Most of the grinder machines here have imperial (inch) shaft sizes, so we can't use those particular wheels.
I recommend starting with a 1A1 type shape, and Shars sells them about as cheap as anyone. A 180 grit is a good compromise, look for a 75 concentration. If I was setting a two-wheel grinder, I would go 150 and 320.
