Cubic boron nitride (CBN) is one of the hardest materials in the world. Its hardness is slightly lower than that of diamond. For sharpening HSS tools cbn wheels are more suitable than diamond wheels. Because diamond is too hard for these metals, the grinding process may damage the tool.

— This cbn Sharpening wheel is suitable for grinding and polishing products of various materials, such as woodturning tools, high manganese steel, alloy steel, chilled cast iron, high hardness, and soft and tough materials.Can not be used for carbon steel / tungsten steel sharpening.

— Designed for use with 8-inch bench-type grinders 3600RPM (Maximum), can also be matched with other brands 8” bench grinder and you have not to worry about its use restrictions.
