CCMT09T308-FM4 WSM20S indexable insert – Tiger·tec Silver coating, 0.8 mm radius | Walter Tools

A compact CCMT09T308-FM4 WSM20S indexable insert engineered for high‑performance turning and boring of rostfreier Stahl and heat‑resistant superalloys.

• Tiger·tec Silver coating for heat resistance
• Suitable for stainless steels and superalloys
• 0.8 mm corner radius for edge strength
• Rhombic 80° form with 7° clearance angle

Durable coating and longer tool life for demanding alloys

The combination of the Tiger·tec Silver coating and the WSM20S grade provides elevated thermal stability and wear resistance when machining tough materials. This results in prolonged tool life and fewer tool changes, which directly improves shop floor efficiency. The coated carbide substrate supports stable cutting edges under high temperatures and built‑up edge tendencies typical for rostfreier Stahl, while the specified tolerance class M ensures consistent geometry across production batches.

Geometry that improves chip formation and surface quality

The insert’s rhombic 80° profile and 7° clearance angle reduce cutting forces and support predictable chip flow. A 0.8 mm corner radius enhances edge strength for interrupted cuts and varying feed rates, aiding in consistent surface finish and dimensional accuracy. The FM4 chipbreaker is tuned to the material groups indicated, helping to break and evacuate chips reliably and lowering the risk of recutting or surface damage in medium to heavy turning operations.

Process reliability and productivity in serial manufacturing

Built for reliable performance in turning and boring applications, this indexable insert contributes to stable machining parameters and repeatable cycle times. The material designation S / M indicates suitability for heat‑resistant superalloys and rostfreie Stähle respectively, allowing process engineers to standardise tooling for mixed production runs. Reduced downtime from longer edge life and the predictable behaviour of the grade support higher overall productivity and lower unit cost over long production runs.

Practical application guidance and compatibility

The insert is compatible with standard CCMT toolholders and is designed for versatile use across turning and light boring operations. Selection of the correct cutting data—feed, speed and depth of cut—depends on the workpiece alloy and hardness; when machining rostfreier Stahl a focus on stable feeds and adaptable cutting speeds reduces heat concentration and promotes secure chip formation. For titanium and nickel‑base superalloys, the thermal benefits of the Tiger·tec Silver coating help maintain edge integrity under elevated cutting temperatures.
