Grade AC420K Characteristics

Sumitomo AC420K uses CVD coating tuned for general machining on steel, stainless steel, cast iron, non-ferrous. The chemistry favors edge stability under interrupted cutting and resists thermal cracking on longer passes.

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

Recommended Applications

General Machining of steel, stainless steel, cast iron, non-ferrous in production CNC lines
Performs across a range of cutting speeds and feed rates
Effective in interrupted and continuous cutting passes
CNC lathe and machining center compatible

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.
