Guys pick up this grinder with the purpose of sharping HSS. It was suggested to go with the white aluminum oxide type K wheels but I can't find them that will fit this grinder. My plan to to grind close to what I need on bench grinder then put finishing touches using this grinder with couple different grits. I also read a little about CBN wheels but is that for HSS or carbide? Any suggestions,links pics of your setup be very helpful and suggestions.
