WNMG080412-MU5 WSM20S turning insert — Tiger‑tec Silver, for rostfreier Stahl and superalloys | Walter Tools

The WNMG080412-MU5 WSM20S is a Trigon 80° turning insert engineered for heavy‑duty and difficult‑to‑machine applications, offering a balance of edge stability and controlled chip formation for rostfreier Stahl and heat‑resistant superalloys.

• Tiger‑tec Silver coated carbide grade
• Designed for rostfreier Stahl and superalloys
• Trigon 80° profile for robust cutting
• MU5 chipbreaker for controlled chip formation

Higher process reliability in heavy turning operations

The coated carbide WSM20S grade from the Tiger‑tec Silver family delivers a wear‑resistant cutting zone that is specifically optimised for ductile, strain‑hardening materials. Its design reduces edge build‑up and thermal degradation under high machining temperatures, which translates into longer tool life and fewer unscheduled insert changes. The combination of a robust coating and a grade tuned for stability ensures consistent component quality in serial production, supporting predictable cycle times and less rework.

Improved surface finish through controlled chip formation

A dedicated MU5 chipbreaker offers reliable chip control even when machining sticky or work‑hardening alloys. Controlled chip formation minimises interruptions and reduces the risk of surface damage, resulting in an improved finish and less manual cleaning. Because the chipbreaker geometry is matched to the insert form, the insert supports steady material evacuation and stable cutting conditions, which is crucial when processing rostfreier Stahl where heat and adhesion commonly affect surface integrity.

Robust geometry that withstands demanding cuts

The Trigon 80° form and a 1.2 mm corner radius provide mechanical strength at the cutting edge, making the insert suitable for interrupted cuts or heavy cross‑section removal. The 0° (negativ) relief angle increases edge support and resists chipping under heavy engagement, enabling more aggressive feeds and depths of cut without sacrificing edge security. These geometric choices favour production environments where durability and repeatability are required over extended tool campaigns.

Compatibility, handling and production benefits

Tolerance class M and the standardised insert dimensions ensure straightforward mounting and interchangeability in common toolholders. The grade is specified for material groups S and M, meaning it is applicable to heat‑resistant superalloys and rostfreier Stahl; this reduces the need for multiple tool families and simplifies inventory. Clear grade identification and a consistent coating behaviour support predictable process set‑up and make this insert a practical option for job shops and production lines aiming to streamline turning operations.
