Grade TN620 Performance Profile

Operators running steel, stainless steel with the Kyocera TN620 typically report stable wear progression rather than catastrophic edge loss. The tin 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 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.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel, stainless steel interruptions.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Finishing of steel, stainless steel in production CNC lines
Pairs well with through-coolant setups for chip evacuation
Designed for shop conditions typical of Kyocera tooling users worldwide
Holds dimensional tolerance over multiple indexings (insert)

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.
