TNMG 160408 T5125 TNMG Turning insert by Tungaloy — CVD-coated carbide, 60°

The TNMG160408 T5125 Tungaloy insert is an ISO triangular turning insert designed for external and internal turning, optimised for interrupted cuts and less stable setups.

• CVD-coated carbide grade T5125
• ISO triangular insert, 60° geometry
• 0.8 mm corner radius for robust cuts
• Double-sided chipbreaker with central hole

Stable cutting in interrupted and less rigid conditions

The combination of a CVD-coated surface with a wear-resistant carbide substrate provides enhanced resistance to thermal and mechanical loading during interrupted machining. This grade is formulated for applications in cast iron where chip formation can be unpredictable; the coating supports stable cutting forces and improved edge life. The direct benefit is fewer tool-indexing operations and more consistent part quality when machining discontinuous sections or unstable setups.

Fast integration into ISO tool systems for predictable setups

Standardised ISO geometry and the 60° triangular form ensure straightforward compatibility with common turning holders when form, relief angle, tolerance class, fastening and thickness match. The insert’s central cylindrical hole and prescribed plate thickness permit secure clamping and repeatable positioning, reducing setup time and minimising runout risks. This leads to higher process reliability and easier inventory handling for production environments that rely on ISO-indexable tooling.

Controlled chip formation and reinforced cutting edge

The double-sided chipbreaker design supports consistent chip control across a range of cutting conditions, while the 0.8 mm corner radius gives the cutting edge extra strength against impact and shock during interrupted cuts. Together, these features enable a balance between surface quality and robustness: stable chip evacuation reduces recutting, and the reinforced corner lowers the risk of premature edge chipping, which is particularly beneficial in less rigid assemblies.

Practical application guidance for turning operations

Intended for both external and internal turning, the insert performs best when paired with an appropriate holder and matched chipbreaker tailored to the workpiece material and stiffness of the setup. For cast iron applications and frequent interrupted cuts, the selected grade and chipbreaker promote reliable span formation and predictable tool life. When integrating into a system, confirm the holder’s relief angle and clamping method align with ISO specifications to maintain repeatable accuracy and secure fixation.

FAQ

What materials is this insert suitable for?
The TNMG160408 T5125 insert is formulated for machining cast iron and performs well under interrupted cutting conditions due to its CVD-coated carbide grade.

Is the insert compatible with standard ISO holders?
Compatibility depends on holder form, relief angle, tolerance class, fastening and thickness; the ISO triangular design of the TNMG160408 supports standard ISO tool systems when these parameters match.

How does the chipbreaker affect performance?
The double-sided chipbreaker on the TNMG160408 promotes controlled chip formation and evacuation, improving surface finish and reducing the risk of recutting in interrupted operations.

Does the insert offer reinforced edge strength for roughing tasks?
The 0.8 mm corner radius increases edge robustness, making the TNMG160408 more resistant to impact and suitable for less stable machining conditions.

How is the insert fixed to the toolholder?
The TNMG160408 features a central cylindrical hole for secure clamping; correct matching of holder type and fastening hardware ensures repeatable positioning.
