Thread: Cutting disc use by date.

Correct... And if you've ever seen them let go in anger... You'd be replacing them too....

Unless you're a crap welder, in which case they probably get consumed quickly, prior to expiry.

Hmmm, I use mine before they go out of date...

We sell cutting disks from small to huge at work and it is a check the branches do quite often to ensure we aren't selling out of date stuff. We bin (after breaking them in half) quite a few.

I cant even get the box on the shelf at work before they're all used.

I guess also a good reminder that they are rated to a edge speed. I had one customer adamantly tell me that he buys 9" wheels, wears them down and then puts them on his 5" grinder.

What's wrong with that? I've being doing it for 25 years ever since I found a 4.5" grinder with a 22mm spigot. Never even once did the disc look like being in trouble. Halve the diameter, halve the edge speed on the 9", back to normal on the 4.5"

As for old cutting discs, just gently flex them and see if they crackle and split. If they do they're junk. Otherwise just keep them in a cool dark cupboard instead of on a nail in the full sun.

If you're grinding get a full face shield, it's not just your eyes that will need protecting if the disc lets go. Dropping them also has the potential to damage them to the point of destruction, from what I read
