TCMT090204-RM4 WSM20S — Turning indexable insert (triangle 60°, 7° relief), Tiger‑tec Silver, Walter Tools

The TCMT090204-RM4 WSM20S is a coated carbide triangular insert designed for finishing and semi‑finishing turning of stainless steel and heat‑resistant superalloys, combining a robust cutting grade with a reliable chip control geometry

• Tiger‑tec Silver for heat resistance and wear control
• RM4 chipbreaker for stable chip formation
• Triangle 60° for versatile turning applications
• 0.4 mm corner radius for enhanced edge strength

Consistent performance on difficult materials

The WSM20S grade, produced within the Tiger‑tec Silver range, is engineered for machining materials that tend to generate heat and sticky chips. By combining a coated carbide substrate with a tailored coating system, the insert supports stable chip formation and extended tool life under challenging conditions. This yields fewer interruptions in the machining cycle and more predictable tool‑change intervals, which benefits production planning and reduces unplanned downtime.

Geometry and edge design for process reliability

The triangle 60° form and a 7° relief angle deliver a balance between cutting strength and accessibility in tight radii or profile turns. The RM4 chipbreaker is optimised for controlled chip flow on stainless steel and superalloys, reducing the risk of built‑up edge and improving surface integrity. A 0.4 mm corner radius strengthens the cutting edge against mechanical and thermal shock, providing repeatable results in series production.

Practical advantages in the machining sequence

Using this insert in a stable toolholder arrangement leads to predictable metal removal and consistent surface finish in finishing and semi‑finishing operations. The combination of grade and chipbreaker helps to maintain edge stability across varying feed rates and depths of cut, which supports higher process security and consistent part quality. Where frequent tool changes are costly, the insert’s wear characteristics contribute to overall productivity gains.

Compatibility and handling notes

The indexable insert is supplied in the TCMT090204 format and fits holders designed for triangular 60° inserts with the corresponding seat. Material designation S / M indicates suitability for heat‑resistant superalloys and stainless steel; adjust cutting parameters to the specific workpiece and machine rigidity. For best results, pair the insert with a rigid clamping system and review coolant strategy to support chip evacuation and thermal control.
