So I've got one of those tool grinders with the two heavy cup wheels. One wheel is a white aluminium oxide and the other a green silicon carbide.

You know the drill, white for HSS and green for carbide. But the white wheel is a really poor one. Very hard and seems to glaze quickly then it's mostly heat with very little effective grinding. And the green wheel is all but worn out.

So what I'm wondering is if I can get a diamond and or CBN combo that will do both HSS and carbide. What I'd like is instead of one side for HSS and the other for carbide is a coarse side for rougher shaping and a fine side for final "honing" and touching up when the edge just needs to be refreshed.

Is a coarse and fine combo that works as well for both possible?
