Grade DNC250 Characteristics

Korloy DNC250 uses Diamond coating tuned for high-speed machining on steel, hardened steel. The chemistry favors edge stability under interrupted cutting and resists thermal cracking on longer passes.

Features & Benefits

100% Genuine Korloy – Original product with full quality guarantee, traceable batch.
Diamond Coating – Superior wear resistance and extended tool life under continuous load.
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.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

High-Speed Machining of steel, hardened steel in production CNC lines
Useful for batch production where tool-life predictability matters
Performs across a range of cutting speeds and feed rates
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 Korloy’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.
