TCMT 110204-SL OS8226 Carbide Turning Insert

The TCMT 110204-SL OS8226 is a precision carbide turning insert designed for finishing and semi-finishing operations. With its 60° triangular shape (T-type) and positive geometry, it offers low cutting forces, excellent surface finish, and stable chip control, making it ideal for light-duty turning.

The OS8226 grade features a fine-grained carbide substrate with a PVD coating, providing excellent wear resistance and heat stability. This makes the insert particularly well-suited for machining steels, stainless steels, and non-ferrous metals under stable conditions. The SL chipbreaker is optimized for light to medium cutting, ensuring efficient chip evacuation and minimal vibration.

The 110204 designation indicates a 11 mm inscribed circle, 2.38 mm thickness, and a 0.4 mm nose radius, providing accuracy for detailed turning and profiling. Commonly used in precision engineering, automotive, and aerospace industries, this insert delivers consistent tool life and superior surface quality.
