Kennametal CBN Turning Inserts

KBH20™ - Developed for Your Hard Turning Application Requirements

Primary Application
KBH20 is the ideal PCBN hard turning grade in continuous to lightly interrupted applications. The structure, as well as the different edge preparations, enable tight and repeatable workpiece tolerances, excellent surface finishes, and surface integrity - even at elevated speeds. Typical applications are case-hardened components, such as gears, shafts, and other drive train components.
