A local place has these on sale; I could easily mount it on the grinder.

This for small bits - 7x10 lathe.


diamond is the choice for sharpening carbide. If you're talking about
brazed bits, keep in mind that the soft steel underneath EATS diamond. I
have two wheels on my baldor, the green wheel is set to 8 degrees for
ruffing and then the diamond wheel is set to 5 degrees for finish sharpen of
the carbide.
