TNMA 220404 T5125 Turning Insert (indexable), CVD-coated carbide, 60° — Tungaloy

TNMA220404 T5125 is an ISO‑compliant triangular indexable insert engineered for external and internal turning where interrupted cuts and less stable conditions demand a tougher grade

• TNMA 220404 geometry, 60° triangular
• CVD-coated carbide T5125 grade
• Suited for interrupted cuts in cast iron
• Cylindrical hole for secure clamping

Productivity and wear resistance for interrupted turning

The TNMA220404 T5125 insert combines a CVD coating with a wear‑resistant carbide substrate to extend tool life under demanding conditions. The selected T5125 grade is formulated for tougher engagement such as interrupted cuts in cast iron, offering improved chip control through material behaviour rather than an integrated breaker. For manufacturing operations this means fewer tool changes and more consistent cycle times, which supports efficient spindle uptime and predictable process output.

Precise geometry ensures stable clamping and repeatable results

With a 60° triangular form and a corner radius of 0.4 mm, the insert provides a balance between strength and edge engagement suitable for a wide range of turning tasks. The cylindrical hole supports secure fastening with standard clamping sets, while the plate thickness of 4.76 mm and size 22 define compatibility with ISO holders. Describing how compatibility is determined: form, free angle (0°), tolerance class, fastening, size and thickness must match the intended holder — selecting the correct combination reduces vibration and improves surface finish.

Clear application guidance for process reliability

The grade and geometry are chosen for metalcutting scenarios where robustness matters more than maximum material removal rate. The absence of a dedicated chipbreaker means chip management must be addressed through cutting parameters and stable workholding; nevertheless, the T5125 composition delivers stable chip formation in cast iron and similar materials. For production environments this translates into reproducible machining windows and reliable part quality, especially where interrupted cuts or variable setup rigidity are present.

System approach and practical integration into the tool set

An effective cutting system comprises the ISO insert, a compatible external holder or boring bar, an appropriate shim/clamping set and replacement screws. The insert's ISO designation simplifies procurement and interchangeability across machines and suppliers. Metav Werkzeuge can advise on the matching holder geometry and clamping hardware to ensure correct insert seating and to maximise the life of both insert and toolholder while maintaining dimensional accuracy on the workpiece.

FAQ

What materials is this insert suitable for?
The TNMA220404 T5125 insert (Tungaloy indexable turning insert, SKU 6853042-Tungaloy) is primarily intended for cast iron and similar materials where a tougher grade benefits interrupted cutting.

How is compatibility with a toolholder determined?
Compatibility depends on form, free angle (0°), tolerance class, fastening method, size and thickness; matching these parameters to the holder ensures secure seating and correct cutting geometry.

Does the insert include a chipbreaker for chip control?
No, this insert is supplied without a chipbreaker; chip management relies on the combination of grade behaviour, cutting parameters and effective workholding.

Is the TNMA geometry suitable for internal as well as external turning?
Yes; the triangular 60° form and the cylindrical hole allow use in suitable external holders and boring bars for internal turning when the holder accepts ISO TNMA inserts.

What components are required for a complete cutting system?
A full system comprises the ISO insert, a matching external holder or boring bar, an underlay/clamping set and the appropriate replacement screws to ensure correct clamping and repeatable performance.
