Why Grade KCU25

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

Features & Benefits

100% Genuine Kennametal – Original product with full quality guarantee, traceable batch.
TiN Coating – Superior wear resistance and extended tool life under continuous load.
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).
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

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

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.
