SCMT120408-RM4 WSM30S indexable insert — Tiger·tec Silver coating, RM4 chipbreaker (Walter Tools)

SCMT120408-RM4 WSM30S is a square 90° indexable insert for drilling/boring and turning applications, designed for demanding work on stainless steel and heat‑resistant superalloys

• Tiger·tec Silver coating for edge stability
• RM4 chipbreaker for controlled chip formation
• 7° clearance angle for consistent engagement
• Square 90° insert with 0.8 mm corner radius

Consistent performance on difficult materials

The coated carbide composition of this insert, supplied in the Tiger·tec Silver series, delivers thermal resistance and edge stability when machining tough-to-cut alloys. The WSM30S grade is formulated for stainless steel and high-temperature superalloys or titanium, supporting secure chip formation under elevated cutting temperatures. By combining a heat-resistant coating with a geometry tuned for stability, the insert reduces edge deterioration and helps maintain cutting parameters for longer tool life, which improves process reliability and predictable part quality.

Geometry and chip control that boost productivity

The RM4 chipbreaker and the square 90° plate geometry provide reproducible chip shapes and evacuation, reducing recutting and downtime. A 7° clearance angle minimises friction at the flank face while the 0.8 mm corner radius balances strength and the capacity for reliable corner turning or bore finishing. These geometric choices translate into tangible productivity benefits: more consistent surface finishes and fewer interrupted cycles for edge dressing, especially when working with sluggish heat conduction typical of stainless steel or superalloys.

Integration into the machining process and handling

Designed as an insert for versatile turning and boring toolholders, the SCMT configuration allows simple indexation and economical tool management. The designation SCMT120408-RM4 WSM30S denotes the plate geometry and chipbreaker combination, supporting quick identification in a toolroom environment. For workshops seeking reduced variability, the coated grade and defined tolerance class deliver repeatable results across batches. For additional process guidance, Metav Werkzeuge provides application recommendations and machining data to align feed and speed with component requirements.
