CCMT09T304-RM4 WSM20S – Turning insert, Tiger·tec Silver coating, RM4 chipbreaker (Walter Tools)

The CCMT09T304-RM4 WSM20S is a rhombic 80° indexable turning insert designed for heavy machining of rostfreier Stahl and heat‑resistant alloys, combining a wear‑resistant grade with a geometry for secure cutting action

• Tiger·tec Silver coated carbide grade WSM20S
• Optimised for rostfreier Stahl and superalloys
• RM4 chipbreaker for consistent chip control
• Rhombic 80° geometry with 7° relief

Consistent performance in demanding materials

The combination of the WSM20S grade and the Tiger·tec Silver coating delivers improved edge stability under thermal and mechanical stress. Intended for tough applications involving rostfreier Stahl and heat‑resistant superalloys (ISO groups M and S), the insert’s coated carbide composition helps to limit built‑up edge and to maintain cutting capability at elevated temperatures. For shops aiming to reduce insert changes, this results in fewer interruptions and more predictable component quality.

Reliable chip control and process security

Built around the RM4 chipbreaker, the geometry promotes short, controllable chips for interrupted or continuous turning. The rhombic 80° shape and 7° relief balance cutting edge engagement and tool strength, while the 0.4 mm corner radius supports improved surface finish and reduced edge chipping. These parameters combine to provide secure chip control and steady cutting forces, which in turn simplifies process planning and results in consistent workpiece quality.

Efficient integration and handling for productive machining

The insert’s T3 thickness and CCMT format ensure compatibility with standard indexable turning toolholders, enabling quick index changes and repeatable setup. Marked by a coated grade developed for difficult‑to‑cut materials, the design supports higher material removal rates where tool life predictability is essential. For process planning, the insert is a practical choice when machining rostfreier Stahl and superalloys; Metav Werkzeuge can advise on holder selection and cutting parameters to match production goals.
