CCMT120408‑MW4 WSM20S turning insert by Walter Tools — Tiger‑tec Silver for stainless steel and heat‑resistant superalloys

The CCMT120408‑MW4 WSM20S is a rhombic 80° indexable turning insert engineered for machining stainless steels and heat‑resistant superalloys, combining a coated‑carbide grade with a stable chipbreaker for demanding applications

• Walter Tools Tiger‑tec Silver coating
• MW4 chipbreaker for stable chip control
• Rhombic 80° geometry with 0.8 mm radius
• Optimised for stainless steel and superalloys

Exceptional performance on tough alloys for higher productivity

The WSM20S grade, part of the Tiger‑tec Silver family, is a coated carbide solution developed for materials that generate heat and stick to the cutting edge. Its composition and coating increase tool life and support reliable cutting under elevated temperatures commonly encountered when machining stainless steels (ISO M) and heat‑resistant superalloys/titanium (ISO S). By selecting a grade that resists edge degradation, machining cycles become more predictable, which translates into fewer tool changes and reduced production interruptions. This rational focus on material compatibility and wear resistance improves process throughput and lowers overall machining cost per component.

Precise geometry and chip control for consistent surface quality

The insert’s MW4 chipbreaker and Rhombic 80° form are designed to deliver stable chip formation and a controlled cutting process. The 0.8 mm corner radius, paired with a 7° clearance angle, helps maintain a durable cutting edge while supporting good surface finish in interrupted or continuous cuts. These geometry choices reduce the risk of built‑up edge and vibration, which benefits repeatability and reduces rework. For machining operations that require reliable dimensional results and a consistent finish, the geometry and chip control work together to preserve component quality across batch runs.

Process security and economical machining for industrial use

Built for demanding environments, this turning insert supports higher cutting speeds and tough feeds without sacrificing stability, contributing to improved productivity. The grade’s emphasis on stable edge behaviour and the insert’s robust geometry help maintain a constant tool life across varied workpiece batches, enabling reliable scheduling and less downtime. Integration with standard toolholders and commonly used tool‑change systems means quick replacement and minimal set‑up time. For production facilities seeking dependable, repeatable performance, the insert delivers measurable operational benefits and supports a cost‑efficient machining strategy while maintaining component integrity.
