9" angle grinder with a diamond blade that is stuck on.

Would you trust a disk that has been clamped in a vice?

Yes, always tighten them properly by hand first. If you allow the rotation to do it for you, the nut "slams" tight and will show a distinct tendency to jam.

This isn't a huge problem with =A350 mangle grinders and consumable blades (you can afford to be destructive, if you have to). On $500+ cabinet saws with =A350 blades and more inertia involved, it's a real problem.

If you're changing a diamond one chances are it's because it's worn out.

Half the cost of the stolen one it replaced, though.

I think the lock was inadvertently operated while the m/c was in use. Probably trying to get somewhere not really accessible.

Denting the thumb tip usually works.
