TNMU 120708 AH120 Tungaloy indexable insert for milling — triangular 12 mm, 60°

The TNMU 120708 AH120 is a triangular indexable insert designed for the TungMeister modular milling system, intended for shoulder, slot, face and contour milling with interchangeable heads and reusable shanks.

• TungMeister modular system compatible
• PVD-coated AH120 cemented carbide
• Sharp cutting edge for secure milling
• Triangular 12 mm insert, 0.8 mm radius

Engineered for consistent edge life and process stability

The modular insert is manufactured from PVD-coated AH120 cemented carbide, a grade developed to combine wear resistance with robust edge behaviour. The coating reduces flank wear and improves adhesion of the cutting edge, providing longer tool life and consistent performance in interrupted or continuous milling. For manufacturing operations where repeatability and low scrap rates matter, this composition supports a controlled material removal rate and predictable regrind intervals.

Built for fast tool changes and lower tooling costs

Designed as part of the TungMeister modular milling family, the insert enables quick head swaps and re-usage of shafts, cutting machine setup time and overall tooling expenses. The insert’s mounting features — including a cylindrical hole with double-sided countersink (40°–60°) — ensure secure clamping in the cutter head and accurate seating during indexation. This leads to reduced downtime and easier inventory management for production shops that require flexible, application-led tooling.

Precision geometry for predictable surfaces and chip control

The triangular cutting geometry with a 0.8 mm corner radius and a 60° cutting wedge delivers a balance between strength and finish quality: the radius supports higher feed rates and edge stability, while the wedge angle helps maintain consistent cutting forces. The double-sided chipbreaker controls chip formation across a range of materials, improving evacuation and surface finish during operations such as shoulder and face milling. Plate dimensions and a thickness of 7.94 mm provide a stable seat in the cutter head, contributing to repeatable part tolerances.

FAQ

What applications suit this triangular insert best?
The TNMU 120708 AH120 insert is intended for shoulder, slot, face and contour milling in modular cutter systems, offering process-secure performance for a wide range of milling tasks.

How does the AH120 grade affect tool life?
The AH120 PVD coating on the cemented carbide substrate improves wear resistance and supports a sharp cutting edge, which extends effective insert life under standard milling conditions.

Is the insert compatible with modular heads and reusable shafts?
Yes — the insert is part of the TungMeister modular concept and is designed for use with interchangeable milling heads and reusable shanks for easier changeovers.

What chip control can be expected from this geometry?
The double-sided chipbreaker promotes consistent chip formation and evacuation, resulting in improved surface quality and reduced risk of chip-related damage during milling.
