TNMU 070304 AH120 triangular indexable insert for milling (Tungaloy)

TNMU070304 AH120 is a triangular indexable insert for milling systems, intended for plan, shoulder, groove, high-feed and contour operations when used in a matching milling body.

• PVD-coated carbide grade AH120
• Triangle indexable insert, size 07
• Plate thickness 3.18 mm for secure clamping
• 60° cutting angle and 0.4 mm corner radius

Consistent cutting-edge performance for stable production

The triangular indexable insert is designed to support process reliability in milling applications where a sharp edge and consistent results are required. The PVD coating on the carbide substrate improves wear resistance while preserving a defined cutting geometry, which helps to maintain surface quality and dimensional stability over repeated indexings. For users integrating this insert into compatible milling bodies, the combination of coating and substrate reduces the frequency of index changes, supporting uninterrupted production cycles.

Secure seating and adaptable clamping for safe operation

A secure clamping interface is essential for safe, repeatable milling. This insert features a cylindrical hole with a double-sided countersink (40°–60°) and a 3.18 mm plate thickness, providing a rigid seat when used with the correct clamping screw and, where applicable, a locating shim. The triangle form offers multiple indexable edges, enabling economical use of each insert while the 0.4 mm corner radius balances edge strength with the ability to produce accurate contour and shoulder geometries.

Optimised grade for demanding milling conditions

The AH120 grade is a PVD-coated, wear- and breakage-resistant specification developed for milling tasks that demand a sharp cutting edge together with reliable tool life. In practice, this grade supports a wide range of operations—planing, shoulder, grooving, high-feed and contour milling—provided the insert seat, geometry and tool body are matched. The 60° geometry contributes to efficient chip control and engagement angles suitable for many common milling strategies, helping to reduce tool-related process variation.
