OUCH!! Warning to all...

Holly Cow !, that's gotta hurt.

Doesn't say whether he was wearing heavy gloves or not, but still, and more to the point he's lucky it didn't hit his face !

The only time I've see a disc do anything like that is if I've caught it on something or bounced it while cutting.

I'm not surprised that they shattered,cutting discs are not designed to grind,....

Exactly! Cutting discs flex. I saw them shatter plenty of times when I was a steel fabricator and it only ever happened when they were misused, even with 'out of date' stock which we always had plenty of :LOL: . It even says 'cutting disc' on the discs he was using!
 
Giving this guy the benefit of the doubt, lots of people confuse cutting with grinding, it's called an angle grinder, and people often just say grinding when they mean cutting.

Would help if he showed us a closer image of the fractured discs.

Can't say he's got much of a case if he wasn't wearing correct protective clothing, and was misusing the discs.
 
Hi, I agree it could be user abuse because if they had shattered the breaks would be radial.
Those breaks look like he was grinding and was leaning too hard on the disc and they have
broken across the disc. That being said what is the expiry date about, and he is right to be
curious about the practice of restickering them.

more than likely putting too much weight on the disc.

im sure the restickering is simply that they have tested the batch and the resin that holds the disk together has not decomposed so they have restickered them, not best practice at all.


on a different grinding topic...


the bench grinder where I used to work used to have a key fob on the switch lock which was a good foot long... it read "WHAT PART OF DO NOT GRIND ALUMINIUM DO YOU NOT UNDERSTAND YOU ****ING IDIOTS" quite self explanatory really!
 
Unfortunately I've seen this happen a few times with Clarke cutting discs being used for cutting. Both with sheet and bar, only one chap got bitten but nowhere near as bad as that fella's hand but he did cop a fragment just above the bridge of the nose which missed his safety glasses. I don't know why this is happening to them, when I last saw one go it seemed to delaminate slightly first then bite into the cut and then explode as the grinder grabbed the work. As I wasn't personally using the grinder I can't say if the bloke using the grinder was twisting the grinder slightly or leaning on it too hard but as I mentioned earlier I've seen a few go now (4 or 5?), maybe there is something to it? We've stopped using them but more to do with cost than this particular issue.
 
If there is an issue with Clarke discs, then the next questions are who makes them, and are what other brands are they marketed as?
I tend to buy cheap discs - the last few batches have been "Smith & Arrow" off eBay. I only remember the wafer thin types breaking up, and that's always been my own fault.
 
I have a line of small scars and a few black spots up my right forearm from a grinding wheel that shed some bits into me.
Most have come closer to the surface as a result of the body's amazing way of ridding itself of foreign matter
over the years and been dug out during moments of boredom, but there is one large one that still
eludes my excavations, it's still a bit deep......
 
Hi, I was talking to my uncle a few years ago who was injured during the second
world war, lost the instep on his right foot and lots of debris up his leg. Shortly
before he died he was still getting bits out as they came to the surface. So have
patience you will get it eventually!!
