SCMT09T304-RM4 WSM20S indexable insert — square 90° insert for stainless and superalloys, Walter Tools

SCMT09T304-RM4 WSM20S is a multi‑purpose indexable insert designed for demanding applications in heat‑resistant alloys and rostfreier Stahl, combining a robust geometry with advanced coating technology

• Tiger‑tec Silver coating for thermal stability
• WSM20S grade for tough materials and titanium
• RM4 chipbreaker for secure chip control
• 0.4 mm corner radius with 7° clearance angle

Consistent performance on rostfreier Stahl and superalloys

The combination of the WSM20S carbide grade and Tiger‑tec Silver coating is engineered for materials that generate high cutting temperatures and tend to form built‑up edge. With a focus on thermal resistance and edge stability, this insert supports a controlled chip flow and reduces the risk of rapid flank wear. The specified grade targets both rostfreier Stahl and heat‑resistant superalloys, offering manufacturers higher process reliability when machining difficult alloys.

Geometry and chip control that reduce rework

The RM4 chipbreaker and the 0.4 mm corner radius work together to produce short, manageable chips and to distribute cutting forces across a stable cutting edge. The square 90° form delivers robust support in interrupted cuts and provides versatile orientation options in common toolholders. The 7° clearance angle helps maintain a secure cutting geometry that reduces rubbing and promotes repeatable surface quality, translating into fewer corrective operations and increased throughput.

Integration into productive workflows

As a coated carbide indexable insert with the proven Tiger‑tec Silver technology, this plate supports predictable tool life and consistent results across shifts. The insert’s dimensions and tolerance class facilitate rapid indexing and reliable seating in the toolholder, contributing to shorter set‑up times and steady production rates. For applications where material variation and thermal load are critical, the insert offers a balance of wear resistance and edge stability to help sustain productive machining cycles.
