CNMG 120408 AH6225 ISO turning insert by Tungaloy — PVD-coated carbide, 80° rhombic

A CNMG 120408 AH6225 indexable insert designed for general-purpose turning, providing a sharp, stable cutting edge for medium machining of rostfreier Stahl and similar materials.

• ISO rhombic 80° geometry
• PVD-coated carbide AH6225
• Universal for rostfreier Stahl turning
• Double-sided insert with cylindrical hole

Consistent machining with a PVD-coated, stable cutting edge

The combination of a PVD-coated carbide substrate and the AH6225 grade results in a cutting edge that balances sharpness with wear resistance. This balance reduces flank wear under varying conditions and extends effective tool life, which supports predictable cycle times and lower tooling costs. For shops processing rostfreier Stahl in mixed-batch production, the controlled performance of this insert contributes to repeatable surface finish and reduced rework, making it a pragmatic choice for medium-turning operations seeking stability and economy.

Geometry that suits a wide range of turning tasks

The 80° rhombic shape with a 0.8 mm corner radius and 0° clearance facilitates both external and internal turning while enabling comfortable approach angles on shoulders and profiles. The double-sided chipbreaker offers two usable cutting edges, improving indexable economy, and the ISO format ensures compatibility with standard holders when form, tolerance and fastening match. Together, these attributes provide flexible cutting behaviour and dependable chip control for varied part geometries without sacrificing process reliability.

Easy integration into ISO-based tool systems

Compatibility is determined by plate form, freestanding angle, tolerance class, fastening, size and thickness; this insert follows those ISO conventions for straightforward replacement and setup. The system comprises the ISO insert, a matching external holder or boring bar, shim/clamp set and replacement screws, which simplifies inventory and reduces downtime during changes. As an indexable insert, it enables quick edge changes and predictable cost per part, supporting lean production and efficient machining workflows.
