WNMG080404-ZF AH6225 — ISO turning insert, PVD-coated carbide, 0.4 mm radius (Tungaloy)

The WNMG080404-ZF AH6225 is an ISO-format indexable turning insert optimised for machining stainless steels, featuring a ZF chipbreaker for controlled chip formation in varied conditions

• PVD-coated carbide for stainless steels
• 0.4 mm nose radius for fine surface finish
• ISO-format trigon shape, 4.76 mm thickness
• ZF chipbreaker for stable chip control

Precision and edge stability for continuous production

The AH6225 grade combines a PVD-coated surface with a tough carbide substrate to provide a balance between edge sharpness and wear resistance. This results in a consistently sharp and stable cutting edge during medium cutting depths and fluctuating machining conditions. The 0.4 mm nose radius improves the contact geometry at the tool tip, enhancing surface finish while maintaining sufficient edge strength to avoid premature chipping during interrupted cuts. Such characteristics reduce rework and support steady production throughput.

Optimised chip control and reliable stainless-steel performance

A chipbreaker labelled ZF is designed to break and evacuate chips effectively when machining stainless steels, lowering the risk of built-up edge and thermal work hardening. The AH6225 grade’s coating improves oxidation and adhesive wear resistance, which is particularly relevant for materials prone to work hardening. This combination promotes longer tool life and more predictable tool changes, helping to shorten overall machining cycles and maintain consistent component quality.

ISO-system compatibility for straightforward integration

Compatibility with clamping systems is determined by insert form, relief angle, tolerance class, fastening method, size and thickness. The trigonal (trigon) shape and a thickness of 4.76 mm make the insert suitable for a wide range of ISO-format holders. The insert is supplied with a cylindrical centre hole to match standard locating pins and screws; a complete cutting system requires a matching external holder, shim/clamp set and replacement screws. Clear specification of these parameters simplifies set-up, reduces trial-and-error and ensures reproducible clamping and stiffness in the tool assembly.

FAQ

What materials is this insert suitable for?
The WNMG080404-ZF AH6225 insert (Tungaloy indexable turning insert, SKU 6947528-Tungaloy) is optimised for machining stainless steels, offering reduced adhesive wear and controlled chip formation.

How does the 0.4 mm nose radius affect finish and strength?
A 0.4 mm nose radius improves surface finish by enlarging the contact area and reducing scallop height while retaining sufficient edge strength for medium-duty turning with fewer chipping events.

Which chip control can be expected from the ZF chipbreaker?
The ZF chipbreaker provides reliable chip segmentation and evacuation in varied cutting conditions, reducing the likelihood of long, stringy chips and improving thermal stability during stainless-steel turning.

How to ensure holder compatibility with this ISO insert?
Compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness. Verify the holder accepts WNMG trigon inserts with a 4.76 mm thickness and an 80° included angle.

What distinguishes the AH6225 grade?
AH6225 is a universal PVD-coated carbide grade designed to combine a sharp cutting edge with good stability, making it suitable for changing conditions and reliable performance on stainless steels.
