WNMG080408-MU5 WSM20S — Trigon 80° indexable turning insert with Tiger·tec Silver (Walter Tools)

A WNMG080408-MU5 WSM20S indexable turning insert optimised for reliable machining of stainless steels and heat‑resistant superalloys in demanding turning operations

• Tiger·tec Silver coating for heat resistance and wear control
• Optimised MU5 chipformer for stable chips
• Trigon 80° geometry for secure clamping
• 0.8 mm corner radius for robust edge protection

Maximise productive cutting with a heat‑resistant grade

The combination of the Tiger·tec Silver coating and the WSM20S grade provides a balance between thermal resistance and mechanical toughness, helping to maintain edge integrity during elevated cutting temperatures. This turning solution reduces the risk of built‑up edge when working with stainless steels, while the coated carbide substrate supports steady performance when cutting tough, heat‑resistant alloys. The result is improved tool life and fewer index changes, supporting higher component throughput and predictable cycle times.

Predictable chip control and surface quality under load

The MU5 chipformer is engineered to produce controlled chip segments in interrupted or continuous cuts, which reduces the likelihood of entanglement and eases chip evacuation. Controlled chip formation contributes directly to a consistent surface finish and reduces secondary operations. For parts where surface integrity matters, the pairing of the chipbreaker geometry and the coating technology yields repeatable results and helps maintain process stability in serial production.

Geometry and edge robustness for secure operations

The Trigon 80° insert form combined with a 0.8 mm corner radius gives a secure seating in the toolholder and a resistance to mechanical shock at entry and exit. The insert’s 0° negative rake promotes a strong cutting edge for heavier roughing passes and supports higher feed rates where required. Together, these geometric choices mean fewer unexpected interruptions and a robust response to varying workpiece conditions, particularly in clamping‑sensitive turning centres.

Application range and handling advice for workshop integration

Designed for the material groups S and M, this insert is suitable where heat‑resistant superalloys and stainless steels are predominant. Selection of cutting data should consider the coated carbide’s thermal benefits: higher cutting speeds are possible compared with uncoated grades, while feeds and depths should be adjusted to the component geometry and machine rigidity. Where uncertainty exists about parameter settings, Metav Werkzeuge’s consultants can recommend starting values tailored to the machine, material and required surface quality.
