Grade IC520N Characteristics

Iscar IC520N uses TiCN coating tuned for finish machining on steel, cast iron. The chemistry favors edge stability under interrupted cutting and resists thermal cracking on longer passes.

Features & Benefits

100% Genuine Iscar – Original product with full quality guarantee, traceable batch.
Precision Ground – Tight dimensional tolerances for repeatable performance across batches.
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
TiCN Coating – Superior wear resistance and extended tool life under continuous load.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Finish Machining of steel, cast iron 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 Iscar 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 Iscar tooling on a new material.

Note: Compatible tool holders sold separately. Please confirm insert-holder seat compatibility (e.g. ISO seat designation) before ordering.
