WNMG060408-FW5 WSM20S — Trigon 80° turning insert, Tiger‑tec Silver (Walter Tools)

The WNMG060408-FW5 WSM20S is a negative‑rake trigon turning insert designed for robust machining of rostfreier Stahl and heat‑resistant superalloys.

• Tiger‑tec Silver coated carbide grade WSM20S
• Trigon 80° insert with 0° negative rake
• FW5 chipbreaker for secure chip control
• Optimised for rostfreier Stahl and superalloys

Reliable cutting performance in difficult materials

The coated carbide WSM20S grade, part of the Tiger‑tec Silver series, is engineered for machining tough workpiece groups such as rostfreier Stahl and heat‑resistant superalloys. The combination of coating technology and substrate hardness ensures consistent edge stability under thermal and mechanical load. For production environments where chip formation and tool life directly affect throughput, this insert delivers measurable improvements in process reliability and reduces unscheduled tool changes.

Geometry that stabilises cutting and chip control

The Trigon 80° form with a 0° negative rake provides a robust cutting edge that resists deformation when turning demanding alloys. The FW5 chipbreaker is designed to produce short, controllable chips even under interrupted cuts, which simplifies chip evacuation and reduces the risk of surface defects. Negative rake geometry shifts forces into a more compressive regime at the cutting edge, which is beneficial when machining tough or gummy materials where conventional positive‑rake inserts would wear prematurely.

Coating and substrate benefits explained

A coated carbide construction delivers the balance between wear resistance and toughness required in challenging applications. The Tiger‑tec Silver coating improves thermal resistance and reduces built‑up edge tendency, while the substrate provides the mechanical support needed for repeated engagement with hard microstructures. This means longer intervals between indexings and more consistent part quality. For users unfamiliar with coating nomenclature: the coating primarily protects the cutting edge from heat and adhesion, extending usable tool life in high‑temperature cutting zones.

Practical application and selection advice

This insert is supplied in the standard WNMG form factor and is best utilised in stable toolholders suited to 80° trigon inserts. The 0.8 mm corner radius contributes to a secure edge for generating good surface finishes without compromising strength. Choose this grade when facing high cutting temperatures, interrupted cuts or workpieces that tend to form long, stringy chips. For series production where repeatability and stand‑time are key, the application benefits of this insert are particularly pronounced. The Walter Tools heritage ensures compatibility with common turning systems and industrial toolholding standards.

FAQ

Is this insert suitable for rostfreier Stahl (stainless steel)?
Yes. The WNMG060408‑FW5 WSM20S is optimised for rostfreier Stahl and provides secure chip formation and edge stability when machining these alloys.

How does the FW5 chipbreaker affect chip control?
The FW5 chipbreaker on this insert produces short, controllable chips, improving evacuation and reducing the likelihood of surface damage during turning operations.

What does the 0° negative rake mean for cutting forces?
A 0° negative rake increases compressive loading at the edge; this improves edge strength and resistance to chipping when machining tough materials with the WNMG060408‑FW5 WSM20S.

Can this insert be used for titanium and other superalloys?
Yes. The WSM20S grade is suitable for heat‑resistant superalloys and titanium‑group materials, offering enhanced thermal resistance and stable cutting behaviour.

Which toolholders are recommended for the Trigon 80° form?
Standard toolholders compatible with 80° trigon inserts are appropriate; ensure a rigid set‑up to capitalise on the insert’s edge stability and to maintain consistent surface quality.
