The EXOCARB ® MAXCBN end mills are designed exclusively for hard milling when maximum tool life, finish and precision are needed in materials up to 68 HRC. Outlasting even the best carbide substrates with PVD coatings, OSG's CBN mills extend life up to 5X, thereby eliminating start and stop marks on parts caused by tool changes.
