Grade KCU25 Performance Profile

Operators running steel, stainless steel, titanium, inconel with the Kennametal KCU25 typically report stable wear progression rather than catastrophic edge loss. The tialn system is the reason: it slows abrasion at the rake face while keeping the substrate from softening at the cutting zone.

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.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel, stainless steel, titanium, inconel interruptions.
Thermal Resistance – tialn layer holds hardness above typical cutting-zone temperatures.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Finish Machining of steel, stainless steel, titanium, inconel in production CNC lines
CNC lathe and machining center compatible
Effective in interrupted and continuous cutting passes
Suitable for both wet and dry machining conditions

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.
