VNMG 120408 AH6225 VNMG – ISO 120408 turning insert, PVD-coated carbide, Tungaloy

The VNMG120408E-ZM AH6225 is a rhombic ISO turning insert designed for external and internal turning, offering a universal cutting grade for stainless steels and medium cutting conditions.

• PVD-coated carbide grade AH6225
• Designed for stainless steels
• Rhombic ISO insert 12 mm size
• 0.8 mm corner radius, 0° clearance

Efficient cutting for stainless steels with a stable edge

The rhombic indexable insert combines the AH6225 grade with a PVD coating to provide a consistently sharp yet durable cutting edge for turning applications in stainless steels. The engineered balance between toughness and wear resistance means fewer unplanned changes during medium-duty operations, supporting predictable tool life and improved process yields. As an ISO-series component, the insert contributes to standardised tooling setups that simplify inventory and reduce machine downtime.

Compatibility and system guidance for reliable clamping

Compatibility with toolholders is governed by form, relief angle, tolerance class, fastening method, size and thickness; this ISO insert adheres to those conventions for straightforward integration into existing turning systems. The ISO 120408 designation, rhombic form and specified thickness allow straightforward selection of a matching external holder, clamping kit and replacement screw. Clear information about the insert geometry enables process planners to select the correct holder and minimise set-up time while ensuring secure clamping and repeatable positioning.

Chip control and operational benefits that save time

Equipped with the ZM chipbreaker and a compact 0.8 mm corner radius, the insert is tailored for controlled chip formation under varying conditions, reducing the risk of entanglement and improving surface finish in many stainless steel turning tasks. The 0° relief angle supports geometric stability in face and profile turning, while the central hole with a cylindrical form ensures reliable location and fastening. These features combine to lower cycle variability and contribute to smooth production flow with predictable maintenance intervals.

FAQ

Which materials is this insert suitable for?
The VNMG120408E-ZM AH6225 insert is formulated primarily for stainless steels, with the AH6225 PVD-coated carbide grade offering balanced wear resistance and edge stability for medium machining.

How does the ZM chipbreaker affect performance?
The ZM chipbreaker on this indexable insert promotes predictable chip formation in mixed turning conditions, improving surface finish and reducing chip management issues during production.

What geometry must the holder match for correct use?
Holders must match the insert form, relief angle, tolerance class, fastening method, size (12 mm) and thickness (4.76 mm); these parameters ensure secure clamping and correct positioning of the VNMG120408E-ZM AH6225.

Is this insert compliant with ISO specifications?
Yes—this product is part of an ISO indexable turning insert series and carries the ISO 120408 designation, facilitating compatibility with standardised tooling systems.

What are the key dimensional data to check before ordering?
Verify the corner radius (0.8 mm), insert size (12 mm), thickness (4.76 mm), relief angle (0°) and the presence of the cylindrical central hole to ensure fit with the intended holder.
