I typically have a white wheel and a gray wheel installed on mine. The white is for sharpening fine tools. The gray is for sharpening lawnmower blades and/or general metal shaping. I think the white is a 120 grit and the gray is 60 grit.
However, I have an assortment of other wheels too. I have a flapper wheel, a stiff bristle wheel, a couple buffing wheels.

Keep in mind thoogh that a 6” wheel will produce a very accute curve/hollow on the tool. I feel 8” wheels, or preferably bigger, is more approppriate. Also keep in mind that the typical grinder spins at 3450 rpms. Very easy to burn up a fine tool at that speed. Proceed with caution.
