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.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel, hardened steel interruptions.
Thermal Resistance – diamond layer holds hardness above typical cutting-zone temperatures.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
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
Performs across a range of cutting speeds and feed rates
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. Mid-tier pricing reflects Korloy’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.
