    Developed for hard turning, the tough CBN Grade WBH30 insert handles interrupted cuts in difficult materials. This grade, with a reliable and high-performance substrate, exhibits excellent toughness primarily because of its good distribution of mixed CBN grain sizes. In addition, it offers chemical stability derived from a TiN binder that prevents crater and flank face wear. It also provides wear resistance in hardened steels due to the 65% CBN content and higher feeds.

     

    Additional improvement in surface quality and stability can be realized with the advanced wiper geometry option. The WBH30 CBN grade inserts with and without MW wiper geometry and with a negative T-land chamfer for strength in interrupted cuts.
