Why Grade NC3120

Korloy’s NC3120 sits between general-purpose and high-performance offerings — strong enough for production rough machining on steel, cast iron, 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.
Diamond Coating – Superior wear resistance and extended tool life under continuous load.
Bulk Pricing Available – Discount tiers for production-volume orders; contact sales.
QC Inspected – Each batch sampled for edge profile, dimensional accuracy, and coating adhesion.
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
Designed for shop conditions typical of Korloy 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 Korloy 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.
