Super abrasives are used for the most precision grinding. They are known for their extraordinary hardness, wheel life and exceptional performance. We offer Diamond and CBN abrasives. Diamond is the hardest cutting tool and is used when high precision is necessary. These are produced by uncontrolled forces of nature and are usually found in mines. CBN or cubic boron nitride is the second hardest cutting tool material after a diamond, and is used in grinding difficult-to-machine metals. They are more than twice as hard compared to conventional abrasives, which allows the cutting edges to stay sharp longer, with much slower wear rates.
