CNMG 090402 AH6225 – Tungaloy ISO turning insert, PVD-coated carbide, 80°

The CNMG 090402 AH6225 is an ISO-format rhombic turning insert designed for external and internal turning, providing a balanced combination of a sharp cutting edge and edge stability for variable conditions.

• PVD-coated carbide grade AH6225
• Optimised for rostfreier Stahl machining
• Rhombic CNMG 80° geometry
• Double-sided chipbreaker, cylindrical hole

Consistent performance for rostfreier Stahl turning

The insert is based on a PVD-coated carbide substrate formulated as grade AH6225, which combines a sharp cutting edge with sufficient toughness for medium-duty operations. The coating reduces built-up edge and improves friction behaviour, so the result is a more stable cutting process when machining rostfreier Stahl under varying feed and speed conditions. This means fewer interruptions for edge changes and a steadier surface finish, making the component quality more predictable and repeatable.

Secure seating and ISO compatibility for easy integration

The rhombic CNMG form with an 80° nose angle and a cylindrical hole offers reliable clamping and straightforward compatibility with ISO-standard holders. The defined relief angle and tolerance class ensure the insert seats correctly, which promotes consistent tool orientation and repeatable geometries across batches. As a result, setup times are reduced and tool changes proceed with predictable alignment, supporting efficient shopfloor workflows.

Controlled chip formation for safer, faster cycles

The double-sided chipbreaker geometry is optimised to manage chip shape during both external and internal turning, reducing the risk of entangling long swarf. Improved chip control contributes to safer machining and can support higher uninterrupted cycle times. For operations that prioritise process stability, the combination of chip control and the AH6225 grade supports steady material removal without sacrificing tool life.

Practical benefits for production use

With a corner radius of 0.2 mm and a plate thickness of 4.76 mm, the insert suits medium-precision turning tasks where a fine balance between edge strength and form accuracy is required. The format is double-sided, offering economical indexability, while the PVD coating enhances wear resistance at moderate cutting speeds. For production environments seeking predictable tool performance, this solution offers tangible improvements in uptime and part consistency.

FAQ

What materials is this insert suited for?
The CNMG 090402 AH6225 insert is specified for rostfreier Stahl and is suitable for a wide range of medium-duty stainless steel turning applications thanks to its universal AH6225 grade.

How does the PVD coating benefit machining?
The PVD coating on the AH6225 grade reduces friction and helps prevent built-up edge, which improves component finish and extends the interval between indexings for the Tungaloy turning insert.

Can this insert be used in existing ISO holders?
Yes, the ISO-format CNMG geometry and cylindrical hole ensure compatibility with standard ISO holders when the form, relief angle and tolerance class match the clamping system.

What advantages does the double-sided chipbreaker provide?
The double-sided chipbreaker improves chip control in both external and internal turning, promoting safer machining and enabling longer uninterrupted cutting cycles.

What is the recommended corner radius for fine finishes?
The insert offers a 0.2 mm corner radius, which balances edge strength with the ability to achieve fine surface finishes on turned components.
