The white aluminum oxide is the standard for grinding cutting tools such as chisels and plane irons. Unlike the gray wheels that come with most bench grinders, these wheels help keep your tool much cooler so your tool doesn't overheat and weaken your cutting edge. Our medium 60 grit is a good way to grind your initial bevel. Our 100 grit provides a finer edge. The very fine 150 grit is the finest grinding wheel we carry. After grinding, a few strokes on a bench stone and your tools are ready for use. This wheel is a J Grade. The 8" wheel has a 1" arbor hole with bushings for 7/8", 3/4" and 5/8" arbors. The 6" wheels have a 1" arbor hole with bushings for 7/8", 3/4", 5/8" and 1/2" arbors.
