Grade SPU422 Performance Profile

Operators running steel, stainless steel, cast iron, non-ferrous with the Korloy SPU422 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 Korloy – Original product with full quality guarantee, traceable batch.
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
Precision Ground – Tight dimensional tolerances for repeatable performance across batches.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on steel, stainless steel, cast iron, non-ferrous interruptions.
Thermal Resistance – tin layer holds hardness above typical cutting-zone temperatures.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Rough Machining of steel, stainless steel, cast iron, non-ferrous in production CNC lines
Designed for shop conditions typical of Korloy tooling users worldwide
Holds dimensional tolerance over multiple indexings (insert)
Pairs well with through-coolant setups for chip evacuation

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 Korloy tooling on a new material.

Reminder: Holder rigidity, lead angle, and approach all influence how this insert wears. Pair with a holder rated for the same cutting forces.
