Why Grade IC520N

Iscar’s IC520N sits between general-purpose and high-performance offerings — strong enough for production general machining on steel, carbon steel, conservative enough to forgive the occasional spike in feed rate. tin layer keeps cutting temperatures workable.

Features & Benefits

100% Genuine Iscar – Original product with full quality guarantee, traceable batch.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Thermal Resistance – tin layer holds hardness above typical cutting-zone temperatures.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel, carbon steel interruptions.
Precision Ground – Tight dimensional tolerances for repeatable performance across batches.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

General Machining of steel, carbon steel in production CNC lines
Useful for batch production where tool-life predictability matters
Performs across a range of cutting speeds and feed rates
CNC lathe and machining center compatible

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.

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.
