Benefit from the combination of a sharp yet stable cutting edge with the AH6225 PVD-coated carbide grade and a 0.4 mm corner radius for consistent mid-range turning of stainless steels; order directly via Metav Werkzeuge or consult the technical advisors for integration into existing holders.

WNMG 080404 AH6225 WNMG080404‑SM ISO turning insert — PVD‑coated carbide, 0.4 mm radius (Tungaloy)

WNMG080404‑SM AH6225 is an ISO‑standard indexable insert for turning operations, developed for reliable performance in machining stainless steels and variable cutting conditions

• PVD‑coated carbide for improved wear resistance
• Universal grade for stainless steels
• 0.4 mm corner radius for versatile finishing
• Trigon form with cylindrical hole for secure locating

Stable cutting edge for reliable productivity

The PVD‑coated carbide grade AH6225 delivers a combination of a sharp cutting edge and sufficient edge stability, making it suitable for varied turning tasks. This balance reduces the need for frequent index changes and supports steady cycle times when machining rostfreie Stähle (stainless steels). The SM chipbreaker is matched to the grade and process, promoting controlled chip formation in intermittent cutting and changing cutting conditions. By using a universal grade designed for mid‑range parameters, the insert enables consistent surface quality and longer tool life compared with uncoated grades, while minimising unexpected process interruptions.

Designed for secure mounting and straightforward system integration

The insert’s ISO designation and trigon form ensure compatibility with ISO holders when the form, clearance angle, tolerance class, attachment, size and thickness are matched. The 80° geometry and cylindrical hole provide positive locating and stable clamping; the 4.76 mm plate thickness contributes to rigidity in both external and internal turning. For straightforward replacement, the system normally comprises the indexable insert, a matched outside holder or boring bar, a backing/clamp set and spare fastening screws. Clear specification of these interface parameters avoids misfits and supports predictable machining performance.

Practical machining benefits and guidance for selection

A 0.4 mm corner radius provides a practical compromise between edge strength and surface finish: larger radii increase edge life under heavy feed, while smaller radii improve detail and minimise cutting forces in fine finishing. The PVD coating increases resistance to built‑up edge and oxidative wear at elevated temperatures, which is beneficial with stainless steels that tend to work‑harden. For stable results, select the SM chipbreaker and the AH6225 grade to match workpiece material and machining stability; in marginal setups, a slightly reduced cutting speed and controlled feed can further stabilise the process. Original Tungaloy inserts and matched geometries help maintain reproducible outcomes across production runs.

FAQ

What materials is this insert best suited to machine?
The AH6225 grade is formulated as a universal PVD‑coated carbide for machining rostfreie Stähle (stainless steels); it is intended for mid‑range turning applications where a balance of edge sharpness and stability is required.

How does the 0.4 mm corner radius affect performance?
A 0.4 mm corner radius provides a compromise between edge strength and surface finish: it increases robustness compared with a very small radius while still allowing good surface quality in finishing and medium stock removal when using the WNMG080404‑SM insert.

Is the insert compatible with standard ISO holders?
Yes. The WNMG080404‑SM follows ISO geometry; compatibility depends on matching the form, clearance angle, tolerance class, attachment method, size and plate thickness with the chosen holder or boring bar.

What is the advantage of the SM chipbreaker on this grade?
The SM chipbreaker is tuned to the AH6225 grade and stainless steel applications; it encourages controlled chip formation, reduces the risk of built‑up edge and supports consistent surface finish under varying conditions.

Are these original Tungaloy inserts supplied with spare screws or clamps?
System supply typically comprises the insert plus the recommended backing/clamp set and screws as separate items; confirm the exact scope when ordering to ensure the holder and clamping hardware are available.
