TNMU 120708 AH3225 – TNMU milling insert for milling, Tungaloy

The TNMU120708 AH3225 indexable insert is a triangular milling grade designed for shoulder, slot, face and contour milling within a modular cutter system.

• Modular milling system with reusable shafts
• PVD-coated carbide grade AH3225 for process security
• Triangular insert with 0.8 mm corner radius
• Double-sided chipbreaker, cylindrical hole + countersink

Reliable geometry for consistent production results

The triangular insert delivers a defined cutting edge geometry with a 60° wedge angle and a 0.8 mm corner radius, ensuring repeatable engagement across interrupted and continuous cuts. The combination of the AH3225 carbide grade and the PVD surface treatment provides enhanced edge stability and wear resistance, which reduces the risk of chipping during shoulder and contour operations. This geometry supports controlled chip formation and contributes to longer tool life, translating into fewer interruptions in the production flow and higher cumulative productivity.

Flexible integration in modular milling setups

As part of the TungMeister modular milling family, the indexable element fits into a system that separates cutting heads from reusable shanks and extensions. This modular approach simplifies tool assembly and inventory: heads can be swapped to match specific operations while shanks remain in service, lowering total tooling cost per part. The insert’s central cylindrical hole with a double‑sided countersink (40°–60°) allows secure and repeatable clamping, enabling straightforward interchangeability of heads and stable fixation under milling forces.

Material and process suitability for demanding tasks

Manufactured from cemented carbide and finished with a PVD coating, this grade is intended for applications that require a sharp cutting edge and reliable performance. The double‑sided chipbreaker design supports efficient chip evacuation across a wide range of feeds and depths of cut, improving surface quality and process stability when machining steels and other common workpiece materials. The robust substrate and coating combination makes the insert suitable for high‑productivity milling where consistent dimensional results and long edge life are priorities.

Practical advantages for machining operations

The triangular format provides three usable cutting edges per face and several indexing positions, reducing downtime for edge changes. The plate thickness of 7.94 mm and the insert size of 12 mm contribute to a solid seat in the milling head, while the 0° clearance angle design offers versatility across different cutter geometries. By choosing an insert that balances sharpness with toughness, operators benefit from a reduction in unexpected edge failure and an improvement in overall machining economy.
