SNMG120412-RM5 WSM20S — Tiger·tec Silver square 90° turning insert by Walter Tools

SNMG120412-RM5 WSM20S is a coated, square 90° turning insert designed for heavy and challenging machining of stainless steels and heat‑resistant superalloys

• Tiger·tec Silver coating, WSM20S grade
• Optimised RM5 chipbreaker for heavy cuts
• Square 90° insert with 1.2 corner radius
• Negative 0° relief for secure insert seat

Consistent edge life and process security for demanding materials

The combination of Tiger·tec Silver technology and the WSM20S carbide grade provides a well‑balanced performance profile for machining tough-to-cut materials. The applied coating improves heat resistance and wear behaviour, which leads to stable chip formation and prolonged cutting edge life. This results in fewer tool changes and higher machine uptime, translating into measurable improvements in process reliability and productivity when working with stainless steels and high‑temperature alloys.

Geometry tailored for robust turning and repeatable results

A square 90° shape with a 1.2 corner radius and 0° relief gives a secure seating position and a strong cutting edge capable of absorbing higher cutting forces. The RM5 chipbreaker controls chip flow during heavy engagement, reducing the risk of built‑up edge on sticky materials. Together, the geometry and chipformer support predictable behaviour under load, which simplifies process planning and minimises scrap in series production.

Practical advantages in workshop and production use

The insert’s specification supports stable performance in roughing and semi‑finishing operations on materials classified as M (stainless steels) and S (heat‑resistant superalloys and titanium). Because the grade and coating are optimised for thermal and mechanical load, fewer tool indexings are required and component tolerances can be met more consistently. This balance of wear resistance and edge stability contributes to cost‑effective machining over the life of the tool.

Application guidance and compatibility

Intended for use in standard indexable tool holders that accept SNMG style inserts, the item is suitable where high thermal loads and adhesive tendencies present a machining challenge. Selection of cutting parameters should consider workpiece material, toolholder rigidity and machine capability; the insert’s design reduces the risk of premature edge failure under heavy cut regimes. For detailed machining parameter recommendations and holder compatibility, Metav Werkzeuge can provide tailored support.
