Features & Benefits

100% Genuine Sumitomo – Original product with full quality guarantee, traceable batch.

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 steel, cast iron, hardened steel 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 Sumitomo tooling users worldwide

Buying Considerations

Single-pack option — useful for prototype runs or qualification before bulk commitment. Mid-tier pricing reflects Sumitomo’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.
