TNMA 160404 T5125 indexable turning insert (60°) by Tungaloy

A TNMA160404 T5125 indexable turning insert designed for general turning, providing a robust solution for cast iron machining under interrupted cuts and less-stable set-ups

• CVD-coated carbide grade T5125
• 60° triangular geometry for stable cutting
• 0.4 mm corner radius for fine profiling
• ISO TNMA 160404 compatible with standard holders

Consistent cutting performance for interrupted cuts

The CVD-coated carbide grade T5125 is formulated for cast iron machining where chip control and edge stability are critical, especially during interrupted or unstable cuts. The coating enhances wear resistance and thermal stability, which supports longer edge life and fewer tool changes. The triangular 60° geometry delivers predictable engagement and contributes to steady cutting forces, while the 0.4 mm corner radius produces a refined profile on the workpiece. Compatibility with the toolholder depends on form, clearance angle, tolerance class, mounting, size and thickness, so matching the insert to the correct holder is essential for reliable results.

Straightforward system integration and mounting reliability

Designed to the ISO TNMA 160404 standard, the insert has a nominal size of 16 mm and a plate thickness of 4.76 mm, together with a cylindrical mounting hole, which eases alignment and repeatable clamping in standard external holders or boring bars. The insert is supplied without a chipbreaker, allowing selection of a dedicated chip-control geometry when required for specific materials or cutting conditions. A complete system typically comprises the insert, a suitable external holder or boring bar, a shim/clamp set and the correct fastening screws to ensure optimum seating and repeatable tool life.

Process security, productivity and application guidance

When selected and paired correctly, this grade provides improved process security and reduced downtime through fewer insert changes. The combination of CVD coating and a robust carbide substrate promotes stable chip formation in cast iron, translating into consistent surface finish and predictable tool-cost per component. For shops seeking reliable, production-proven performance in turning operations, this insert supports efficient, repeatable machining. For further guidance on selecting the appropriate chipbreaker or holder combination for specific alloys, consult the technical advisers at Metav Werkzeuge.

FAQ

What materials is this insert suitable for?
The Tungaloy TNMA160404 T5125 insert is optimised for cast iron machining and performs well in interrupted cuts or less-stable set-ups thanks to the CVD-coated carbide grade T5125.

Does the insert include a chipbreaker?
This ISO TNMA 160404 insert is supplied without a chipbreaker, allowing the choice of a dedicated chip-control geometry to match the specific material and machining conditions.

Which holder types are compatible with TNMA160404 inserts?
Compatibility is determined by form, clearance angle, tolerance class, mounting, size and thickness; TNMA160404 inserts are compatible with ISO-designated external holders and boring bars sized for 16 mm triangular inserts.

What are the key dimensional features to check when replacing an insert?
Verify the insert designation (TNMA160404), plate thickness (4.76 mm), corner radius (0.4 mm) and the presence of a cylindrical mounting hole to ensure correct seating and clamp engagement.

How does the T5125 grade affect tool life and finish?
The T5125 CVD coating on the carbide substrate improves thermal stability and wear resistance, which can extend tool life and produce consistent surface finish in cast iron turning.
