TCMT 090204-SL OS8225 Turning Inserts

The TCMT 090204-SL OS8225 Turning Inserts are high-quality carbide inserts designed for precision turning applications. Manufactured with the OS8225 grade, these inserts provide a strong balance between toughness and wear resistance, making them suitable for a wide range of steels and stainless steels. The advanced PVD coating delivers high thermal stability and extended tool life, ensuring consistent performance even under interrupted cutting conditions.

The SL chipbreaker geometry is optimized for light to medium turning, providing excellent chip control and smooth cutting action. It helps reduce vibration, improves surface finish, and ensures stability when machining at higher spindle speeds. This makes the TCMT 090204-SL OS8225 Turning Inserts an excellent choice for both continuous and slightly interrupted cuts.

These turning inserts are particularly effective for ISO P25–P35 steels and ISO M20–M30 stainless steels. Thanks to their fine-grain carbide substrate combined with the OS8225 coating, they maintain cutting edge sharpness while resisting deformation. They are widely used in general machining, automotive components, and precision engineering industries.
