Grade BN1000 Performance Profile

Operators running steel, hardened steel with the Sumitomo BN1000 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 Sumitomo – Original product with full quality guarantee, traceable batch.
tin Coating – Superior wear resistance and extended tool life under continuous load.
Predictable Wear – Even flank wear pattern simplifies tool-life prediction and scheduling.
Bulk Pricing Available – Discount tiers for production-volume orders; contact sales.
QC Inspected – Each batch sampled for edge profile, dimensional accuracy, and coating adhesion.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

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

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.

Tip: Match this insert to a holder whose seat matches the ISO designation. If you’re unsure, send us the holder model and we’ll confirm compatibility before shipping.
