Grade IC8250 Characteristics

Iscar IC8250 uses Diamond coating tuned for medium turning on steel, stainless steel. 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.
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
Precision Ground – Tight dimensional tolerances for repeatable performance across batches.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel, stainless steel interruptions.
Thermal Resistance – diamond layer holds hardness above typical cutting-zone temperatures.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Medium Turning of steel, stainless steel in production CNC lines
Useful for batch production where tool-life predictability matters
Performs across a range of cutting speeds and feed rates
Effective in interrupted and continuous cutting passes

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.

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