WNMG080412-TH AH120 — Tungaloy ISO turning insert, trigon, PVD-coated

The WNMG080412-TH AH120 is an ISO trigon turning insert for external and internal turning, providing a wear-resistant PVD-coated carbide grade for process-secure machining.

• PVD-coated carbide AH120 for durability
• Trigon form for versatile turning operations
• 1.2 mm corner radius for robust cutting edge
• Cylindrical hole and 0° clearance angle

Improve throughput with stable edge performance

The trigon geometry combined with the AH120 PVD coating delivers a dependable cutting edge that maintains form under intermittent and continuous cuts. The grade is formulated to be wear- and chipping-resistant, which reduces unplanned tool changes and contributes to predictable cycle times. For shops aiming to raise output without sacrificing surface quality, the combination of PVD coating and a robust carbide substrate helps ensure repeatable results across batches.

Simplified integration into ISO-standard tool systems

Compatibility is determined by the insert’s form, clearance angle, tolerance class, fixation, size and thickness; the insert is built to fit ISO-standard holders when those parameters match. The trigon shape and the central cylindrical hole enable secure clamping on a range of external holders and boring bars, while the 0° clearance angle suits many general turning set-ups. Because the system comprises the insert, a matching external holder or boring bar, and the necessary clamping components, tool change procedures remain straightforward and efficient.

Reliable chip control and surface quality for finishing and roughing

The TH chipbreaker is designed to work with the AH120 grade to manage chip formation across varied steels and cast materials. The 1.2 mm corner radius supports stable cutting in heavier passes while still allowing for acceptable surface finish in finishing cuts. For engineers less familiar with insert metallurgy: PVD coating creates a hard, thin surface layer that increases wear resistance without sacrificing toughness, so the insert combines durability with a sharp initial cutting edge for consistent surface outcomes.

FAQ

What materials is this insert suitable for?
The AH120 grade and TH chipbreaker make the insert suitable for a broad range of materials, including steels and cast materials; the combination is tuned for wear resistance and edge stability in turning operations.

How does the PVD coating benefit performance?
The PVD coating on the AH120 grade provides a hard surface layer that improves wear resistance while maintaining toughness, leading to longer life and more consistent cutting-edge behaviour under typical turning conditions.

Which holders are compatible with this ISO insert?
Compatibility depends on form, clearance angle, tolerance class, fixation, size and thickness; the WNMG080412-TH fits ISO-standard trigon holders and boring bars that match these parameters.

Is the insert suitable for finishing passes?
Yes; the 1.2 mm corner radius and the sharp, PVD-coated cutting edge support good surface quality in finishing passes while offering robustness for heavier cuts.
