TNMG160408 AH6225 Tungaloy insert — ISO turning insert, PVD‑coated carbide for turning

A TNMG160408 AH6225 indexable turning insert designed for external and internal turning, offering a sharp yet stable cutting edge for stainless steels in medium cutting conditions.

• PVD‑coated carbide grade AH6225
• 60° triangular geometry for stable cutting
• Double‑sided chipbreaker for adaptable use
• ISO compatibility with cylindrical hole

Consistent edge life with a universal stainless‑steel grade

The AH6225 PVD‑coated carbide delivers a balanced combination of sharpness and robustness tailored to stainless steels. The coating improves wear resistance and thermal stability, which translates into more consistent edge life during medium‑range operations. With a 0.8 mm corner radius and a 60° insert angle, the geometry supports predictable cutting forces and a controlled engagement with the workpiece; this reduces chatter and helps maintain surface finish without frequent index changes. The result is improved process reliability and lower overall tooling expenditure per component.

Easy integration into ISO turning systems reduces downtime

As an ISO‑standard insert, the component sits within a clear system: the insert, a matching outer holder or boring bar, shim/lock set and replacement screws. Compatibility is governed by shape, clearance angle, tolerance class, fastening, size and thickness, so the insert fits directly into familiar tooling setups when the holder matches these parameters. The cylindrical hole and triangular form make mechanical location straightforward, while the double‑sided chipbreaker allows reversible indexing for extended usage. This compatibility shortens changeover times and simplifies inventory management on the shop floor.

Predictable chip control and application flexibility

The integrated double‑sided chipbreaker is designed to perform under varying cutting conditions, enabling repeatable chip formation when machining medium feeds. The PVD coating enhances edge stability at elevated temperatures, which is beneficial for interrupted cuts or varying cut depths. The insert is suitable for both external and internal turning operations; selecting the correct chipbreaker and grade according to workpiece material and machining stability ensures the best outcome.
