With a 0.3750″ inscribed circle, the SPG321-BN7000 is a versatile tool for a range of cast iron turning applications, from small to medium-sized workpieces.

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.
Bulk Pricing Available – Discount tiers for production-volume orders; contact sales.
QC Inspected – Each batch sampled for edge profile, dimensional accuracy, and coating adhesion.
Thermal Resistance – uncoated layer holds hardness above typical cutting-zone temperatures.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Finish Machining of cast iron 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.

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.
