SNMG 120408-TM OS8235 Turning Inserts

The SNMG 120408-TM OS8235 Turning Inserts are premium-grade double-sided carbide inserts designed for high-efficiency turning operations. Produced with the OS8235 grade, they combine a fine-grain carbide substrate with advanced PVD coating, ensuring exceptional wear resistance, toughness, and thermal stability. This combination allows machinists to achieve consistent results and long tool life, even in demanding applications.

The TM chipbreaker geometry is engineered for medium turning, offering reliable chip control, stable cutting forces, and improved surface finish. These inserts are particularly effective for steels (ISO P20–P35) and stainless steels (ISO M20–M30), covering a broad range of industrial machining needs. With their double-sided design, the SNMG 120408-TM OS8235 Turning Inserts provide multiple cutting edges, making them highly cost-efficient and suitable for continuous production environments.

These inserts are frequently used in the automotive, machinery, and energy industries, where precision and reliability are essential. By combining strength, durability, and versatility, they help reduce downtime and increase productivity across turning operations.
