VCMT160408-RM4 WSM20S — Turning insert, Tiger‑tec Silver grade, for stainless steel & superalloys (Walter Tools)

VCMT160408-RM4 WSM20S is an indexable turning insert optimised for machining stainless steel and heat‑resistant superalloys, combining a thermally resistant coating with a geometry tuned for stable cutting.

• Tiger‑tec Silver coating for enhanced wear resistance
• WSM20S grade optimised for stainless steel and superalloys
• Rhombic 35° form with 0.8 mm corner radius
• 7° clearance angle for consistent edge stability

Consistent performance on difficult-to-machine alloys

The combination of the Tiger‑tec Silver coating and the WSM20S carbide grade is engineered to resist thermal and mechanical wear encountered when machining stainless steel and superalloys. The coating reduces adhesion and built‑up edge while the grade supports a stable cutting edge at elevated temperatures. For production environments where repeatable tool life matters, this insert reduces unplanned interruptions and contributes to more consistent cycle times — a clear rational advantage for mixed‑batch or serial turning operations.

Geometry that improves surface finish and chip control

A rhombic 35° insert form with a 0.8 mm corner radius delivers a balance between robustness and the ability to achieve good surface finish in finishing and medium‑depth turning. The RM4 chipbreaker is designed to promote controllable chip formation and smooth evacuation, which is particularly important when removing long, stringy chips from ductile alloys. The 7° clearance angle supports stable contact between the tool and workpiece, helping to maintain dimensional accuracy and reduce vibration during cuts.

Productivity gains and shop-floor compatibility

The VCMT geometry is widely supported by standard toolholders, enabling quick indexable insert changes and straightforward tool management. The combination of predictable wear behaviour and the Tiger‑tec Silver system means fewer tool changes and higher uptime, leading to improved productivity and lower machining cost per component. As a Walter Tools product, the insert benefits from a portfolio approach that simplifies grade selection for specific materials and cutting conditions, supporting process optimisation across a range of turning applications.

FAQ

Which materials are recommended for these inserts?
The VCMT160408-RM4 WSM20S insert is specified for stainless steel (M) and for heat‑resistant superalloys/titanium (S), where thermal resistance and edge stability are critical.

What does the RM4 chipbreaker achieve in practice?
The RM4 chipbreaker promotes short, controlled chips and reliable evacuation, improving surface finish and reducing the risk of chip entanglement in applications using this Walter Tools turning insert.

Which machining operations suit the rhombic 35° form?
The 35° rhombic form is versatile for general turning, especially where a compromise between reach and strength is needed; it supports finishing and medium cutting with consistent results.

How does the Tiger‑tec Silver coating affect tool life?
The Tiger‑tec Silver coating reduces heat‑related wear and adhesion tendencies, which in turn extends tool life and delivers more stable cutting performance in demanding materials.
