CNMG120404 AH6225 CNMG ISO‑120404 — indexable turning insert (for turning) by Tungaloy

A CNMG120404 AH6225 indexable insert designed for ISO‑compliant turning, optimised for turning operations on stainless steels with a robust PVD coating and a 0.4 mm corner radius.

• CNMG120404 indexable insert, ISO format
• PVD‑coated carbide grade AH6225 for stainless steel
• Sharp yet stable cutting edge for medium cuts
• Double‑sided chipbreaker, with cylindrical hole

Consistent performance for stainless‑steel turning

The insert is specified for ISO‑normed turning applications and is supplied in the standard CNMG120404 format, which ensures interchangeability with matching holders. The PVD‑coated carbide composition of grade AH6225 delivers a balance between sharpness and edge stability, making it suitable for variable cutting conditions encountered when machining stainless steels. Compatibility depends on holder form, clearance angle, tolerance class, fastening and insert thickness, so the system must include a matching external holder, shim/clamp set and replacement screws for a secure assembly.

Reduced downtime through a stable cutting edge

A combination of a sharp cutting geometry and a robust substrate gives the insert predictable wear behaviour during medium machining. The double‑sided chipbreaker design helps to control chip formation and evacuation, reducing the risk of built‑up edge and improving surface finish consistency. These characteristics translate into longer effective cutting life and fewer tool changes, supporting improved process efficiency and reduced machine downtime.

Practical system integration and handling benefits

The insert’s cylindrical hole and ISO form simplify clamping and indexation in standard turning toolholders. The specified 0° clearance angle and 80° insert angle are relevant when selecting tool paths and approach angles to maintain cutting stability. When combined with the correct holder geometry and clamping components, the insert supports reliable repeatability and straightforward reconditioning steps, which is advantageous in production settings where predictable results and quick tool swaps are required.

FAQ

Is this insert suitable for machining stainless steels?
Yes. The CNMG120404 AH6225 insert is supplied in grade AH6225, a PVD‑coated carbide formulated as a universal choice for stainless steels and designed to provide a sharp yet stable cutting edge under variable conditions.

Which turning operations are recommended?
External and internal turning are the typical applications; the CNMG120404 geometry and double‑sided chipbreaker support medium machining tasks where chip control and surface finish consistency are required.

What are the key dimensions to check when selecting a holder?
Check the insert size (12 mm), thickness (4.76 mm), corner radius (0.4 mm), clearance angle (0°) and the cylindrical hole form to ensure the insert seats and clamps correctly in the chosen holder.

How does the PVD coating improve performance?
The PVD coating on the AH6225 grade enhances wear resistance and helps maintain a stable cutting edge at elevated temperatures, which contributes to longer tool life and consistent surface quality when turning stainless steels.

Can the insert be indexed or reversed during use?
The insert features a double‑sided chipbreaker and a secure central hole for mounting; correct clamping in a compatible ISO‑compliant holder enables indexing according to the holder’s specification.
