VNMG 120402 AH8015 – ISO rhombic turning insert, PVD‑coated carbide, 0.2 mm nose radius, by Tungaloy

VNMG120402E‑TF AH8015 is an ISO rhombic turning insert engineered for external and internal turning of heat‑resistant alloys, offering a balance of wear resistance and cutting‑edge stability for general machining tasks

• ISO‑standard rhombic insert VNMG120402
• PVD‑coated carbide AH8015 for heat‑resistant alloys
• 0.2 mm nose radius for fine profiling
• With cylindrical hole for secure clamping

Consistent edge stability for challenging alloys

The PVD‑coated carbide grade AH8015 is specified for the general machining of heat‑resistant alloys, delivering a balanced mix of wear resistance and edge stability. This composition helps to maintain cutting performance at elevated temperatures and reduces the frequency of insert changes. By choosing an insert with these properties, workshops achieve more predictable tool life and steadier surface quality on demanding materials.

Precision fit and secure clamping reduce setup variability

The rhombic insert geometry combined with a cylindrical hole and defined dimensions ensures a repeatable mechanical fit in compatible holders. Key parameters—0° clearance angle, 35° approach angle, plate thickness 4.76 mm and 12 mm nominal size—determine compatibility with external toolholders and boring bars. Matching holder form, tolerance class, clamping method and thickness prevents micro‑movement at the cutting edge, which in turn reduces vibration and improves dimensional accuracy.

Optimised chip control for uninterrupted production

The integrated TF chipbreaker promotes predictable chip formation when paired with an appropriate feed and depth of cut, aiding evacuation and reducing recutting. Improved chip control lowers the risk of workpiece damage and tool interference, contributing to higher productivity and fewer machine stops. Selecting a chipbreaker and grade tailored to the workpiece material and machining stability yields the best combination of feed rates and surface finish.

Practical compatibility and selection guidance for the workshop

As part of an ISO insert system, the component is intended for use with a matching external holder or boring bar, in conjunction with a shim/clamping set and replacement fastening screws. Typical uses include both external and internal turning where a balanced grade is required. For applications requiring higher stability or different surface demands, consult the available holder options and consider feed adjustments rather than frequent insert swaps to keep cycle times efficient.

FAQ

What materials is this insert best suited for?
The VNMG120402E‑TF AH8015 is designed primarily for heat‑resistant alloys, offering a compromise between wear resistance and cutting‑edge stability for general turning operations.

Which holders are compatible with this insert?
Compatibility is determined by holder form, clearance angle, tolerance class, clamping method, size and plate thickness; the insert suits ISO‑standard external toolholders and boring bars specified for VNMG‑type rhombic plates.

How does the TF chipbreaker affect machining?
The TF chipbreaker promotes controlled chip formation, improving chip evacuation and reducing the risk of recutting, which supports longer uninterrupted cutting and better surface finishes.

Is the insert suitable for both external and internal turning?
Yes, the insert is intended for both external and internal turning, provided the holder and clamping system match the insert’s shape and dimensions.

What are the key dimensional values to check before ordering?
Check the plate size (12 mm), plate thickness (4.76 mm), nose radius (0.2 mm), approach angle (35°) and clearance angle (0°) to ensure proper fit and performance.
