TNMG 160416 AH6225 Tungaloy turning insert — PVD-coated carbide, 1.6 mm radius

TNMG 160416 AH6225 is a triangular ISO turning insert designed for general turning of rostfreier Stahl and other demanding applications

• TNMG form, ISO‑standard insert
• PVD-coated carbide AH6225
• Suitable for rostfreier Stahl machining
• Double-sided chipbreaker with cylindrical hole

Consistent cutting performance for varied turning tasks

The PVD-coated carbide grade AH6225 provides a balanced combination of a sharp, resilient cutting edge and broad material compatibility. Designed for medium turning operations, this insert delivers stable cutting behaviour even under changing conditions, which reduces the need for frequent index changes and supports a steady production flow. The insert form meets ISO standards, so interchangeability with matching holders is straightforward and predictable.

Fast set-up and predictable geometry reduce downtime

The triangular TNMG geometry with a 60° included angle and a 1.6 mm corner radius offers a robust profile that simplifies tool selection and set-up. The insert’s cylindrical hole and standard thickness of 4.76 mm ensure secure clamping and consistent position repeatability in compatible holders. Because compatibility is determined by form, rake/clearance, tolerance class, fastening, size and thickness, the standardised geometry helps to minimise adjustment time and maintain machining accuracy.

Improved chip control and surface quality

Equipped with a double-sided chipbreaker, the insert supports effective chip control, which aids thermal stability and surface finish during both external and internal turning. The chipbreaker design is tuned to the AH6225 grade so that chips are guided away from the cutting zone, reducing the risk of re-cutting and helping to preserve the cutting edge. The result is a measurable benefit in process reliability and a cleaner, more consistent workpiece finish.

Practical guidelines for selection and application

This insert is suitable for a wide range of turning tasks; select the specific chipbreaker variant and holder rigidity according to workpiece stability and machining strategy. The 0° rake angle provides a neutral cutting geometry that performs reliably across different conditions, while the ISO‑standard TNMG form allows use with commonly available external holders or boring bars. For operations where material mix or process stability varies, opt for the AH6225 grade to balance edge sharpness and wear resistance.

FAQ

What operations is this insert designed for?
The TNMG 160416 AH6225 Tungaloy turning insert is intended for external and internal turning, covering general machining tasks where a balance of sharpness and edge stability is required.

Which materials are best suited to this grade?
The AH6225 grade is a universal PVD-coated carbide recommended for machining rostfreier Stahl and similar materials under medium cutting conditions.

How does the double-sided chipbreaker benefit machining?
A double-sided chipbreaker on the TNMG geometry promotes reliable chip control and thermal stability, contributing to improved surface finish and longer edge life.

Is the insert compatible with standard holders?
Yes, the insert follows ISO TNMG form standards; compatibility depends on holder form, clearance, tolerance class, fastening and thickness. Metav Werkzeuge can confirm holder fitment.

What information is needed to order the correct insert?
When ordering, reference the TNMG 160416 AH6225 designation and the manufacturer SKU 6951035-Tungaloy to ensure the correct grade, geometry and hole style are supplied.
