RCMT1204M0-RM4 WSM20S — turning insert, Tiger·tec Silver grade for rostfreier Stahl and superalloys by Walter Tools

The RCMT1204M0-RM4 WSM20S is a round turning insert designed for medium‑ to high‑demand machining of rostfreier Stahl and heat‑resistant superalloys, offering a thermally resistant coating and a chipbreaker tuned for stable cutting.

• Tiger·tec Silver coating for high process security
• Grade WSM20S optimised for rostfreier Stahl and superalloys
• Round RCMT form with 7° clearance angle
• Stable chip formation with RM4 chipbreaker

Consistent cutting performance for demanding materials

The combination of the Tiger·tec Silver coating and the WSM20S grade provides a coated carbide solution that is designed to resist thermal loading and maintain edge integrity when machining tough materials. The grade is formulated for applications in rostfreier Stahl and in heat‑resistant superalloys and titanium alloys, where heat generation and edge wear are primary concerns. As a result, machining operations benefit from more consistent tool life and repeatable surface finish, which supports cycle‑time reduction and fewer tool changes in production environments.

Geometry engineered for control and surface quality

The insert’s RCMT geometry, a round insert with an inscribed circle of 12 mm and a plate thickness of 4 mm, provides strength at the cutting edge and flexibility in feed direction. The 7° clearance angle reduces rubbing while preserving support behind the cutting edge, enabling secure chip formation. The RM4 chipbreaker is tuned for reliable evacuation and short, controllable chips in medium feeds, simplifying swarf management and lowering the risk of built‑up edge. These characteristics make the insert suitable for semi‑finishing and finishing passes depending on the chosen toolholder and cutting data.

Practical benefits for shopfloor productivity

Specifically developed for challenging alloys, the insert supports stable machining where thermal resistance and edge stability matter most. The WSM20S grade, belonging to the Tiger·tec Silver family, emphasises process security and consistent performance across batches. Selection of this insert can reduce unplanned downtime and improve first‑pass yields. For grade and geometry matching to machine capability and component tolerances, Metav Werkzeuge’s technical advisors can provide data‑driven recommendations, including suggested holder types and parameter windows based on the workpiece material and cycle requirements.

FAQ

Which materials is this insert intended for?
The RCMT1204M0‑RM4 WSM20S insert is intended primarily for rostfreier Stahl and for heat‑resistant superalloys/titanium (ISO groups M and S), where thermal stability and edge resilience are required.

What are the key geometric dimensions of the insert?
The insert has an inscribed circle of 12 mm and a thickness of 4 mm; it is a round RCMT form with a 7° clearance angle and an RM4 chipbreaker.

What advantages does the Tiger·tec Silver series provide?
Tiger·tec Silver offers enhanced thermal resistance and wear properties for coated carbide grades, resulting in improved process security and longer life under thermally demanding turning conditions.

Is this insert suitable for finishing and semi‑finishing?
Yes, depending on the chosen toolholder geometry and cutting data, the insert can be used for both semi‑finishing and finishing operations thanks to its stable edge and chip control characteristics.

How does the RM4 chipbreaker affect chip behaviour?
The RM4 chipbreaker is designed to produce short, controlled chips in medium feed ranges, reducing swarf entanglement and improving evacuation in continuous turning operations.
