TNMG 220412 AH6225 Tungaloy — Indexable turning insert for stainless steels

TNMG 220412 AH6225 is an ISO‑standard triangular indexable insert developed for external and internal turning, offering a robust, sharp cutting edge for variable machining conditions

• PVD‑coated carbide grade AH6225
• Triangular 60° geometry for versatile turning
• Double‑sided chipbreaker for consistent chips
• 1.2 mm nose radius for balanced finish and strength

Efficient, predictable cutting for stainless steels

This insert combines a PVD‑coated carbide substrate with the AH6225 grade to deliver a consistently sharp, wear‑resistant cutting edge adapted to stainless steels. The coating reduces built‑up edge and increases edge stability during variable cutting conditions, which translates into longer edge life and fewer insert changes. Compatibility with ISO holders depends on form, relief angle, tolerance class, fastening and size; the insert’s 60° triangular shape offers a good balance between reach and rigidity for common turning tasks.

Reliable chip control and stable results in medium‑duty turning

Equipped with a double‑sided chipbreaker, the insert ensures predictable chip formation and evacuation, reducing the risk of workpiece surface damage and tool interference. The 1.2 mm nose radius supports improved surface finish without sacrificing edge strength during intermittent cuts. For shops seeking dependable repeatability, this grade and geometry help maintain cycle time and minimise rework, delivering efficiency gains in batch production and flexible job runs.

Practical compatibility and straightforward tooling decisions

Selection of a matching holder should consider the insert’s form, 0° relief angle, tolerance class, fastening method, size and thickness (4.76 mm). The insert is supplied with a cylindrical hole for secure clamping and is designed as a standard ISO turning plate, simplifying integration into existing tool systems. Clear specification of these parameters reduces setup time and ensures stable clamping, which supports higher process reliability and consistent surface quality.
