About $9/disc on Amazon, not cheap. Might be worth having one around for grinding tempered metal.

Leave it to 3M, they are always coming up with outstanding products.
However, this one is kind of abrasive!

I’d like to know the physics behind not heating the bolt when grinding off the metal. Removing the metal quickly isn’t a way to keep it cool, in my experience. I’ll wait for more evidence.

Isn’t the heat just friction between cutting material and metal? So the faster it cuts, the less contact time between abrasive and steel. Seems like that would reduce heat.
