RCMT10T3M0-FM4 WSM20S – Indexable turning insert for stainless steel and superalloys (Walter Tools)

The RCMT10T3M0-FM4 WSM20S is a round indexable turning insert engineered for demanding applications, combining a coated carbide grade from the Tiger·tec Silver series with an FM4 chipbreaker to support secure chip formation in stainless steel and titanium‑basis superalloys.

• FM4 chipbreaker for stable chip control
• 7° clearance, round 10 mm plate, T3 thickness

Maximum process reliability for tough materials

The Tiger·tec Silver coating paired with the WSM20S carbide grade provides elevated heat resistance and a reliably stable cutting edge when machining difficult materials. Designed to address the ISO groups M and S, this grade helps to control tendencies such as adhesive wear and built‑up edge that occur with stainless steel and heat‑resistant superalloys. As a result, the insert contributes to consistent component quality and reduced process variability, supporting predictable cycle times and improved production uptime.

Predictable chip formation and secure edge life

Thanks to the FM4 chipbreaker and its round plate form, the geometry promotes controlled chips and reduces the risk of entangling or long stringy chips in interrupted cuts. The 7° clearance together with the T3 plate thickness supports edge stability under higher mechanical and thermal loads, which lowers the probability of premature edge failure. These geometry features translate into fewer tool changes and steadier surface finish — a practical advantage for series production and critical components.

Productivity gains and economical machining

The combination of a coated carbide grade and a dedicated chipbreaker focuses on maintaining cutting performance over longer tool life. The insert’s behaviour under thermal stress and its stable edge retention help to decrease machining costs per part through extended intervals between indexing. Consistent surface quality and repeatable tool life are particularly valuable when processing high‑value components where rework or scrap would have a significant economic impact.

Selection guidance for secure integration

The round 10 mm plate form and the RCMT geometry suit a range of turning holders that accept this family; the WSM20S grade is especially recommended where machining of stainless steel or titanium alloys is frequent. For an accurate match of cutting parameters — feeds, speeds and depth of cut — and to confirm the best holder‑insert pairing for a given machine and workpiece, refer to Metav Werkzeuge’s technical advisory. Practical cutting data and trial recommendations help to unlock the insert’s full potential in specific production environments.

FAQ

Which materials are suitable for this insert?
The RCMT10T3M0-FM4 WSM20S insert is developed for stainless steel (ISO group M) and heat‑resistant superalloys/titanium (ISO group S), where the WSM20S grade supports secure chip formation and edge stability.

What are the main benefits of the Tiger·tec Silver coating?
The Tiger·tec Silver coating on the WSM20S grade enhances thermal resistance and reduces wear speed, which helps to maintain cutting performance and surface finish during extended runs.

How does the FM4 chipbreaker affect machining?
The FM4 chipbreaker provides controlled chip segmentation and evacuation, improving process security and reducing the risk of built‑up edge when turning difficult materials.

What does the 7° clearance mean in practice?
The 7° clearance angle contributes to cutting edge stability and reduces rubbing at the flank face, supporting longer edge life under the thermal and mechanical demands of stainless steel and superalloys.

Is this insert suitable for automated production environments?
Yes, the combination of a coated carbide grade, the FM4 chipbreaker and stable geometry makes the insert well suited to automated and series production where repeatable tool life and consistent part quality are required.
