TNMG160408-FM5 WSM20S indexable turning insert — Tiger·tec Silver, FM5 chipbreaker (Walter Tools)

A TNMG160408-FM5 WSM20S indexable turning insert designed for secure chip formation and stable edge life in the machining of stainless steels and superalloys

• Tiger·tec Silver coated carbide
• Grade WSM20S for M and S materials
• FM5 chipbreaker for controlled chips
• Triangle 60° form, 0.8 mm corner radius

Reliable machining of stainless steels and superalloys that reduces rework

The coated carbide composition in the Tiger·tec Silver series provides a balanced combination of thermal resistance and mechanical strength, which translates into secure chip formation when cutting tough materials. The WSM20S grade is optimised for the specific challenges of stainless steels and heat-resistant superalloys (ISO group M and S): toughness to avoid chipping, and a coating to withstand elevated cutting temperatures. As a result, the tool life is extended and the frequency of tool changes is reduced, supporting uninterrupted production cycles.

Consistent surface quality and stable cutting edge for repeatable results

With the FM5 chipbreaker and a 0.8 mm corner radius, the insert delivers steady chip control and a reliable cutting edge geometry. The triangle 60° form ensures versatile mounting positions, allowing effective use of each corner while maintaining dimensional consistency. This design contributes directly to process stability and predictable surface finish, which is essential for serial production and high-accuracy components.

Efficiency gains through predictable performance and easy integration

The insert’s negative 0° rake (negative geometry) and the proven Tiger·tec Silver coating work together to reduce the risk of built-up edge and thermal damage in demanding operations. The result is a lower reject rate and fewer in-process interruptions. The insert is compatible with common toolholders for triangular inserts, enabling straightforward replacement and quick setup in existing turning stations — a pragmatic choice for workshops seeking to improve throughput without extensive retooling.

Practical application advice to improve cutting results

For best performance with stainless steels and superalloys, moderate cutting speeds combined with appropriate feed and coolant strategies help to exploit the coating’s thermal resistance and the chipbreaker’s evacuation characteristics. The insert’s specification—TNMG160408-FM5 WSM20S, Tiger·tec Silver—indicates suitability for operations where both edge stability and heat management are critical. Where in doubt about process parameters or clamping, Metav Werkzeuge can provide tailored recommendations for particular workpiece alloys and machine conditions.
