TNMU 1207R1 AH3135 – Triangular milling insert for Tungaloy milling systems, PVD-coated carbide, 60°

The TNMU 1207R1 AH3135 is a PVD-coated carbide triangular insert designed for a wide range of milling operations in Tungaloy milling systems, requiring matching insert seats, geometry and cutter bodies.

• PVD-coated carbide AH3135 for wear resistance
• Triangular 12 mm insert with 60° geometry
• Double-sided chipbreaker for controlled chips
• With hole and countersink for secure clamping

Extended tool life through wear-resistant coating and sharp edge

The PVD-coated AH3135 grade is engineered for wear resistance and resistance to edge chipping, which leads to more predictable performance in interrupted and continuous cuts. By combining a fine-grain carbide substrate with a modern PVD layer, the insert maintains a sharp cutting edge for longer periods, reducing unexpected tool changes and supporting steady production flow. This results in improved machine uptime and fewer process interruptions when the insert is used within the specified Tungaloy tool families.

Reliable chip control and secure clamping for stable results

The insert’s double-sided chipbreaker and triangular geometry at 60° provide consistent chip formation across a variety of depths of cut. The central cylindrical hole with a double-sided countersink (40°–60°) ensures precise alignment and secure clamping in compatible cutter bodies, while the 12 mm seat and 7.94 mm thickness contribute to mechanical stability during high-load milling. These design features combine to deliver reproducible surface finish and reduced vibration in demanding milling tasks.

Flexible application range across standard milling tasks

Designed for face, shoulder, slot, high-feed and contour milling (dependent on the assigned tool family), the insert supports diverse production requirements with a single geometry. The triangular form allows three effective cutting edges per index, improving tool utilisation and reducing inventory complexity. When paired with appropriately matched cutter bodies, the insert enables consistent cycle times and high process reliability across multiple component families.

Practical handling and system compatibility

The insert belongs to the milling indexable insert system and must be used with Tungaloy-compatible cutter bodies where the seat, geometry and clamping method are technically identical. The design includes a corner radius of 0 and a clearance angle of 0°, so selection of feed rates and depths of cut should follow the cutter body and machine capability. For customers requiring guidance on selecting the correct insert–body combination, technical consultation is available to ensure the insert’s AH3135 properties are fully exploited in the intended application.
