Grade TNMA433 Performance Profile

Operators running cast iron with the Sumitomo TNMA433 typically report stable wear progression rather than catastrophic edge loss. The al2o3 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.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Edge Stability – Substrate chemistry tuned to limit micro-chipping on cast iron interruptions.
Thermal Resistance – al2o3 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

Rough Machining of cast iron in production CNC lines
Performs across a range of cutting speeds and feed rates
Suitable for both wet and dry machining conditions
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.

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