Select a PCBN Grade
Start with workpiece material and cutting continuity, then balance wear resistance, toughness and surface-finish requirements.
| Grade | Approx. CBN Content | Recommended Condition | Typical Application |
|---|---|---|---|
| OBN45 | 45% | Continuous to moderately interrupted | Finish hard turning, high-speed turning and fine surface finish |
| OBC50 | 50% | Continuous to lightly interrupted | General hard machining and cold-work tool steels |
| O2C50 | 50% | Continuous to lightly interrupted | High-speed hard machining with abrasion resistance |
| OBX60 | Approx. 65% | Moderate to heavy interrupted turning | Hardened steel applications requiring higher toughness |
| OBW85 | 85% | Heavy interruption and abrasive materials | Grey-iron fine boring, valve seats and abrasive workpieces |
| OMB90 | 90% | High wear resistance | Grey/hard cast iron and hardened-steel turning or milling |
CBN Inserts by Machining Application
Match the PCBN grade and edge design to the workpiece material and level of interruption.
CBN Inserts for Hard Turning
For hardened steel, bearing steel, case-hardened steel and finish turning where dimensional stability and surface quality matter.
