CNMG090404 AH6225 CNMG turning insert for Drehen — Tungaloy, PVD-coated carbide, rhombic shape

The CNMG090404 AH6225 is an ISO-standard rhombic turning insert designed for external and internal turning, offering a sharp yet robust cutting edge optimised for rostfreier Stahl.

• PVD-coated carbide grade AH6225
• Universal for rostfreier Stahl machining
• Rhombic CNMG with 0.4 mm corner radius
• Double-sided chipbreaker, cylindrical hole

Reliable cutting performance for rostfreier Stahl and mixed conditions

The insert delivers a balance of sharpness and edge stability thanks to the PVD-coated carbide grade AH6225, which is formulated for medium-depth turning under varying conditions. This combination reduces the need for frequent tool changes and supports more consistent cycle times, improving process reliability. The engineered cutting edge produces predictable chip formation, making the system suitable for a broad range of rostfreier Stahl components where surface finish and repeatability matter.

ISO compatibility and secure mounting for predictable results

Designed to ISO dimensions, the rhombic CNMG geometry and the cylindrical hole ensure straightforward compatibility with standard holders and boring bars. Correct selection of holder form, clearance angle, tolerance class and clamping set determines seating precision; when paired correctly, the system reduces vibration and runout, supporting dimensional accuracy. The insert’s double-sided design also allows indexable usage, extending effective tool life and lowering tooling costs per part.

Material and coating explained for non-specialists

The substrate is a fine-grain carbide and the surface receives a PVD coating that increases wear resistance while preserving a sharp cutting edge. In practical terms, this means improved edge life when machining rostfreier Stahl and fewer interruptions for dressing or replacement. The 0° clearance and the 0.4 mm corner radius contribute to a smooth transition between passes and help protect the edge during interrupted cuts or variable feed conditions.

Operational benefits and application guidance

Using this insert in a stable setup yields tangible benefits: reduced spindle idle time, more predictable tool-change intervals and reproducible surface quality. For external and internal turning, choose feeds and cutting speeds tailored to the grade AH6225 and the specific rostfreier Stahl alloy; this maximises chip control provided by the double-sided chipbreaker. If process stability is limited, prioritise a rigid clamping arrangement and conservative cutting parameters to exploit the insert’s robust edge behaviour.

FAQ

What materials is this insert best suited for?
The CNMG090404 AH6225 insert is designed primarily for machining rostfreier Stahl and performs well across a broad range of stainless alloys when cutting parameters are adapted.

How does the AH6225 coating help in production?
The PVD-coated AH6225 grade on the CNMG090404 improves wear resistance and maintains a sharp edge, extending tool life and supporting consistent surface finish during medium-depth turning.

Can the insert be indexed, and how many cutting edges are available?
This rhombic CNMG insert is double-sided and indexable, allowing multiple cutting edges to be used before disposal, which reduces tooling costs per edge.

What holder features are important for optimal performance?
Holder form, tolerance class, correct clamping set and rigid mounting are essential for the CNMG090404 to minimise runout and vibration, ensuring precise cutting and chip control.
