WNMG080408‑SM AH725 – ISO turning insert (trigon, PVD‑coated) by Tungaloy

WNMG080408‑SM AH725 provides a universal, out‑break resistant turning solution for external and internal turning across steels and stainless steels

• PVD-coated universal grade AH725
• Robust trigon geometry for secure clamping
• 0.8 mm corner radius for edge strength
• Compatible with ISO holders and shims

High process security from a universal PVD‑coated grade

The WNMG080408‑SM AH725 is a PVD‑coated carbide insert engineered for versatile turning tasks. The AH725 grade offers a balance between toughness and wear resistance, making it suitable for both steel and stainless steels in mixed‑material batch work. The coating improves surface integrity and extends tool life under varying cutting conditions, so up‑time and reproducible results increase; this makes the insert a rational choice where stable production and predictable tool changes matter.

Geometry and mounting that ensure repeatable clamping and accuracy

The trigon shape with an 80° included angle and a cylindrical hole enables positive, repeatable positioning in ISO‑compatible holders. With a 4.76 mm thickness, 0° relief and a 0.8 mm corner radius, the geometry provides a robust cutting edge that resists chipping while still allowing precise finishing passes. Compatibility with a holder is determined by form, relief angle, tolerance class, fastening method, size and thickness; therefore the insert is intended for use within an ISO system comprising a matching external holder or boring bar, a shim/clamping kit and the appropriate fixing screws.

Consistent chip control and economy in machining

The SM chipbreaker on this insert is tuned for secure chip formation across different depths of cut and feeds, reducing the likelihood of entangling or damaging swarf. Combined with the PVD surface treatment, the result is improved surface finish and longer intervals between tool changes. For operations that demand process reliability—short runs with frequent material changes or small‑diameter tooling—the balanced combination of chip control and wear resistance supports productive machining and predictable component quality.

FAQ

What materials is this insert designed for?
The WNMG080408‑SM AH725 insert is specified for machining steel and stainless steels; the PVD‑coated AH725 grade is selected for universal, out‑break resistant performance across these materials.

Which chipbreaker does the insert use and what is its effect?
This insert features the SM chipbreaker, which promotes controlled chip formation and reliable swarf evacuation, supporting consistent surface quality and reduced risk of chip interference.

What are the key geometric dimensions to consider when selecting a holder?
Key dimensions include the ISO size (08 / 080408), 4.76 mm thickness, 80° included angle, 0.8 mm corner radius and the cylindrical hole for secure mounting; holders must match these parameters for correct clamping.

How does the 0.8 mm corner radius influence machining?
A 0.8 mm radius increases edge strength and resistance to chipping, improving tool life for medium to finishing cuts while offering a compromise between robustness and achievable surface finish.

What system components are required to use this insert?
Use within an ISO system: a compatible external holder or boring bar, appropriate shim/clamping kit and replacement screws; compatibility is determined by form, relief, tolerance class, fastening, size and thickness.
