TNMU 120708 AH3135 — triangular indexable insert for milling, PVD-coated carbide, Tungaloy

The TNMU120708 AH3135 is a triangular indexable insert intended for modular TungMeister milling heads and applicable to shoulder, slot, face and contour milling in versatile production environments.

• PVD-coated carbide AH3135 for wear resistance
• Triangular 12 mm insert with 60° cutting angle
• Central hole with cylindrical bore and countersink
• 0.8 mm corner radius for fine contouring

Consistent milling performance with a wear-resistant cutting grade

The insert is produced in the AH3135 grade, a PVD-coated carbide designed to combine edge sharpness with process security. The coating enhances resistance to abrasive wear and reduces edge chipping during interrupted cuts, which leads to longer tool life and fewer index cycles. For operations where predictable performance matters, this geometry and substrate lower the risk of unexpected breakouts and support higher average material removal rates without compromising surface finish.

Geometry tuned for accuracy and chip control

A 60° included angle on a triangular platform provides a stable cutting engagement and an efficient approach for slotting and shoulder operations. The 0.8 mm corner radius helps to balance edge strength with profile accuracy, allowing fine contouring where small radii are required. The insert features a double-sided chipbreaker to improve chip formation and evacuation; coupled with the central hole and the cylindrical bore with a double-sided countersink, the result is repeatable clamping and consistent positional accuracy across index changes.

Modular design that simplifies tool management

Designed for the TungMeister modular milling system, the insert integrates with interchangeable heads and reusable shanks to reduce inventory complexity and set-up times. Replacing only the worn cutting head instead of complete tools lowers tooling costs and shortens downtime. Modular toolsets also permit quick adaptation to varying part geometries and batch sizes, supporting both small-lot flexibility and larger production runs without extensive tooling requalification.

Operational benefits and recommended applications

Intended primarily for milling, the insert suits shoulder, slot, face and contour milling where a sharp cutting edge and stable process are necessary. The 0° free rake and the central mounting design contribute to robust engagement in interrupted cuts and predictable wear patterns, which supports controlled tool life planning. Use this insert where repeatability, chip control and ease of replacement are priorities, particularly in demanding production environments that benefit from modular tool concepts.
