Grade KCU25 Performance Profile

Operators running titanium, non-ferrous with the Kennametal KCU25 typically report stable wear progression rather than catastrophic edge loss. The tin system is the reason: it slows abrasion at the rake face while keeping the substrate from softening at the cutting zone.

Features & Benefits

100% Genuine Kennametal – Original product with full quality guarantee, traceable batch.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Edge Stability – Substrate chemistry tuned to limit micro-chipping on titanium, non-ferrous interruptions.
Thermal Resistance – tin layer holds hardness above typical cutting-zone temperatures.
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 titanium, non-ferrous in production CNC lines
Suitable for both wet and dry machining conditions
Effective in interrupted and continuous cutting passes
CNC lathe and machining center compatible

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.

Reminder: Holder rigidity, lead angle, and approach all influence how this insert wears. Pair with a holder rated for the same cutting forces.
