Grade BN1000 Performance Profile

Operators running steel, hardened steel with the Sumitomo BN1000 typically report stable wear progression rather than catastrophic edge loss. The uncoated 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 Sumitomo – Original product with full quality guarantee, traceable batch.
Predictable Wear – Even flank wear pattern simplifies tool-life prediction and scheduling.
QC Inspected – Each batch sampled for edge profile, dimensional accuracy, and coating adhesion.
Bulk Pricing Available – Discount tiers for production-volume orders; contact sales.
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Finish Machining of steel, hardened steel in production CNC lines
Suitable for both wet and dry machining conditions
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 Sumitomo tooling on a new material.

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