CNMG 120408 AH6225 — ISO turning insert for turning, PVD‑coated carbide, 80° geometry — Tungaloy

CNMG120408 AH6225 is an ISO‑standard rhombic indexable insert designed for external and internal turning, featuring a 0° clearance angle and a cylindrical hole for secure clamping in compatible holders.

• ISO‑standard rhombic shape, 80° cutting geometry
• PVD‑coated AH6225 for stainless steel machining
• Double‑sided chipbreaker for reliable chip control
• 0.8 mm corner radius for improved surface finish

Higher productivity from a universal PVD grade

The PVD‑coated AH6225 grade is engineered as a universal solution for machining stainless steels, offering a balance between a sharp cutting edge and the robustness required for medium cutting conditions. This combination helps to reduce machining interruptions and maintain dimensional stability across variable batches. The coating enhances wear resistance and adhesion control, which translates into longer edge life and fewer insert changes, supporting a more continuous production flow.

Predictable results through precise geometry and compatibility

The rhombic CNMG shape with an 80° cutting geometry and 0° clearance delivers stable cutting forces and accessible chip evacuation for both external and internal turning applications. The ISO designation and standardised form mean that compatibility with holders is determined by the insert’s shape, clearance angle, tolerance class, fastening method, size and thickness. This predictability simplifies tooling decisions and reduces set‑up time, enabling repeatable part quality and reliable process planning when using the same holder and clamping components.

Practical handling and system benefits for workshop efficiency

Featuring a double‑sided chipbreaker and a 0.8 mm corner radius, the insert supports controlled chip formation and a better surface finish on finished components. The indexable design, together with a 4.76 mm plate thickness and a cylindrical centre hole, allows straightforward clamping in standard external holders or boring bars. As part of an ISO insert system — the insert, holder, shim/clamp set and replacement screws — inventory management is simplified and exchangeovers are fast, reducing downtime and supporting consistent throughput in batch or single‑piece production.

FAQ

Is this insert suitable for machining stainless steels?
Yes. The CNMG120408 AH6225 is a PVD‑coated carbide grade formulated as a universal solution for stainless steels, combining a sharp edge with stable wear resistance for medium‑duty turning.

What holders are compatible with this insert?
Compatibility depends on the holder’s form, clearance angle, tolerance class, fastening type, size and thickness; the insert fits ISO‑standard holders designed for CNMG‑type inserts and an 80° geometry.

How does the double‑sided chipbreaker affect performance?
The double‑sided chipbreaker provides reliable chip control and consistent surface finish, enabling both economical use of the indexable insert and predictable chip behaviour in varying cutting conditions.

Can the insert be used for internal turning / boring operations?
Yes. The rhombic geometry and secure clamping via the cylindrical centre hole make this insert suitable for both external turning and internal operations when mounted in appropriate boring bars.

What are the key dimensions to check before ordering?
Verify the ISO code (120408), corner radius (0.8 mm), plate thickness (4.76 mm) and the 80° cutting geometry to ensure correct fit with the chosen holder.
