Grade IC520N Performance Profile

Operators running steel, stainless steel, cast iron, heat-resistant with the Iscar IC520N 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 Iscar – Original product with full quality guarantee, traceable batch.
Thermal Resistance – diamond layer holds hardness above typical cutting-zone temperatures.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel, stainless steel, cast iron, heat-resistant interruptions.
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

Finish Machining of steel, stainless steel, cast iron, heat-resistant in production CNC lines
Designed for shop conditions typical of Iscar 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 Iscar 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.
