Grade NC3215 Performance Profile

Operators running steel, cast iron with the Korloy NC3215 typically report stable wear progression rather than catastrophic edge loss. The diamond 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 Korloy – Original product with full quality guarantee, traceable batch.
Bulk Pricing Available – Discount tiers for production-volume orders; contact sales.
QC Inspected – Each batch sampled for edge profile, dimensional accuracy, and coating adhesion.
Diamond Coating – Superior wear resistance and extended tool life under continuous load.
Predictable Wear – Even flank wear pattern simplifies tool-life prediction and scheduling.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Rough Machining of steel, cast iron in production CNC lines
Useful for batch production where tool-life predictability matters
Suitable for both wet and dry machining conditions
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 Korloy 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.
