Features & Benefits

100% Genuine Sumitomo – Original product with full quality guarantee, traceable batch.
Bulk Pricing Available – Discount tiers for production-volume orders; contact sales.
QC Inspected – Each batch sampled for edge profile, dimensional accuracy, and coating adhesion.
Diamond Coating – Superior wear resistance and extended tool life under continuous load.
Predictable Wear – Even flank wear pattern simplifies tool-life prediction and scheduling.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

General Machining of cast iron 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 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.
