WCMT030202-RM4 WSM20S Trigon 80° indexable insert for turning and drilling applications (Walter Tools)

WCMT030202-RM4 WSM20S is a versatile indexable insert designed for demanding turning and drilling tasks in stainless steels and superalloys, combining a resilient grade with a geometry tuned for stability and surface quality.

• Tiger·tec Silver coating for high wear resistance
• Geometry Trigon 80° for stable cutting edge
• 7° clearance angle with 0.2 mm corner radius
• RM4 chipbreaker for controlled chip formation

Reliability when machining tough alloys

The WSM20S grade, part of the Tiger·tec Silver family, is formulated for applications in stainless steels and heat‑resistant superalloys. This composition supports stable chip formation and protects the cutting edge under elevated temperatures, which reduces the risk of built‑up edge and frequent interruptions. The result is a more predictable process and fewer re‑works in serial production environments.

Geometry and chip control for consistent surfaces

With a Trigon 80° profile and the RM4 chipbreaker, the insert provides controlled chip breakage and a robust cutting edge for medium to finishing cuts. The specified 7° clearance angle and the 0.2 mm corner radius contribute to a balance between edge strength and surface finish, helping to maintain dimensional accuracy and homogeneity of the machined surface across batches.

Productivity gains through extended tool life

The coated WSM20S grade extends tool life and enables higher uninterrupted runtime compared with uncoated options when processing difficult materials. Improved wear resistance and edge stability translate into fewer tool changes and less unplanned downtime, supporting higher overall equipment efficiency and a lower cost per manufactured part over the long run.

Practical selection and integration notes

The insert is supplied in the standard size and thickness coding suitable for conventional tool holders (size code 03, thickness code 02) and is compatible with turning and boring/drilling tool systems designed for triangular inserts. For reliable results, combine the insert with appropriate coolant strategies and select feeds and depths of cut based on workpiece material and machine rigidity; trial cuts are recommended for new combinations.
