Sumitomo 3NUWNGA432 BN350 – Turning Carbide Insert

The Sumitomo 3NUWNGA432 BN350 turning carbide insert excels in general machining applications for steel and hardened steel workpieces, with its tin coating providing a balanced mix of wear resistance and toughness. This insert is particularly suited for turning operations where a strong, sharp cutting edge is required, and its 80-degree trigon angle allows for efficient material removal and a smooth finish. With a corner radius of 0.0313″ and an inscribed circle of 0.5000″, it’s ideal for a wide range of turning tasks on steel and hardened steel workpieces.

Features & Benefits

100% Genuine Sumitomo – Original product with full quality guarantee, traceable batch.
QC Inspected – Each batch sampled for edge profile, dimensional accuracy, and coating adhesion.
Bulk Pricing Available – Discount tiers for production-volume orders; contact sales.
Predictable Wear – Even flank wear pattern simplifies tool-life prediction and scheduling.
tin Coating – Superior wear resistance and extended tool life under continuous load.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

General Machining of steel, hardened 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 Sumitomo’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.
