I have seen that sharpening lathe tools and planer blades (especially planer blades!) can be quite slow on the standard wheel. I'm considering buying the SB250 for those uses, but I notice that a local seller has a pair of D-way CBN in 80 and 180 for sale for $300 the pair. I am thinking the SB250 is more flexible, being gradable like the standard stone, and also the D-way wheels are only 1-1/2" wide.
Any advice?
