Matthias random stuff | make cutoff disks last 10x longer (replicating Fireball Tools' experiment) @matthiasrandomstuff2221 | Uploaded October 2021 | Updated October 2024, 6 days ago.
It turns out a very long and slow cut, going over the same gouge back and forth over and over again wears down the disk 10x less than a fast cutting across cut. But it takes 3x longer to make the cut.

I suspect the reason it makes such a big difference is cutting through the metal subjects the disk to a small area with a lot of force, and a sharp edge too, whereas the shallow gouging back and forth doesn't expose the disk to any harsh edges or point forces.
