belts some moving as fast as 90 mph if one broke the sound scared the crap out of me and it just stopped moving. Never got hurt by a moving belt unless I touched it with my fingers. Old boys told me horror stories about stone wheels so I stayed away from them.
