TNMG160408 T515 turning insert by Tungaloy — triangular ISO 160408 for turning

The TNMG160408 T515 is a triangular, ISO‑standard indexable insert designed for general external and internal turning operations, particularly optimised for economical machining of cast iron.

• CVD-coated carbide T515 for cast iron
• Triangular shape with cylindrical hole
• Double-sided chipbreaker for versatile use
• 0.8 mm corner radius and 0° clearance

Higher material removal rates with controlled chip formation

The CVD-coated T515 grade combines a wear-resistant surface with substrate strength typical of carbide, enabling higher cutting speeds and stable performance when machining cast iron. This insert is designed to deliver consistent cutting forces and predictable tool life; the double-sided chipbreaker helps control chips in continuous and lightly interrupted cuts, which reduces downtime for chip management and increases component throughput. In practical terms, the result is an optimised balance between productivity and consumable costs.

Simple integration: secure clamping and ISO compatibility

As an ISO 160408 insert, the geometry and dimensions are standardised to fit compatible external holders and boring bars. The triangular form and cylindrical hole permit secure clamping and quick indexation, while the 0° clearance specification must be matched by the chosen holder and tool geometry to ensure correct rake and contact. Compatibility is determined by insert form, relief angle, tolerance class, attachment method, size and thickness; the modular system makes replacement and set‑up straightforward in series production.

Robustness and surface quality for reliable results

With a 0.8 mm corner radius, the design provides a compromise between edge strength and achievable surface finish: larger corner radii increase stability and tool life, while still allowing acceptable roughness on standard cast‑iron components. The carbide substrate with CVD coating resists built‑up edge and abrasive wear common in grey and nodular cast iron, so process windows remain stable over longer intervals. Double‑sided usage halves the cost per usable edge, supporting economic, repeatable machining in high‑volume environments.

FAQ

What materials is this insert best suited for?
The TNMG160408 T515 insert is optimised for machining cast iron; the T515 grade and CVD coating provide wear resistance and chip control tailored to grey and nodular cast irons.

Can the insert be used on both external and internal turning operations?
Yes, the triangular shape and standard ISO dimensions allow use in compatible external holders and boring bars for internal turning, provided holder geometry matches the 0° clearance requirement.

How does the corner radius affect performance?
A 0.8 mm corner radius increases edge strength and enhances tool life while still delivering acceptable surface finish for many roughing and semi-finishing tasks in cast‑iron turning.

Is the insert reversible and how many cutting edges are available?
The insert features a double-sided chipbreaker, allowing rotation to a fresh edge; this design effectively increases the number of usable edges and improves cost efficiency.
