TNMG160408 T5105 Tungaloy turning insert

The TNMG160408 T5105 is a triangular, CVD-coated carbide insert designed for external and internal turning, optimised for high-speed machining of cast iron under stable cutting conditions

• CVD-coated carbide for high-speed turning
• Optimised for cast iron machining
• Double-sided chipbreaker for reliable performance
• ISO TNMG 160408 triangular insert, 0.8 mm radius

Consistent chip control for reliable surface quality

The CVD-coated grade T5105 combines a wear-resistant carbide substrate with a hard, thermally stable coating to reduce flank wear and prolong cutting life. The double-sided chipbreaker design promotes predictable chip formation, which simplifies swarf handling and helps maintain a steady cutting force. For machining cast iron, this results in improved surface finish and fewer interruptions, translating into more predictable cycle times and lower tool consumption.

Accurate fit and straightforward mounting reduce setup time

Compatibility with toolholders is determined by insert shape, tolerance class, mounting method and dimensions; the ISO TNMG 160408 form ensures a standardised interface with many external holders and boring bars. The insert features a cylindrical hole for secure fastening and a plate thickness of 4.76 mm, with an inscribed circle of 16 mm, enabling reliable clamping and repeatable positioning. The 0° clearance geometry and the 0.8 mm corner radius support stable contact with the workpiece and predictable wear patterns.

Built for high-speed turning under stable conditions

The combination of a technologically advanced coating and a robust carbide core makes this insert suitable for accelerated cutting regimes when rigidity and process stability are ensured. In such conditions, the grade offers high thermal resistance and consistent edge retention, which reduces the need for frequent index changes. That stability improves throughput and is particularly advantageous for batch production or continuous operations where process security is a priority.

System-level benefits: inventory and process efficiency

As part of an ISO-based system, this insert integrates with compatible holders, underplates, clamping sets and replacement screws, enabling straightforward replacement and simpler stock management. Using a standardised triangular indexable insert reduces the number of distinct toolholders required and keeps logistics lean. The result is a more economical tooling strategy with clear benefits in maintenance, reordering and documentation for production planning.
