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

A WNMG080404-PS AH6225 ISO turning insert for external and internal turning, designed to deliver a sharp yet robust cutting edge in variable machining conditions.

• PVD-coated carbide AH6225 for rostfreier Stahl
• WNMG trigon insert, size 08, 0.4 mm radius
• 0° relief angle and cylindrical central hole
• ISO‑standard 080404 for broad holder compatibility

Consistent cutting performance with a universal PVD grade

The AH6225 grade is a PVD‑coated carbide developed as a universal solution for machining rostfreier Stahl. Its coating stabilises the cutting edge under fluctuating temperatures and feeds, while the substrate maintains toughness to resist chipping. The result is a combination of sharp cutting edge and stable tool life, helping to reduce insert changes and maintain consistent surface finish in medium‑duty turning operations. For production runs with varying workpiece stability, this balance improves overall process reliability and can lower unit machining costs.

Robust geometry and secure clamping for repeatable results

The trigon form with an included angle of 80° and a 0.4 mm corner radius provides a strong, wear‑resistant cutting contour that performs well on external and internal profiles. The insert thickness of 4.76 mm and the cylindrical hole allow secure clamping in matched holders and boring bars, supporting high positional repeatability. Because compatibility depends on form, relief angle, tolerance class, attachment method, size and thickness, using ISO‑standard inserts simplifies holder selection and changeover in mixed‑machine environments, enabling faster setup and fewer handling errors.

System approach and controlled chip formation for safer turning

The PS chipbreaker in the designation is tailored for medium cuts and promotes predictable chip control when machining rostfreier Stahl, which often produces long, ductile chips. Incorporating the insert into a complete system—insert, matched external holder or boring bar, shim/clamp and replacement screws—ensures correct seat and torque for best performance. Select the chipbreaker and grade according to the workpiece material and machining stability to optimise surface finish and tool life.
