Grade BN2000 Characteristics

Sumitomo BN2000 uses uncoated coating tuned for general purpose on steel, hardened steel. The chemistry favors edge stability under interrupted cutting and resists thermal cracking on longer passes.

Features & Benefits

100% Genuine Sumitomo – Original product with full quality guarantee, traceable batch.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Thermal Resistance – uncoated layer holds hardness above typical cutting-zone temperatures.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel, hardened steel interruptions.
Precision Ground – Tight dimensional tolerances for repeatable performance across batches.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

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

Buying Considerations

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

Note: Compatible tool holders sold separately. Please confirm insert-holder seat compatibility (e.g. ISO seat designation) before ordering.
