TNMA 160412 T5115 Turning Insert – Tungaloy ISO triangular turning insert for external and internal turning

The TNMA160412 T5115 Tungaloy turning insert is an ISO‑standard triangular indexable insert designed for general turning applications, especially suited to cast iron where a balance of wear resistance and edge stability is required.

• CVD-coated carbide T5115
• Universal grade for cast iron
• ISO TNMA 160412 format
• Triangular insert with central hole

Consistent performance for cast‑iron turning

The insert’s CVD‑coated carbide grade T5115 combines wear resistance with edge stability to extend tool life in serial and batch turning operations. This universal grade is tailored for a broad range of grey and nodular cast irons, reducing the need for frequent insert changes and improving uptime. The triangular geometry and the 1.2 mm corner radius produce a robust cutting edge that tolerates variable feed and depth conditions while maintaining dimensional repeatability; for users unfamiliar with coatings, CVD (Chemical Vapour Deposition) applies hard, wear‑resistant layers that protect the carbide substrate during abrasive and high‑temperature cutting.

Easy integration with ISO toolholders and secure clamping

Compatibility is determined by form, clearance angle, tolerance class, attachment method, size and thickness; the ISO TNMA 160412 format ensures interchangeability with standard holders and boring bars. The insert features a cylindrical central hole for positive seating and secure clamping, supporting stable tool engagement and reduced vibration. The specified 0° clearance angle suits many external turning set‑ups where a neutral relief improves contact geometry, and the 4.76 mm thickness gives adequate support in heavier cuts, translating into reliable surface finish and predictable tool life.

Practical benefits and machining economy

Using a grade optimised for cast iron and a standardised TNMA form simplifies inventory management and tool changeover procedures. The insert’s balanced performance often leads to longer intervals between indexings and fewer unexpected tool interventions, which improves productivity and lowers per‑part tooling costs. For process planning, note that this variant has no dedicated chipbreaker, so cutting parameters should be chosen to ensure effective chip evacuation in the chosen workholding and coolant arrangement. The combination of ISO conformity, Tungaloy material science and the insert’s geometry supports stable, repeatable turning results across series production.

FAQ

What materials is this insert best suited for?
The TNMA160412 T5115 Tungaloy turning insert is optimised for cast iron machining thanks to the T5115 grade, while also delivering stable performance in a range of related materials.

Does the insert include a chipbreaker for improved chip control?
This variant is supplied without a chipbreaker; chip evacuation relies on appropriate cutting parameters and the machine’s coolant and clamping configuration.

Which holder types are compatible with this TNMA format?
ISO‑compliant external holders and boring bars that accept TNMA 160412 inserts with a cylindrical central hole are compatible; compatibility depends on form, tolerance class and attachment method.

How does the CVD coating benefit cutting performance?
The CVD coating on the T5115 grade increases wear resistance and protects the carbide substrate at elevated temperatures, resulting in extended tool life and consistent edge stability during turning.

Can this insert be used for internal turning as well as external turning?
Yes, the insert’s geometry and standard ISO format make it suitable for both external and internal turning applications when paired with the correct holder or boring bar.
