Grade CA525 Characteristics

Kyocera CA525 uses Cvd coating tuned for high-speed machining on steel, stainless steel. The chemistry favors edge stability under interrupted cutting and resists thermal cracking on longer passes.

Features & Benefits

100% Genuine Kyocera – Original product with full quality guarantee, traceable batch.
Precision Ground – Tight dimensional tolerances for repeatable performance across batches.
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
Cvd Coating – Superior wear resistance and extended tool life under continuous load.
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

High-Speed Machining of steel, stainless steel in production CNC lines
Useful for batch production where tool-life predictability matters
Suitable for both wet and dry machining conditions
Effective in interrupted and continuous cutting passes

Buying Considerations

Single-pack option — useful for prototype runs or qualification before bulk commitment. Mid-tier pricing reflects Kyocera’s production-grade tolerances rather than economy substrate.

Reminder: Holder rigidity, lead angle, and approach all influence how this insert wears. Pair with a holder rated for the same cutting forces.
