Grade KCU25 Characteristics

Kennametal KCU25 uses tin coating tuned for finish machining on non-ferrous. The chemistry favors edge stability under interrupted cutting and resists thermal cracking on longer passes.

Features & Benefits

100% Genuine Kennametal – Original product with full quality guarantee, traceable batch.
Precision Ground – Tight dimensional tolerances for repeatable performance across batches.
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Edge Stability – Substrate chemistry tuned to limit micro-chipping on non-ferrous interruptions.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Finish Machining of non-ferrous in production CNC lines
Effective in interrupted and continuous cutting passes
CNC lathe and machining center compatible
Suitable for both wet and dry machining conditions

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.
