CNMG 120408 AH6225 CNMG Turning Insert by Tungaloy — PVD-coated carbide for stainless steel

The CNMG120408 AH6225 is an ISO‑standard rhombic turning insert designed for external and internal turning operations on stainless steels, offering a balanced combination of a sharp, durable cutting edge and reliable chip control

• PVD-coated carbide grade AH6225
• Optimised for stainless steel turning
• 0.8 mm corner radius for edge strength
• 80° rhombic geometry with central hole

Consistent cutting performance with a PVD-coated carbide grade

The PVD‑coated AH6225 grade delivers a compromise between sharpness and edge stability, making it suitable for stainless steel under medium cutting conditions. The coating reduces adhesion and wear on the cutting edge, which contributes to a steadier cutting action and improved surface finish. For process engineers seeking repeatable results, the combination of a wear‑resistant coating and a purpose‑built substrate reduces tool change frequency and supports predictable cycle times.

ISO compatibility and secure seating for flexible setup

Designed as an ISO CNMG120408 indexable plate, the insert is compatible with holders that match its form, relief angle, tolerance class, fixing method, size and thickness. The rhombic geometry with an 80° included angle, cylindrical central hole and 4.76 mm thickness ensures stable clamping and predictable engagement in external or internal turning. When assembled with the correct holder, shim or clamp set and fastening screws, the system provides the rigidity required to exploit the insert’s geometry and coating benefits.

Efficient chip control and economical re‑indexing

The insert’s double‑sided chipbreaker layout allows two usable edges per side, offering economical use of the carbide body and reduced tooling costs per part. The chipbreaker promotes controlled chip formation across varying cutting conditions, which lessens the likelihood of built‑up edge on stainless steels and supports uninterrupted production. Reindexing doubles serviceable edges and extends the overall life of the insert, contributing to lower tooling expenditure and less downtime for replacements.

Practical selection advice for reliable results

Choosing the correct chipbreaker and corner radius is crucial: the 0.8 mm corner radius offers a compromise between edge robustness and the ability to maintain a fine surface finish under moderate feeds. For marginally unstable set‑ups or interrupted cuts, select a more robust clamping arrangement and consider slightly reduced cutting parameters to preserve edge life. For further material or application matching—such as selecting cutters for different stainless grades or varying stability conditions—Metav Werkzeuge can provide tailored advice and application data.

FAQ

What materials is this insert intended for?
The CNMG120408 AH6225 insert is specified for stainless steel machining; the PVD‑coated AH6225 grade is formulated to handle a wide range of stainless grades under medium cutting conditions.

Is the insert compatible with standard CNMG holders?
Compatibility is governed by form, relief angle, tolerance class, fixing, size and thickness; the CNMG120408 designation indicates ISO compatibility with matching CNMG‑style holders.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius provides a robust cutting edge that increases resistance to chipping while still enabling a good surface finish in many turning applications.

Can both sides of the insert be used?
Yes, the insert features a double‑sided chipbreaker design enabling multiple usable edges and economical reindexing to extend service life.
