This was a pretty new disc. I didn't realize it was falling apart till the grinder bucked in my hand. It could have been a lot worse.

Good post Mick, glad you didn't get hurt. And just a reminder to the new guys that this is one tool that you must wear eye protection 100% on the time.
I always wanted to try a diamond disk on my grinder, but every time I reach for one at the store, I see the scars on my hands and fingers and remember the ones on my knees and am reminded of why I have never bought one. :)
Mick, Just dont hit your hand with one of these. it really hurts

My helper has an artificial lens and lost most of his vision in an eye due to a disintegrating disc (on an air powered grinder), I have had disc chunks go through Carharts/gloves etc. It is super dangerous, I only use electric now and try to never use thin cutting discs, I have not seen any difference in brands except that the Forney's seem to not disintegrate into chunks( but they wear out really fast).Full face mask is recommended.
What brand disc was it?
Dont leave them outside either for a extended period. I see this happening every spring with chopsaws.
Great advice man!Quote:

Yep. I've had them just shatter on me, scared me the first time it happened.Quote:

I only have one good eye (can't even read highway signs with it) so I have to be super cautious when I'm working, if I loose my good one, I'm out of luck. I was wearing prescription safety glasses at the time, but the rest of my face was exposed at the time. After that, I went and bought a face mask at Harbor Freight to wear over my glasses for extra protection. I guess I would just say always stop every once in a while to check. It may be the two second check that could save your vision.
I bought this face mask:

I had one shatter on me as well, One piece went through my glove and into my thumb cuticle, the other two pieces shot off and went into my leg, just above the knee. Still have the scars as a reminder every day.
Knock on wood. I use cutting discs almost everyday at work and have never had a problem. They do get worn and start to crumble apart like the one in the picture but I've never seen one explode. The reason they wear out like that is your putting too much pressure on it. When you use a cutting wheel you let it sit softly on the metal surface that your cutting. Let the wheel cut through and progress on its own.
Also when trying to use a cutting wheel in a limited access area, if you hit a corner or something it will chip and ruin the wheel like the one in the picture.
What size of disc have... want to see some original pictures of this ...
after working as a fabricator for 9+ years i've learned a couple things.
1. position your body so that it is out of the plane of the sparks. (old jeans are netorious for catching fire.) and when it binds and catches it will kick out.
2. close fitting safety glasses or goggles, and a faceshield. always 2 layers of eye protection. faceshields have different impact rating requirements than safety glasses,and are designed to deflect mutiple small particles, where safety glasses are designed to protect against 1 impact.
3. eye protection is a consumable and should be thrown away after it has done it's job.
4. moisture/ humidity destroys grinding discs. they get hot and the water rapidly expands into steam causing them to explode.
there are tons of safety videos on youtube Angle Grinders (2 of 4) - Graphic Content! - YouTube
Thanks for suggesting us for the better way to use the grinder blade to avoid the accidents.... thanks
