Why Grade NC3120

Korloy’s NC3120 sits between general-purpose and high-performance offerings — strong enough for production interrupted cutting on steel, stainless steel, conservative enough to forgive the occasional spike in feed rate. Diamond layer keeps cutting temperatures workable.

100% Genuine Korloy – 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.
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

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

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.
