CBN Tools Standard Sizes

CBN cutting tools are coated with cubic boron nitride crystals. This is the "carbide" used to manufacture carbide cutting tools. CBN is an excellent abrasive choice to cut, grind, drill, and shape steel or other ferrous metals. All A & M Instruments Quality Diamond Tools with 1/8", 1/4", and 3/8" shanks can be ordered with a CBN coating instead of diamonds. Please contact us for more information and pricing. CBN coated tools are custom made to order and require a $50 minimum order. These custom made tools are usually shipped within seven days.
