SCMT09T308-RM4 WSM20S — Boring/turning indexable insert, RM4 chipbreaker, Tiger·tec Silver, Walter Tools
The SCMT09T308-RM4 WSM20S is a square, 90° indexable insert engineered for heavy-duty turning and boring of stainless steel and heat-resistant superalloys in demanding production environments.
- Tiger·tec Silver coating for edge stability
- Optimised RM4 chipbreaker for secure chips
- 7° clearance angle for reliable cutting
- Square 90° form with 0.8 mm nose radius
Consistent chip control for demanding materials
The combination of the RM4 chipbreaker and the WSM20S grade (Tiger·tec Silver technology) promotes stable chip formation when machining tough alloys. As an indexable insert designed for heavy-duty use, the geometry supports uninterrupted chip flow and reduces the risk of built-up edge. This results in fewer interruptions on the shop floor and a steadier surface finish when working with stainless steel and heat-resistant superalloys.
Stable cutting edges and extended tool life
The coated carbide composition in WSM20S emphasises thermal resistance and edge stability under high cutting temperatures. The Tiger·tec Silver coating improves wear resistance and helps preserve the cutting edge over extended cycles, which contributes to process security and predictable tool-change intervals. The 7° clearance angle reduces flank rubbing and supports reliable contact conditions at the cutting zone.
Versatile geometry for accurate turning and boring
The square 90° form combined with a 0.8 mm nose radius and plate thickness T3 delivers a balance between strength and surface quality. This geometry allows secure axial engagement in boring bars or toolholders and provides a consistent contact profile for shoulder turning and external facing. The result is reproducible dimensional control and good edge robustness without sacrificing workpiece finish.
Practical integration and selection guidance
When integrating the insert into a tooling system, match the insert designation and holder geometry for correct seating and clamping. The SCMT09T308-RM4 WSM20S maintains compatibility with standard indexable turning and boring toolholders that accept square 90° inserts; selection should favour holders that ensure minimal overhang to exploit the grade’s thermal and mechanical advantages. For process optimisation, pair the insert with cutting parameters suited to stainless steel and high-temperature alloys to benefit from the stable chip control and enhanced edge life.
