WNGU 090408 AH120 Tungaloy indexable milling insert — trigon form, PVD-coated carbide, 80° cutting angle

A WNGU 090408 AH120 indexable insert for milling applications, designed for face, shoulder, slot, high-feed and contour milling within matching Tungaloy cutter systems

• PVD-coated carbide AH120 for wear resistance
• Trigon form for stable clamping and seating
• Double-sided chipbreaker for controlled chips
• Cylindrical hole with countersink (40°–60°)

Reliable wear resistance for consistent production

The PVD-coated AH120 grade combines a wear- and breakage-resistant carbide substrate with a hard coating that stabilises the cutting edge under cyclical loads. This results in improved edge life and process security during medium to demanding milling operations. The coating reduces adhesive wear and helps maintain dimensional accuracy over longer tool life, which supports predictable machining cycles and fewer tool changes.

Geometry that secures the cutting edge and chip control

The trigon plate form with an 80° cutting angle and a 0.8 mm corner radius offers a secure seat in compatible milling bodies and a reliable transition between cutting edges. The double-sided chipbreaker on this insert controls chip formation on both cutting faces, helping to reduce rework and improve surface finish. A 0° clearance angle and a plate thickness of 4.76 mm contribute to robust edge support and stability under axial and radial loads.

System compatibility and assembly advantages

This insert is intended for Tungaloy milling systems; the system build comprises a milling body, the indexable insert, a clamping screw and, where required, an underlay shim. The insert is supplied with a cylindrical hole and a double-sided countersink (40°–60°), facilitating secure clamping and repeatable positioning. Correct matching of seat geometry and cutter family is essential for safe operation and to realise the insert’s full performance potential.

Application range and process benefits

Suitable for face, shoulder, slot, high-feed and contour milling depending on the assigned cutter family, the insert supports a wide material spectrum when paired with the AH120 grade. Benefits include fewer interruptions for tool changes, improved surface quality and stable cutting-edge behaviour under mixed cutting conditions. For complex jobs, the indexable design allows rapid edge indexing, reducing downtime and increasing throughput.

FAQ

What materials can be machined with this insert?
The AH120 grade PVD-coated carbide is designed for a broad range of milling tasks; when mounted in a suitable Tungaloy cutter, the insert performs well in general steel and mixed-material milling operations.

How is the insert secured in the milling body?
The insert has a cylindrical hole with a double-sided countersink (40°–60°) and is clamped with a clamping screw; correct plattensitz and matching geometry of the milling body ensure repeatable seating.

What advantages does the double-sided chipbreaker provide?
The double-sided chipbreaker on the insert controls chip formation on both cutting faces, improving chip evacuation and surface quality while lowering the risk of built-up edge.

Is the insert compatible with all Tungaloy milling bodies?
Compatibility requires matching of seat, geometry and cutter family; the insert is intended for Tungaloy milling systems and should only be used in technically compatible bodies.

Can the insert be indexed to use both sides?
Yes, the design allows indexing of the usable cutting edges; the double-sided chipbreaker and trigon form support multiple edge usage, increasing effective tool life.
