Grade IC807 Characteristics

Iscar IC807 uses TiN coating tuned for general machining on 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.
QC Inspected – Each batch sampled for edge profile, dimensional accuracy, and coating adhesion.
Bulk Pricing Available – Discount tiers for production-volume orders; contact sales.
Predictable Wear – Even flank wear pattern simplifies tool-life prediction and scheduling.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

General Machining of cast iron in production CNC lines
Performs across a range of cutting speeds and feed rates
Suitable for both wet and dry machining conditions
Effective in interrupted and continuous cutting passes

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.
