What's a die grinder?

Usually an air tool. It's a little "drill motor" that spins a small
stone mounted on a shaft, but at some terrifying speed (20k rpm). You
have to be careful using stones that are properly rated for it, and
keeping them dressed and in balance.

I can't really see how you'd shape most spindle tooling on a bench
grinder, because the wheel is just too big. I generally use either an
angle grinder with a thin disk in it, a die grinder, or just a hand
stone slip to finish up.

You can buy thin wheels about 6mm I think, and then shape the edge with
a normal wheel dressing tool.
