I believe the guy just got a few scratches and had to change his underwear.

holy crap! and to think i only wear safety glasses when using a cutoff wheel...
Uhmmm yeah... Thats bad mmmkay.
I have had them come apart but not into my mask. Looks to me like he had the hood down while grinding, is the lense auto-darkening ?, or was he cutting blind ?
you can see the floor through the lens so I think its auto. thats nuts!
That's just a clear lens in the mask. An auto lens wouldn't be that clear. The one with it on him has the dark rectangle p'chopped in (to protect the naive I'd assume).
That's an impressive failure. Something that catastrophic is usually user error though. Twisting the grinder while cutting through stock and binding the wheel would cause that. Also, using a cutoff wheel for surface grinding can cause that sort of failure.
Appears to be a cheap press-board mask too (although I rarely use anything more than a safety goggles or a wood lathe (read flimsy) shield. Kind of makes you want to wear something protective around your neck...
if you look at each surface of the disk, it appears he was using more that just the leading edge for cutting and grinding... stupid.
using a full face shield is a good idea, keeps the sparks off the face too, but i rarely use it unless i have ALOT of grinding to do. knock on wood, never had one of these blow up on me, but have had PLENTY of the dremel reinforced disks do it. those lil bastards hurt when they hit, this i fear might have caused a potentially fatal injury. he is using a cheap shield there, im sure even a plastic shield would have done better.
hope no one got hurt.
Is now a good time to bring to your attention Harbour Freight's 10-pack of cutoff wheels for $5.99 sale? :lol:
OK, i've never had one fail, and i've burned thru a lot of them over the last year, but my dad just had one blow up on him today!!! He's a novice with a grinder, and was just etching some lines in a flat piece to make clean bends.
In the picture, I have to wonder if the guard had been removed from the grinder.
brian,
yeah thats what i was wondering too. how can the disc fly past the guard, not be deflected, etc?
steve: could you find out more on the how?
