TNMG 160408 AH725 turning insert by Tungaloy — triangular, PVD-coated carbide for turning

The TNMG160408 AH725 is an ISO-standard turning insert engineered for external and internal turning operations where process security and versatility across steels and stainless steels are required.

• TNMG 160408 AH725 ISO turning insert
• PVD-coated carbide, universal & fracture-resistant
• 60° triangular shape, 0° clearance angle
• Cylindrical hole, corner radius 0.8 mm

Maximise process reliability with a proven ISO geometry

The triangular 60° geometry combined with the ISO-standard designation ensures predictable seating and repeatable cutting conditions in a wide range of holders. The PVD layer on the AH725 grade enhances wear resistance and reduces adhesion during machining, which results in fewer unexpected interruptions and steadier component tolerances. With a 0° clearance angle and a corner radius of 0.8 mm, the insert offers a balance between edge strength and surface finish, making it suitable for applications where dimensional consistency is essential.

Achieve efficient machining across steel and stainless steels

The AH725 grade is a universal, fracture-resistant PVD-coated carbide developed for variable material mixes and demanding production environments. Its double-sided chipbreaker design promotes controlled chip formation, lowering the risk of built-up edge and minimising tool changes. The combination of robust substrate and coating contributes to higher effective tool life and improved overall productivity, particularly when frequent material changes or smaller cutters are in use.

Integrate easily and maintain predictable results

As an ISO turning insert, compatibility depends on form, clearance, tolerance class, fastening method, size and thickness; this insert’s triangular form, 4.76 mm thickness and cylindrical hole support secure clamping in standard external holders and boring bars. The item is supplied in the TNMG160408 ISO format and is suitable for both external and internal turning tasks. Guidance on holder selection and seating tolerance is available to ensure the insert delivers consistent surface quality and repeatable cutting data across production batches.

FAQ

What materials is this insert suitable for?
The TNMG160408 AH725 insert is designed as a universal, fracture-resistant grade primarily for steel and stainless steels, offering reliable chip control and wear resistance across varying alloys.

How does the AH725 coating benefit machining?
The PVD-coated AH725 grade improves surface hardness and reduces adhesion, which helps to maintain edge integrity and extend tool life under mixed-material turning operations.

Is the insert compatible with standard ISO holders?
Yes, the TNMG160408 follows ISO geometry; compatibility is determined by holder form, clearance, tolerance class, fastening and thickness — the 4.76 mm thickness and cylindrical hole support secure clamping in common holders.

What edge preparation is available on this insert?
This item features a 0.8 mm corner radius and a 0° clearance angle, providing a robust cutting edge that balances strength and finish for general turning tasks.
