CNMG090404 AH6225 indexable turning insert — PVD-coated carbide, 80° rhombic (Tungaloy)

CNMG090404 AH6225 is a PVD-coated indexable turning insert designed for external and internal turning; compatibility is governed by ISO form, clearance, tolerance class, clamping and thickness

• PVD-coated carbide AH6225
• Sharp yet stable cutting edge
• Double-sided chipbreaker
• Rhombic 80° geometry, with hole

Optimised process stability and consistent cutting performance

The PVD-coated carbide grade AH6225 delivers a balance between edge sharpness and robustness that is particularly suited to machining stainless steels under variable conditions. The combination of a defined corner radius (0.4 mm) and a stable cutting edge reduces built-up edge formation and improves surface finish in medium-duty turning. This results in fewer interruptions for insert changes and a more predictable cycle time, which supports higher throughput and lower overall process costs.

Simple integration into ISO holder systems for secure clamping

Designed to the ISO indexable insert standard, the rhombic form and 80° approach angle ensure easy matching to common external holders and boring bars. The presence of a cylindrical hole facilitates positive location and secure clamping, while the insert thickness of 4.76 mm contributes to bending stiffness in interrupted cuts. Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; matching these parameters preserves tool life and ensures repeatable positioning.

Chip control and versatile application in stainless steel turning

The double-sided chipbreaker geometry offers controlled chip formation for the machining strategies typical in turning operations, aiding evacuation and reducing the risk of entanglement. As a universal grade for stainless steels, the design supports both external and internal turning tasks with an emphasis on repeatable performance and surface quality. The indexable format allows rapid turning of inserts to a fresh edge, maintaining productivity in batch and continuous production environments.

FAQ

Is this insert suitable for machining stainless steels?
Yes. The CNMG090404 AH6225 Tungaloy indexable turning insert (SKU TUN6946692) is formulated as a universal grade for stainless steels and is optimised for stable cutting and good surface quality.

Which holder parameters determine compatibility with the insert?
Compatibility is determined by holder form, clearance angle, tolerance class, clamping method, size and thickness; matching these ensures secure seating and repeatable performance with the CNMG090404 AH6225.

Can indexable inserts like this be reground?
Indexable inserts are designed for economical replacement rather than regrinding; the CNMG090404 AH6225 is intended to be rotated or replaced to restore cutting performance.

What chip control does the insert provide?
The double-sided chipbreaker on this insert promotes controlled chip formation and evacuation, supporting safer machining and more consistent surface finishes in turning operations.

Is the insert suitable for both external and internal turning?
Yes; the geometry and hole-mounted design make the CNMG090404 AH6225 suitable for both external and internal turning applications, provided the correct holder and cutting parameters are used.
