Why Grade KCU25

Kennametal’s KCU25 sits between general-purpose and high-performance offerings — strong enough for production rough machining 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.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel, cast iron, non-ferrous interruptions.
Thermal Resistance – tin layer holds hardness above typical cutting-zone temperatures.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Rough Machining of steel, cast iron, non-ferrous in production CNC lines
Useful for batch production where tool-life predictability matters
Performs across a range of cutting speeds and feed rates
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.

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.
