TNMA 220408 T5115 TNMA indexable insert for turning — CVD‑coated carbide, triangular 60° (Tungaloy)

TNMA 220408 T5115 is an ISO‑compliant, triangular insert engineered for external and internal turning, specifically balanced for productive cast‑iron machining.

• CVD‑coated carbide T5115
• Universal grade for cast iron
• Triangular 60° insert geometry
• 0° relief angle with cylindrical hole

High productivity for cast‑iron turning with a universal grade

The combination of a CVD‑coated carbide substrate and the T5115 grade delivers a balanced mix of wear resistance and edge stability, which translates into longer tool life and fewer insert changes during production runs. A CVD coating forms a thin, hard surface layer that reduces adhesive wear and improves resistance to built‑up edge; for customers this means more consistent component tolerances and fewer interruptions. The universal nature of the grade makes it suitable where a single insert type must cover a range of cast‑iron turning tasks, reducing tool inventory and simplifying process planning.

ISO compatibility and secure clamping for consistent results

The insert follows ISO indexing norms, so compatibility with a holder is determined by the insert’s form, 0° relief angle, tolerance class, fastening method, size and thickness. The triangular 60° geometry provides three usable cutting corners, supporting efficient stock removal with reliable seat contact in the pocket. Key dimensions such as 4.76 mm thickness and 22 mm size combine with the cylindrical hole to ensure repeatable mounting and stable cutting forces, which improves surface finish and reduces chatter in standard turning setups.

Practical guidance for everyday workshop use

With a 0.8 mm corner radius the insert balances edge strength and surface finish: the radius improves edge robustness on interrupted cuts and roughing passes, while remaining small enough for acceptable finishes. This variant is supplied without a chipbreaker, so selection of the holder and cutting data should reflect the workpiece condition and rigidity of the set‑up. For optimised process outcomes, pairing the insert with a correctly rated external or boring holder and selecting feeds and speeds for cast‑iron will reduce tool wear and cycle times. Metav Werkzeuge can advise on matching the insert to holders and process parameters to achieve steady, productive machining.

FAQ

What is the primary application of this insert?
The TNMA220408 T5115 insert is designed for external and internal turning, with a universal grade optimised for machining cast iron.

Which materials is the T5115 grade best suited to machine?
T5115 is a universal CVD‑coated carbide grade intended primarily for cast‑iron applications, offering a compromise between wear resistance and edge stability.

How is compatibility with a holder determined?
Compatibility depends on form, relief angle, tolerance class, fastening type, size and thickness; the TNMA220408 requires an ISO‑compatible triangular pocket and a holder that accepts a 22 × 4.76 mm triangular insert with a cylindrical hole.

Does the insert include a chipbreaker?
This variant is supplied without a chipbreaker, so chip control must be achieved via holder geometry or cutting‑parameter adjustments when using the TNMA220408 T5115.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm radius increases edge strength for interrupted cuts and roughing, improving tool life while still allowing reasonable surface quality on finishing passes.
