Grade KCU25 Characteristics

Kennametal KCU25 uses TiN coating tuned for general turning on steel. 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.
Predictable Wear – Even flank wear pattern simplifies tool-life prediction and scheduling.
Bulk Pricing Available – Discount tiers for production-volume orders; contact sales.
QC Inspected – Each batch sampled for edge profile, dimensional accuracy, and coating adhesion.
Thermal Resistance – tin layer holds hardness above typical cutting-zone temperatures.
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.

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.
