VNMG160408-PS AH6225 — VNMG 160408 turning insert for turning, PVD-coated carbide, 0.8 mm radius (Tungaloy)

The VNMG160408-PS AH6225 is an ISO‑standard indexable turning insert engineered for external and internal turning operations, offering a balance of edge sharpness and stability for medium machining of rostfreier Stahl.

• VNMG form ISO 160408 rhombic insert
• PVD-coated carbide grade AH6225
• 0.8 mm corner radius for versatile cuts
• Cylindrical hole for secure clamping

Consistent cutting performance for medium-duty turning

The insert is manufactured from carbide with a PVD-coated carbide surface and the AH6225 grade, which targets machining of rostfreier Stahl under varying conditions. This combination yields a sharp, stable cutting edge that tolerates typical process fluctuations, making it suitable for medium cutting depths and intermittent operations. The integrated PS chipbreaker supports predictable chip formation, reducing cycle interruptions and assisting in maintaining consistent surface quality during long production runs.

Clear guidance on fit, geometry and holder compatibility

As an ISO-standard plate, compatibility with the toolholder is determined by the insert form, tolerance class, fastening method, size and thickness. The rhombic profile with a 0.8 mm corner radius and a cylindrical hole ensures secure clamping and defined orientation. A nominal 0° clearance and a 35° lead angle influence rake and contact behaviour; such geometry requires a matched holder profile to achieve the intended cutting angles and stable tool engagement. These measurable parameters enable straightforward selection of the correct clamping system and reduce setup variability.

Coating, chip control and productivity advantages

The PVD-coated surface enhances wear resistance and supports longer intervals between index changes, while the PS chipbreaker is tuned for controlled chips when machining rostfreier Stahl. Together these features promote enhanced tool life and reliable surface finishes without aggressive process tuning. In practice this means fewer unscheduled tool changes, reduced scrap risk and a stable machining rhythm — all contributing to improved throughput and predictable manufacturing costs.

Practical application notes and selection tips

Designed for both external and internal turning, the insert performs best when the chipbreaker and grade are matched to workpiece material, depth of cut and fixture stiffness. For unstable setups or heavy interruptions, consider softer cutting parameters or alternative chip control strategies to protect the cutting edge. For straightforward setups and medium-duty cuts the plate offers a good compromise between cutting performance and robustness.

FAQ

What materials is the insert suitable for? The insert grade AH6225 and its PVD-coated carbide construction are optimised for rostfreier Stahl and offer a broad coverage for common stainless applications.

How does the PS chipbreaker affect machining? The PS chipbreaker on the VNMG160408-PS AH6225 promotes controlled chip formation, which reduces interruptions and helps maintain consistent surface finish during turning.

Which holders are compatible with this ISO insert? Compatibility depends on the holder's form, tolerance class, fastening type, size and thickness; the rhombic shape and cylindrical hole require a matched holder designed for ISO 160408 plates.

What does the 0° clearance angle imply for set-up? A nominal 0° clearance indicates the plate geometry requires the correct holder rake and clearance geometry to avoid rubbing; selection of a suitable holder is essential for effective cutting action.

Is this an original Tungaloy product and where to buy? This is an original Tungaloy indexable insert (VNMG160408-PS AH6225, SKU 6947469-Tungaloy); Metav Werkzeuge can supply genuine parts and advise on process integration.
