Grade AC420K Performance Profile

Operators running steel, stainless steel, cast iron, non-ferrous with the Sumitomo AC420K typically report stable wear progression rather than catastrophic edge loss. The tin system is the reason: it slows abrasion at the rake face while keeping the substrate from softening at the cutting zone.

Features & Benefits

100% Genuine Sumitomo – Original product with full quality guarantee, traceable batch.
Thermal Resistance – tin layer holds hardness above typical cutting-zone temperatures.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel, stainless steel, cast iron, non-ferrous interruptions.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
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
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. Entry-tier pricing makes this a low-risk option for trialing Sumitomo tooling on a new material.

Tip: Match this insert to a holder whose seat matches the ISO designation. If you’re unsure, send us the holder model and we’ll confirm compatibility before shipping.
