Predictable Wear – Even flank wear pattern simplifies tool-life prediction and scheduling.
TiCN/Al2O3 Coating – Superior wear resistance and extended tool life under continuous load.

Buying Considerations

Single-pack option — useful for prototype runs or qualification before bulk commitment. Mid-tier pricing reflects Kennametal’s production-grade tolerances rather than economy substrate.

Tip: Match this insert to a holder whose seat matches the ISO designation. If you’re unsure, send us the holder model and we’ll confirm compatibility before shipping.
