CNMG 090402 AH6225 ISO turning insert — PVD‑coated carbide, 80° rhombic (Tungaloy)

The CNMG 090402 AH6225 is an ISO‑standard rhombic turning insert designed for external and internal turning, offering a sharp yet stable cutting edge for machining rostfreier Stahl and similar materials.

• PVD-coated carbide grade AH6225
• Optimised for rostfreier Stahl machining
• Double-sided chipbreaker for stability
• ISO CNMG geometry, 0.2 mm corner radius

Stable edge life for consistent rostfreier Stahl turning

The PVD-coated grade AH6225 is a mid‑range, carbide‑based cutting material developed for a balance of sharpness and robustness when machining rostfreier Stahl. The physical vapour deposition layer improves wear resistance and reduces built‑up edge, which in turn helps to maintain a consistent cutting edge under varying conditions. Combined with the rhombic ISO geometry and an included angle of 80°, the insert supports steady metal removal rates and predictable tool life, reducing set‑up frequency and downtime.

ISO compatibility simplifies toolholder selection

The ISO designation ensures straightforward interchangeability with standard CNMG toolholders. Compatibility is governed by form, tolerance class, size and thickness; the ISO series approach means holders and clamping sets that accept CNMG‑type inserts will accept this grade without special adaptation. The insert is manufactured with a cylindrical hole, aiding reliable locating and clamping in a wide range of external and internal turning fixtures and borescope holders where secure fastenings are required.

Controlled chip formation and surface quality

A double‑sided chipbreaker delivers consistent chip segmentation for many turning scenarios, improving chip evacuation and reducing heat buildup at the cutting zone. The small 0.2 mm corner radius is suited to finishing and semi‑finishing passes where dimensional accuracy and surface integrity are essential. The plate thickness of 4.76 mm contributes to stiffness in the cutting edge, helping to minimise vibration when performing light to medium cuts. For tougher interruptions or less rigid set‑ups, select a matching holder and adjust feed/speed to preserve the insert’s stable cutting behaviour.

FAQ

What machining tasks is this insert best suited for?
This CNMG 090402 AH6225 insert is designed for external and internal turning operations, particularly where a balance of sharp cutting action and edge stability is required for rostfreie Stahl components.

Is the insert compatible with standard CNMG holders?
Yes, the ISO CNMG geometry of this Tungaloy insert ensures compatibility with standard CNMG toolholders that match the size, thickness and clamping style.

How does the AH6225 grade perform on rostfreie Stahl?
The AH6225 PVD‑coated carbide provides reliable wear resistance and stable cutting edges under the variable conditions typical of rostfreie Stahl machining, helping to reduce built‑up edge and improve process stability.

What finish can be expected with a 0.2 mm corner radius?
A 0.2 mm corner radius offers a fine edge suitable for finishing and light semi‑finishing passes, enabling good surface quality while maintaining dimensional control.

Can the insert be used on internal boring operations?
Yes, the CNMG 090402 geometry and cylindrical hole location are suitable for many internal turning and boring set‑ups when paired with an appropriate holder and clamping system.
