VNMG160402‑FM5 WSM20S indexable turning insert, Tiger‑tec Silver (Walter Tools) — Rhombic 35°, 0.2 mm corner radius

A VNMG160402‑FM5 WSM20S indexable turning insert engineered for productive machining of rostfreier Stahl and heat‑resistant superalloys in demanding turning applications.

• Tiger‑tec Silver coating for wear resistance
• WSM20S grade for rostfreier Stahl and superalloys
• Rhombic 35° geometry for stable cutting
• 0.2 mm corner radius with 0° negative rake

Increased performance on difficult materials

The VNMG format insert combines a WSM20S grade with Tiger‑tec Silver technology to deliver reliable performance when machining challenging materials. The coated carbide composition is tailored to withstand thermal and mechanical stresses common with rostfreier Stahl and heat‑resistant superalloys, supporting stable chip formation and reduced edge wear. This results in longer service intervals and fewer insert changes during serial production, which improves overall process efficiency and component throughput.

Geometry that stabilises the cut and improves surface finish

The rhombic 35° shape with a 0.2 mm corner radius and 0° (negative) rake is designed for robustness in interrupted cuts and general turning operations. The FM5 chipbreaker supports controlled chip flow, reducing entanglements and helping maintain consistent surface quality. The insert’s geometry favours a balance between strength and cutting aggressiveness, enabling predictable behaviour under higher cutting forces and facilitating reproducible results across batches.

Practical benefits for shopfloor productivity

Adopting this insert in suitable toolholders provides tangible gains: fewer tool changes, steady dimensional accuracy and improved repeatability. The combination of grade and coating supports higher cutting volumes and contributes to cost‑effective machining cycles, especially where conventional grades struggle with heat and adhesion. For application guidance or if uncertainty exists about the best grade for a specific component, Metav Werkzeuge offers technical consultation to match cutting data and holder selection to the required production parameters.

FAQ

What materials is this insert suitable for?
The VNMG160402‑FM5 WSM20S insert is specified for rostfreier Stahl (ISO M) and for heat‑resistant superalloys or titanium (ISO S), offering reliable edge stability in these demanding groups.

How does the Tiger‑tec Silver coating improve tool life?
Tiger‑tec Silver on the WSM20S grade enhances thermal resistance and wear performance, helping the insert maintain a stable cutting edge and extend service life under elevated temperatures.

What does the FM5 chipbreaker do in practice?
The FM5 chipbreaker promotes controlled chip formation in turning of tough materials, reducing the risk of long, entangling chips and supporting consistent surface finish.

Is the geometry suitable for interrupted cuts?
Yes, the rhombic 35° shape combined with a 0° negative rake and a 0.2 mm corner radius provides robustness and shock resistance suitable for interrupted and general turning operations.

Which designation should be matched when selecting a toolholder?
Select a holder compatible with the VNMG160402‑FM5 form; the insert’s ISO designation and the SKU VNMG160402‑FM5‑WSM20S‑WALTER should be used to ensure correct fitment.
