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.

SCMT120408-RP4 WPP10G WPP10G Wendeplatten - Walter Tools
Benefit from the combination of a durable Tiger·tec Gold coating, the wear-resistant WPP10G grade and a precise 0.8 mm corner radius for stable, high-productivity machining of steel components. Order the inserts directly via Metav Werkzeuge or consult the team for application support. SCMT120408-RP4 WPP10G indexable insert — turning and boring insert by Walter Tools, Tiger·tec Gold, 0.8 mm radius The SCMT120408-RP4 WPP10G is an indexable insert designed for reliable turning and boring of steel, combining a coated carbide grade with a chipbreaker optimised for stable chip control in continuous and interrupted cuts Tiger·tec Gold coating for longer tool life Precision square 90° geometry for consistency 7° relief angle for stable cutting performance Grade WPP10G optimised for steel machining Higher cutting reliability thanks to modern coating technology The combination of the Tiger·tec Gold technology and the WPP10G carbide class provides a balanced performance profile for machining steel. The advanced coating reduces flank wear and improves thermal stability during heavy or elevated-speed cutting, which translates into longer tool life and fewer insert changes. For production environments this means more predictable tool cycles and reduced process interruptions, supporting efficient throughput and consistent part quality. Geometry and edge preparation that enhance surface finish The square 90° insert form with a 0.8 mm corner radius and a 7° relief angle is intended to deliver stable cutting behaviour and repeatable component surfaces. The moderate corner radius balances edge strength and surface quality, enabling reliable performance on a range of turning and boring operations. The insert thickness of 4 mm adds rigidity at the cutting edge, reducing vibration and helping to maintain dimensional accuracy in short and medium-length turning cycles. Tailored for steel with a chipbreaker optimised for chips Engineered primarily for steel applications (material group P), the insert features the RP4 chipbreaker which is tuned to promote stable chip formation and evacuation in typical steel grades. That results in fewer built-up edges, better tool life and a reduced risk of surface damage. The specification supports a wide spread of operational needs from general turning to more demanding interrupted cuts, offering flexibility without compromising productivity.
