Why Grade KCU25

Kennametal’s KCU25 sits between general-purpose and high-performance offerings — strong enough for production general turning on steel, 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.
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
Precision Ground – Tight dimensional tolerances for repeatable performance across batches.
TiN Coating – Superior wear resistance and extended tool life under continuous load.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel interruptions.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

General Turning of steel in production CNC lines
Useful for batch production where tool-life predictability matters
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.
