WNMG060408-NMS WSM20S — Trigon 80° turning insert, Tiger·tec Silver coating | Walter Tools

A WNMG060408-NMS WSM20S turning indexable insert engineered for secure, high‑contact turning of rostfreie Stähle and heat‑resistant alloys in demanding production environments

• Tiger·tec Silver coating for edge stability
• Optimised for stainless and superalloys
• Trigon 80° geometry for secure clamping
• Corner radius 0.8 mm for consistent chips

Stable cutting for tough, heat‑generating materials

The coated carbide grade in the Tiger·tec Silver family provides a balanced combination of wear resistance and thermal stability, making it especially suitable for machining rostfreie Stähle (ISO group M) and heat‑resistant superalloys and titanium (ISO group S). The Trigon 80° insert shape increases the contact area with the toolholder, improving clamping security and reducing vibration in interrupted or heavy cuts. With a negative 0° free rake, the geometry prioritises edge robustness and predictable cutting forces, which supports consistent component tolerances and fewer scrap parts.

Better chip control and fewer process interruptions

Built with an NMS chipbreaker and a corner radius of 0.8 mm, this insert promotes controlled chip formation under challenging cut conditions. The chipbreaker geometry reduces the tendency for built‑up edge on sticky or work‑hardening alloys and ensures chips are broken and evacuated reliably. Improved chip behaviour not only shortens cycle times by lowering the risk of tool jams, but it also limits heat concentration at the cutting zone, extending effective cutting life and reducing the frequency of unplanned tool changes.

Integrates into production for higher uptime and repeatability

Tolerance class M and the standardised insert size and thickness enable fast replacement and repeatable positioning in common toolholders, so machining centres and lathes regain productivity quickly during service intervals. The coated cemented carbide composition and the Tiger·tec Silver technology mean longer effective tool life under high thermal load, which translates into fewer tool changes and lower overall operating hours per component. For process planners, this results in measurable gains in throughput and reduced rework rates without compromising surface quality.

FAQ

What materials is this insert optimised for?
The WNMG060408-NMS WSM20S insert is optimised for rostfreie Stähle (ISO group M) and heat‑resistant superalloys and titanium (ISO group S), combining thermal resistance and edge stability for these challenging materials.

How does the Trigon 80° shape affect clamping and wear?
Trigon 80° geometry increases the contact area in the toolholder, which improves clamping security and distributes cutting forces to reduce localised wear on the insert edge.

What role does the NMS chipbreaker play in production?
The NMS chipbreaker promotes predictable chip formation and evacuation, lowering the risk of built‑up edge and machine stoppages, which helps maintain continuous production.

Is the insert suitable for interrupted cuts or heavy roughing?
Yes. The negative 0° rake and robust grade make the insert well suited to interrupted cuts and heavier roughing operations where edge strength is essential.

How does the Tiger·tec Silver coating improve tool life?
Tiger·tec Silver coating enhances thermal stability and wear resistance, which reduces flank wear rates and extends tool life under high cutting temperatures and abrasive conditions.
