SNMG120408-MM 2025 Sandvik Carbide Inserts High Wear Resistance

SNMG120408-MM 2025 Turning Insert | High-Wear-Resistance Sandvik Insert for Steel Machining

The SNMG120408-MM 2025 is a premium square turning insert from Sandvik Coromant, designed for high-efficiency machining of steel (ISO P) and selected stainless steels (ISO M). Manufactured with the advanced 2025 carbide grade, this insert combines a tough substrate and a highly wear-resistant PVD coating. It delivers excellent performance in terms of wear resistance, crater wear control, thermal stability, and consistent tool life—ideal for both continuous and light-interrupted turning.

The MM (Medium Machining) chip-breaker provides smooth cutting action, optimized chip formation, and reduced cutting forces. This promotes better surface finish, enhanced process stability, and longer insert life. The SNMG square insert with negative-rake geometry offers four strong cutting edges, delivering durability and reliability for roughing to semi-finishing operations.
