SBN30
- A solid CBN grade, SBN30 is made primarily of polycrystalline cubic boron nitride (PcBN) material with no carbide backing. This allows for a greater cutting depth at increased feeds and speeds.
- Featuring the CBN grain size optimized for cast iron applications,combined with a dedicated binder, the grade provides the insert with unparalleled wear and fracture resistance.
