Bulk Pricing Available – Discount tiers for production-volume orders; contact sales.
QC Inspected – Each batch sampled for edge profile, dimensional accuracy, and coating adhesion.
Predictable Wear – Even flank wear pattern simplifies tool-life prediction and scheduling.
TiN Coating – Superior wear resistance and extended tool life under continuous load.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Interrupted Cutting of steel, stainless steel, titanium, non-ferrous in production CNC lines
Pairs well with through-coolant setups for chip evacuation
Holds dimensional tolerance over multiple indexings (insert)
Designed for shop conditions typical of Kennametal tooling users worldwide

Buying Considerations

Single-pack option — useful for prototype runs or qualification before bulk commitment. Entry-tier pricing makes this a low-risk option for trialing Kennametal tooling on a new material.
