I have always read and been told that a slow speed grinder was better for sharpening lathe tools, that the high speed grinder would cause too much heat. The instruction manual for the Oneway Wolverine system says to use a high speed grinder. They recommend an 8 inch grinder @ 3450 rpm. They say surface speed should be between 6000 and 8000 fps. 8"@3450rpm=7225fpd. 8"@1725=3612fps
