CNMG 120404 AH6225 Tungaloy indexable insert for turning applications

A CNMG 120404 AH6225 Tungaloy indexable insert designed for external and internal turning, optimised for stainless steels with a sharp yet robust cutting edge and ISO compatibility

• ISO rhombic CNMG 80° geometry
• PVD-coated carbide AH6225 for stainless
• 0.4 mm corner radius for finishing
• Double-sided chipbreaker, with cylindrical hole

Reliable cutting for stainless‑steel turning

The insert’s PVD‑coated carbide composition (AH6225) delivers a balance between edge sharpness and wear resistance tailored for stainless steels. This grade is engineered to maintain a stable cutting edge under fluctuating cutting conditions, which reduces downtime for insert changes and supports consistent surface quality. The PVD layer enhances thermal resistance and adhesion, meaning sustained performance at medium cutting depths and during interrupted cuts, while the double‑sided design extends usable life per insert.

Geometry and chip control that improve productivity

The CNMG 120404 form with its 80° included angle provides a versatile approach angle for a wide range of turning tasks, improving axial engagement and stability. The 0.4 mm corner radius is ideal for fine finishing passes where dimensional accuracy and edge integrity matter. The built‑in double‑sided chipbreaker manages chip flow for stainless‑steel machining, assisting in predictable chip formation and evacuation; this reduces rework and contributes to a smoother production flow when paired with the correct clamping system.

Easy integration into ISO tool systems and workshop routines

As an ISO‑standard insert, the component fits established holders when form, clearance angle, tolerance class, fixation method, size and thickness match. The cylindrical hole supports secure clamping on compatible toolholders and simplifies replacement logistics. With a plate thickness of 4.76 mm and a nominal size 12, the insert integrates into common turning systems and allows rapid changeover, supporting higher machine uptime and simpler inventory management. Selecting this indexable insert with the appropriate chipbreaker and cutting parameters enables stable, economic machining in serial production.

FAQ

What materials is this insert best suited for?
The insert is optimised for stainless steels; the AH6225 PVD‑coated carbide composition provides good edge stability and wear resistance for medium cutting operations.

Can the CNMG 120404 fit existing toolholders?
Yes — compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness; the CNMG 120404 follows ISO dimensions for straightforward integration.

How does the 0.4 mm corner radius affect the finish?
A 0.4 mm radius offers a balanced finish capability, reducing cutting forces for fine surface quality while maintaining edge strength for repeatable dimensions.

Is the chip control suitable for interrupted cuts?
The double‑sided chipbreaker is designed to promote controlled chip formation during typical turning and can perform well under interrupted cutting when paired with correct parameters.

What indicates longer tool life with this grade?
The combination of PVD coating and the AH6225 substrate enhances thermal stability and wear resistance, which supports longer in‑service life and consistent performance
