CNMG090408 AH6225 ISO turning insert — PVD-coated carbide, 80° rhombic by Tungaloy

A CNMG090408 AH6225 ISO rhombic turning insert engineered for external and internal turning, offering a sharp yet robust cutting edge for medium machining of stainless steel and similar materials.

• PVD-coated carbide AH6225 for stainless steel
• Double-sided chipbreaker for predictable chip control
• 80° rhombic geometry with 0.8 mm corner radius
• Cylindrical hole and ISO compatibility for standard holders

Increased process efficiency through a balanced grade and coating

The combination of a PVD-coated carbide grade and a geometry tailored to medium cutting conditions results in predictable tool life and consistent part quality. The AH6225 grade is formulated to maintain a sharp, stable cutting edge under variable conditions, which reduces the need for frequent insert changes and supports uninterrupted production. For manufacturers seeking measurable gains in throughput, this grade translates into fewer tool indexings and a smaller number of tool changes over a production run, improving overall machining efficiency.

Geometry and mounting that simplify toolset selection

The 80° rhombic geometry and the insert’s dimensions (size 09, thickness 4.76 mm) ensure compatibility with the majority of ISO-standard turning holders. The 0° clearance angle and the 0.8 mm corner radius deliver a balance between good edge strength and fine surface finish capability. A cylindrical hole and standard clamping interface make retrofit and replacement straightforward: compatibility is determined by form, clearance angle, tolerance class, clamping method, size and thickness, so holders and shims must be checked against those parameters before assembly.

Stable chip control and surface quality for repeatable results

This insert’s double-sided chipbreaker design improves chip formation across a range of cutting depths and feed rates, helping to avoid built-up edge and uncontrolled chips when turning stainless steel. The PVD layer enhances wear resistance and retains edge integrity during medium machining, supporting stable cutting conditions and a consistent surface finish. For shops that value repeatability, the result is fewer rejected parts and a more economical tool-per-part ratio.

Practical notes for application and selection

Intended for both external and internal turning operations, the insert performs best when paired with an appropriate chipbreaker and holder suited to the workpiece stability and machining strategy. Select the chipbreaker and grade according to the material being machined and the rigidity of the set-up; the insert is optimised for medium cutting and changing conditions rather than extreme high-speed or ultra-heavy interrupted cuts. If uncertain about the best combination of holder, shim and clamping screws, the Metav Werkzeuge technical team can provide guidance tailored to the machining scenario.

FAQ

Which materials is the insert suitable for?
The AH6225-grade insert is designed primarily for stainless steel and similar alloys; the PVD coating and carbide substrate provide a balance of wear resistance and edge stability in medium machining conditions.

How does the CNMG090408 geometry affect performance?
The 80° rhombic shape and 0.8 mm corner radius offer a compromise between edge strength and finish, while the 0° clearance angle and standard thickness support broad compatibility with ISO holders.

Is the insert reversible or indexable?
The insert is double-sided with a chipbreaker on both effective edges, allowing indexation for extended tool life and efficient use of each insert.

What should be checked for holder compatibility?
Compatibility depends on insert form, clearance angle, tolerance class, attachment method, size (09) and thickness (4.76 mm); confirm that the holder matches these parameters before mounting.
