=> the spinner backplate. These things grip like crazy!

The only potential problem I see with this idea is that [some types of]
cutoff disks are a bit brittle and might want to crack under stress. An
equally simple solution is a couple of disks of 180 sandpaper, back to
back.

The tiny hole in the cutoff disk has to be enlarged, and it can be
difficult to drill it out without breaking some types of disks.

Good idea, just the same.
