Why Grade KCU25

Kennametal’s KCU25 sits between general-purpose and high-performance offerings — strong enough for production rough machining on steel, conservative enough to forgive the occasional spike in feed rate. Diamond layer keeps cutting temperatures workable.

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).
Thermal Resistance – diamond layer holds hardness above typical cutting-zone temperatures.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Rough Machining of steel in production CNC lines
Performs across a range of cutting speeds and feed rates
CNC lathe and machining center compatible
Effective in interrupted and continuous cutting passes

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.

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