WCMT06T308-MM4 WSM20S Trigon 80° turning insert — Tiger·tec Silver, 0.8 mm corner radius (Walter Tools)

A WCMT06T308-MM4 WSM20S indexable turning insert engineered for heavy-duty machining of stainless steel and high-temperature alloys in demanding production environments

• Tiger·tec Silver coating performance
• Optimised MM4 chipformer for stability
• Trigon 80° geometry for versatile cutting
• Suited to stainless steel and superalloys

Reliable cutting performance for difficult materials

The combination of the WSM20S grade and the Tiger·tec Silver coating provides enhanced wear resistance and thermal stability, specifically designed for machining stainless steel and heat-resistant superalloys. The insert’s coating technology reduces flank wear and supports consistent cutting-edge life under elevated temperatures. By choosing this indexable insert, workshops gain predictable tool life and reduced changeover frequency, which contributes to higher overall productivity on difficult-to-machine components.

Secure chip control and edge stability during turning

Equipped with the MM4 chipformer and a 0.8 mm radius, the geometry promotes reliable chip formation even when cutting materials that tend to work-harden or form long, stringy chips. This results in fewer interruptions and more consistent surface finishes. The Trigon 80° form gives favourable cutting edge exposure for both finishing and light machining, while the T3 thickness supports rigidity at higher cutting forces. Clear chip evacuation lowers the risk of built-up edge and extends the effective life of the cutting edge.

Designed to support reproducible, shop-floor results

The insert’s tolerance class M and standard ISO designation ensure compatibility with common toolholders and predictable positional repeatability during index changes. The robust design aims to reduce variability between tool changes and operators, making it suitable for serial production where consistency is required. This practical reliability encourages shorter set-up times and contributes to a smoother production flow when machining parts in stainless steel or titanium-containing alloys.

Practical benefits for process planning and procurement

Because the grade is targeted at both stainless steel (M) and superalloys/titanium (S), tool selection becomes more straightforward for mixed-material production runs. Planners can rely on one insert geometry and coating system for a wider material range, simplifying stock keeping. The insert’s measured characteristics — such as 0.8 mm corner radius, 7° relief angle, and Trigon 80° form — support engineering calculations for cutting data and help to estimate tool life under specific feed and speed regimes.
