CNMG 120408 AH6225 — Turning insert by Tungaloy (ISO turning insert)

CNMG120408 AH6225 Tungaloy-Wendeplatte is a PVD-coated indexable insert for general turning applications, optimised for rostfreier Stahl and medium machining.

• PVD-coated carbide grade AH6225
• Optimised for rostfreier Stahl machining
• Rhomboid CNMG form, 80° included angle
• Double-sided chipbreaker for reliable chips

High-precision performance for demanding turning tasks

The insert delivers a balance of a sharp, stable cutting edge and wear resistance thanks to its PVD-coated carbide grade AH6225. This combination is designed to maintain cutting-edge integrity under variable cutting conditions, which translates into consistent part quality and reduced rework. For operations on rostfreier Stahl, the coating and substrate interaction reduces built-up edge and supports predictable flank wear, enabling longer tool life in medium-duty turning.

Designed to fit standard ISO holders and secure clamping systems

The CNMG120408 geometry follows ISO norms, ensuring straightforward compatibility with holders that match in form, clearance, tolerance class, fastening method, size and thickness. The rhomboid form with an 80° included angle offers versatility for both external and internal turning profiles. The insert’s cylindrical hole and standard dimensions simplify replacement and indexing, reducing machine downtime and easing inventory management for production environments.

Operational advantages and economical machining

A double-sided chipbreaker and the grade’s stability support reliable chip control and repeatable surface finishes during medium machining. The insert’s 0.8 mm corner radius offers a compromise between edge strength and surface finish, while the plate thickness of 4.76 mm contributes to rigidity in interrupted cuts. Together, these characteristics promote productive machining cycles, predictable tool life and a favourable cost-per-part ratio for series production.

FAQ

What materials is this insert suitable for?
The CNMG120408 AH6225 insert is optimised for rostfreier Stahl but the AH6225 grade and PVD coating also perform well across a range of steels in medium machining.

How does the coating improve performance?
The PVD-coated finish on the AH6225 grade enhances wear resistance and reduces adhesion on the cutting edge, which improves consistency and edge life during turning operations with rostfreier Stahl.

Is the insert reversible or single-sided?
This CNMG insert features a double-sided chipbreaker, allowing indexing to additional cutting edges for extended usability and economical operation.

Which holder characteristics determine compatibility?
Compatibility depends on holder form, clearance (0° free angle in this insert), tolerance class, fastening method, size and thickness; the ISO CNMG format ensures broad suitability with standard holders.

What surface quality can be expected with a 0.8 mm corner radius?
A 0.8 mm corner radius balances edge strength and finish quality, delivering reliable surface results for medium machining without excessive tool stress.
