WNMG080408-SS AH6225 — ISO turning indexable insert, PVD-coated carbide, 80° geometry (Tungaloy)

The WNMG080408-SS AH6225 is an ISO turning indexable insert intended for external and internal turning of stainless steels, offering a balance of sharpness and edge stability for medium cutting conditions

• PVD-coated carbide for stainless steel
• Sharp and stable cutting edge AH6225
• Trigon WNMG insert, 80° cutting geometry

Consistent stainless-steel performance through a balanced grade

The insert is supplied in a PVD-coated carbide grade optimised as a universal solution for stainless steel machining. The AH6225 grade combines a relatively sharp cutting edge with sufficient toughness to tolerate variations in process stability, which results in reliable tool life during medium-duty turning. This balance reduces the frequency of edge changes and supports steady production throughput. The description concentrates on measurable improvements in life and repeatability rather than unsubstantiated claims, giving a clear economic and technical argument for its selection.

Clear guidance on compatibility and clamping for secure use

Compatibility with a toolholder is governed by the insert’s form, clearance angle, tolerance class, clamping method, size and thickness; these factors must match the holder specification. The insert follows the ISO designation for WNMG-style plates, so selecting an appropriate negative holder or boring bar with matching seat geometry ensures correct location and secure clamping. The nominal 0° clearance and trigon profile require holders that accept WNMG dimensions and the specified 4.76 mm plate thickness for safe, repeatable mounting.

Predictable chip control and edge behaviour in varying conditions

Equipped with an SS chipbreaker, the plate promotes manageable chip formation when machining ductile, work-hardening stainless grades. The 0.8 mm corner radius provides a compromise between surface finish and edge robustness, improving resistance to built-up edge while still allowing fine surface quality on many components. The 80° cutting geometry inherent to the WNMG form delivers favourable cutting forces for general turning tasks, making this insert suitable where a stable, general-purpose finishing and medium-roughing capability is required.

Practical selection advice and application scenarios

Specify the chipbreaker and grade to the workpiece material and the machine–fixture rigidity for optimal results. For instance, softer clamping or long overhangs call for a more stable grade or reduced cutting parameters, while rigid set-ups can exploit higher feeds for productivity. If uncertain about the best combination of holder, chipbreaker and cutting data, Metav Werkzeuge offers application-oriented advice and material-specific recommendations to align insert choice with production goals.

FAQ

Is this insert suitable for machining stainless steels?
The WNMG080408-SS AH6225 insert is designed specifically for stainless-steel applications; the AH6225 PVD-coated carbide grade provides a sharp yet stable cutting edge under medium cutting conditions.

Which chipbreaker is fitted and what is its purpose?
The plate carries an SS chipbreaker, engineered to improve chip control and reduce vibration when turning ductile or work-hardening stainless steels with the Tungaloy WNMG080408-SS.

What holders are compatible with this insert?
Compatibility requires a holder that accepts WNMG ISO plates with matching seat geometry, clamping method and thickness; the holder must accommodate the trigon shape and the 4.76 mm plate thickness.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius balances edge strength and surface finish: it increases wear resistance compared with very small radii while still permitting good surface quality in many turning operations.

Can the insert be used for internal turning?
Yes, the insert is suitable for both external and internal turning; selecting the correct holder and cutting data for the workpiece and setup will achieve optimal results.
