TNMG160412 AH8015 Tungaloy indexable insert for turning — PVD-coated carbide, 60° triangular geometry

The TNMG160412 AH8015 is an ISO-standard triangular indexable insert designed for external and internal turning of heat‑resistant alloys in industrial machining applications.

Longer tool life and consistent performance for heat‑resistant alloys

The PVD‑coated AH8015 grade provides a balanced combination of wear resistance and edge stability, making it suitable for sustained machining of heat‑resistant alloys. The coating reduces adhesive wear at elevated temperatures and helps maintain a sharp cutting edge for longer intervals, which translates into fewer tool changes and improved process uptime. For production environments where repeatability matters, this PVD-coated carbide grade contributes to predictable tool life and consistent part quality.

Geometry tuned for stability and improved surface quality

The insert’s 60° geometry and 1.2 mm nose radius deliver a reliable compromise between strength and finish when turning. A larger nose radius increases contact area, smoothing surface texture while reducing pressure spikes on the cutting edge; combined with the 0° relief and a plate thickness of 4.76 mm, this geometry enhances rigidity and reduces vibration. The double-sided design and integrated chipbreaker allow two usable cutting edges per index, improving economy without sacrificing stability.

ISO compatibility and easy integration into turning systems

Built as an ISO-standard indexable insert, the plate matches ISO holders when form, relief angle, tolerance class, fixation method, size and thickness align. The cylindrical hole facilitates secure clamping and quick index changes, while the triangular shape ensures straightforward inventory management. Typical system components include the matched external holder or boring bar, an underlay/clamping set and replacement screws; this modular approach reduces setup time and simplifies spindle-side tooling logistics.

Practical benefits for workshop productivity

Selecting the correct chipbreaker and grade for workpiece material and process stability is essential: the AH8015 grade is optimised as a first choice for general machining of heat‑resistant alloys, balancing productivity and cutting-edge life. Reduced downtime through fewer index changes, improved surface finish from stable geometry, and the freedom to apply the insert for both external and internal turning all contribute to lower overall machining costs and greater process reliability.

FAQ

What materials is this insert suitable for?
The TNMG160412 AH8015 Tungaloy indexable insert is intended primarily for machining heat‑resistant alloys and performs well where a balance of wear resistance and edge stability is required.

How many cutting edges does the insert provide?
The triangular, double-sided design offers multiple usable edges per plate, doubling service life compared with single-sided alternatives on the same insert size.

What determines compatibility with a toolholder?
Compatibility depends on form, relief (clearance) angle, tolerance class, fixation method, size and plate thickness; matching these parameters ensures correct fitting and reliable clamping.

Is the nose radius suitable for finishing operations?
A 1.2 mm nose radius provides improved surface finish while maintaining edge strength, making it appropriate for semi‑finishing and many finishing passes depending on machine and process stability.

Can the insert be used for internal machining?
Yes, the ISO standard form and secure cylindrical hole clamping make the insert suitable for both external and internal turning operations when used with the appropriate holder.
