Why Grade AC820P

Sumitomo’s AC820P sits between general-purpose and high-performance offerings — strong enough for production finish machining on steel, stainless steel, conservative enough to forgive the occasional spike in feed rate. Diamond layer keeps cutting temperatures workable.

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).
Thermal Resistance – diamond layer holds hardness above typical cutting-zone temperatures.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel, stainless steel interruptions.
Precision Ground – Tight dimensional tolerances for repeatable performance across batches.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Finish Machining of steel, stainless steel in production CNC lines
CNC lathe and machining center compatible
Effective in interrupted and continuous cutting passes
Suitable for both wet and dry machining conditions

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 Sumitomo tooling on a new material.

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