TNMG 160404 T6215 TNMG Turning Insert — Tungaloy, CVD-coated carbide, 0.4 mm nose radius

The TNMG160404 T6215 is an ISO triangular indexable insert designed for external and internal turning, optimised for machining stainless steels under stable to mildly interrupted cutting conditions.

• CVD-coated carbide grade T6215
• Triangular ISO TNMG form, 60° cutting angle
• 0.4 mm nose radius for precise finishing
• Double-sided chipbreaker, cylindrical hole

Precision finishing with controlled cutting geometry

The triangular ISO format with a 60° cutting angle delivers a predictable cutting line and repeatable results. The 0.4 mm nose radius balances edge strength with surface quality, enabling fine finishes without sacrificing stability. For users focused on consistent part tolerances, the compact nose radius reduces deflection risk in light to medium cuts while the triangular shape ensures multiple usable cutting edges for economical tool usage. The combination of geometry and edge preparation supports reliable dimensional control and process repeatability.

Durable CVD-coated carbide for stainless steel machining

The CVD-coated carbide grade T6215 provides high wear resistance during the machining of stainless steels, where work hardening and adhesive tendencies can shorten tool life. The coating supports thermal and chemical stability at the cutting edge, reducing built-up edge and maintaining a stable cutting edge over extended cycles. In practice, this means longer consistent tool life, fewer interruptions for tool changes and a more predictable production rhythm for turned components.

Compatibility and secure clamping for workshop flexibility

The insert is delivered in the ISO TNMG160404 format with a cylindrical hole and standard thickness of 4.76 mm, facilitating use with a wide range of external holders and boring bars. Compatibility depends on matching the insert form, clearance angle, tolerance class, clamping method, size and thickness to the chosen holder. The double-sided design with a chipbreaker on each cutting side simplifies stocking and increases the number of available edges per insert, improving inventory efficiency and reducing tooling costs per component.

Practical benefits for production-oriented turning

In production environments, the insert’s wear-resistant grade and robust coating translate to fewer unplanned stops and improved throughput. The combination of CVD-coated carbide, stable geometry and the double-sided chipbreaker contributes to reliable chip control and consistent surface quality. For shops aiming to raise productivity without extensive process rework, this insert supports a pragmatic balance of durability and finishing capability, particularly when machining demanding alloys like stainless steels.

FAQ

What materials is this insert suitable for?
The TNMG160404 T6215 insert is designed primarily for stainless steels, with the CVD-coated carbide grade offering wear resistance suitable for stable to mildly interrupted turning conditions.

Can this insert be used for internal as well as external turning?
Yes. The ISO TNMG160404 format and cylindrical hole enable use in both external holders and appropriate boring bars for internal turning operations.

What does the designation TNMG160404 T6215 indicate?
TNMG identifies the triangular ISO insert form; 160404 denotes the ISO size and geometry; T6215 is the CVD-coated carbide grade optimised for stainless steels.

How does the 0.4 mm nose radius affect machining results?
A 0.4 mm nose radius provides a compromise between surface finish and edge strength, supporting finer finishes while maintaining stability in light to medium cuts.

How to ensure a suitable holder match for this insert?
Select a holder that matches the insert’s form, clearance angle (0° relief as specified for the geometry), tolerance class, clamping method, size and thickness to ensure safe and accurate mounting of the TNMG160404 T6215 insert.
