Grade IC8350 Characteristics

Iscar IC8350 uses DIAMOND coating tuned for high-speed machining on cast iron, heat-resistant. 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.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Edge Stability – Substrate chemistry tuned to limit micro-chipping on cast iron, heat-resistant interruptions.
Thermal Resistance – diamond layer holds hardness above typical cutting-zone temperatures.
Precision Ground – Tight dimensional tolerances for repeatable performance across batches.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

High-Speed Machining of 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. Mid-tier pricing reflects Iscar’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.
