TNMG160408 T6215 TNMG – Turning insert, CVD-coated carbide, 0.8 mm radius (Tungaloy)

The TNMG160408 T6215 is an ISO triangular turning insert designed for external and internal turning of stainless steels under stable to lightly interrupted cutting conditions.

• CVD-coated carbide grade T6215
• Optimised for stainless steels
• Double-sided chipbreaker design
• Triangle insert with 0.8 mm corner radius

Increased tool life and consistent cutting performance

The CVD‑coated carbide grade T6215 provides enhanced wear resistance, which translates into longer intervals between indexings and fewer tool changes. For turning operations that prioritise uptime and reproducible results, this coating reduces flank and crater wear under elevated temperatures typical for machining stainless steels, therefore improving process stability. The result is a measurable improvement in productivity and lower overall tooling consumption when compared with uncoated or less heat-resistant grades.

Reliable fit and simple integration into ISO tooling systems

Provided as an ISO‑standard triangular insert with a cylindrical locating hole and a 0° relief angle, this insert fits conventional holders when form, relief angle, tolerance class, clamping and thickness correspond. The standardised geometry supports quick replacement and predictable positioning, reducing setup time and the risk of incorrect seating. Clear adherence to ISO dimensions ensures compatibility across a range of external holders and boring bars, which helps maintain consistent cutting conditions and surface finish across assemblies.

Better chip control and surface finish for demanding materials

The double-sided chipbreaker is engineered to control chip formation when machining stainless steels, lowering heat concentration at the cutting edge and reducing the likelihood of built-up edge formation. Effective chip control improves coolant access and evacuation, which in turn aids in maintaining a uniform surface quality. Choosing this chipbreaker and the T6215 grade together offers a balance between robustness and surface integrity, particularly useful in applications where rework must be minimised.

Practical guidance for application and set-up

For best results during turning, ensure a stable clamping arrangement and select a holder that matches the insert thickness of 4.76 mm and the insert seat geometry. The 0.8 mm corner radius gives a compromise between strength and edge definition; use it where moderate feed rates and good finish are required. The insert is suitable for both external and internal turning; however, in highly interrupted cuts or when machining very hard or abrasive workpieces, consider a more shock‑resistant grade or altered cutting parameters to preserve edge life and avoid premature chipping.

FAQ

What materials is this insert best suited for?
The TNMG160408 T6215 insert is optimised for machining stainless steels, offering improved wear resistance and process reliability under stable to lightly interrupted cutting conditions.

How does the T6215 coating benefit everyday turning operations?
The CVD‑coated T6215 grade increases thermal and abrasive wear resistance, which extends tool life and supports consistent cutting performance in the Tungaloy turning insert.

Which holders are compatible with this insert?
Compatibility depends on adherence to ISO seat form, relief angle, tolerance class, clamping method and insert thickness; the triangular ISO form and cylindrical hole of this insert match standard ISO external holders and boring bars when dimensions correspond.

What role does the 0.8 mm corner radius play?
A 0.8 mm corner radius offers a balance between edge strength and surface finish, making it suitable for moderate feeds where good surface quality is required without sacrificing robustness.

Is this insert reversible or indexable?
Yes, the triangular shape with double-sided geometry allows indexing to multiple cutting edges, enabling economical use of the insert before replacement.
