TNMG160404 AH6225 — Tungaloy ISO turning insert, PVD-coated, 60° triangular

The TNMG160404 AH6225 is an ISO triangular indexable insert engineered for external and internal turning, offering a balanced combination of sharpness and edge security for medium machining of stainless steels.

• PVD-coated carbide grade AH6225
• Universal for stainless steels
• Two-sided chipbreaker for stability
• 60° triangular insert with 0.4 mm radius

Consistent cutting performance for stainless-steel turning

The combination of the AH6225 grade and a PVD coating provides a measurable benefit in mixed and interrupted turning conditions: a sharp cutting edge that still resists wear under variable loads. As a consequence, the indexable insert achieves repeatable component surfaces and longer intervals between tool changes, which supports higher machine uptime and lower per-part tooling costs. The manufactured carbide substrate delivers the substrate hardness required for medium cutting depths, while the coating reduces adhesive wear when machining stainless steels, so process stability and economy improve in series operations.

Straightforward compatibility with ISO holders to simplify setup

This insert follows the ISO designation and geometric norms, so compatibility is determined by form, relief angle, tolerance class, fixation, size and thickness. The triangular 60° shape with a corner radius 0.4 mm and a 0° relief angle matches common ISO toolholders and boring bars, helping to avoid setup uncertainty. The presence of a cylindrical hole enables secure clamping and accurate repeatability when changing edges. For workshops standardising on ISO tooling, the insert reduces variant complexity and shortens fixture preparation time, improving throughput in mixed-production environments.

Robust geometry and chip control for reliable results

A two-sided chipbreaker design manages swarf formation effectively during medium turning passes, promoting stable chip evacuation and consistent cutting forces. The engineered chip geometry supports predictable behaviour across varying feeds, which is particularly helpful when turning bars with differing stability. The insert’s balanced edge preparation delivers a compromise between initial sharpness and sustained edge life, making it suitable where occasional interruptions or changes in cutting conditions occur. Clear understanding of the chipbreaker function helps set feeds and depths conservatively at first and optimise for productivity as process confidence grows.

Recommended uses and practical guidance for workshop integration

Designed for turning applications, the insert is best used in external and internal operations on stainless steels, selecting the chipbreaker and grade to match component geometry and machine rigidity. For softer workpieces or highly stable setups, larger corner radii and more aggressive feeds can be considered; for slender workpieces or finish passes, maintain conservative feeds to protect the edge. If uncertainty remains about holder compatibility or machining parameters, Metav Werkzeuge provides application advice and can assist with tooling selection to ensure the insert performs efficiently within existing workflows.

FAQ

What materials is the insert suitable for?
The TNMG160404 AH6225 insert is formulated as a universal grade for stainless steels, offering reliable performance in medium turning applications.

Is the insert compatible with standard ISO holders?
Yes, the TNMG160404 designation corresponds to ISO geometry; compatibility is determined by form, relief angle, tolerance class, fixation, size and thickness.

How many usable edges does the insert have?
The triangular insert offers multiple indexing positions; the two-sided chipbreaker supports repeated indexing while maintaining chip control.

Can the insert be used for finishing passes?
The AH6225 grade provides a balance between sharpness and edge strength; for fine surface finishes, use conservative feeds and the 0.4 mm corner radius to reduce vibration.

What does the chipbreaker design achieve?
The two-sided chipbreaker improves chip control and evacuation during medium turning, resulting in steadier cutting forces and more predictable surface quality.
