Kennametal Inc.’s KBH10 uncoatd polycrystalline cubic boron nitride (PcBN) hard turning inserts are designed specifically for the challenges of today’s demanding marketplace. These inserts provide extreme wear resistance needed to successfully turn hardened metals up to 65Rc, especially where very fine surface finishes are required. 

The KBH10 substrate is completely new with a PcBN composition designed for up to 20-percent higher cutting speeds while providing equivalent or in some cases far greater tool life. Because the substrate is available in different geometries and edge preparations, it’s used by manufacturers for many turning applications.

It also has a unique edge preparation. Rather than the traditional waterfall or radiused hone applied to virtually all PcBN cutting tools, Kennametal has developed a special shape that is both sharper and freer cutting than competing solutions yet still tough enough to withstand the rigors of hard turning.
