VBMT160404-FM6 WSM20S turning insert — Rhombic 35°, Tiger‑tec Silver (Walter Tools)

VBMT160404-FM6 WSM20S is a single‑sided indexable turning insert engineered for demanding finishing and semi‑finishing operations on stainless steel and superalloys, combining a compact Rhombic 35° profile with a low 5° clearance angle for stable cutting performance

• Tiger‑tec Silver for enhanced edge stability
• FM6 chipbreaker for controlled chip formation
• Rhombic 35° geometry for versatile turning
• 0.4 mm corner radius for fine surface finishes

High‑performance machining of stainless steel and superalloys

The insert delivers predictable metal removal in difficult‑to‑cut materials thanks to the WSM20S grade and the Tiger‑tec Silver coating, which together enhance thermal resistance and wear behaviour. The carbide substrate and PVD/CVD‑type coating strategy (as applied in the Tiger‑tec Silver series) support continuous cutting at elevated temperatures, reducing edge build‑up and extending tool life. For manufacturers requiring consistent tolerances in serial production, the FM6 chipbreaker ensures a controllable chip form, cutting down interruptions and improving process reliability.

Geometry and edge design that improve surface quality and tool life

With a Rhombic 35° shape and a low 5° relief angle, this indexable insert combines accessibility to varied component profiles with a secure cutting edge. The 0.4 mm corner radius is suited to finishing passes where surface integrity matters, while the insert thickness and seat form contribute to rigidity in the toolholder. These design choices reduce vibration and distribute cutting forces evenly, which helps to maintain dimensional stability and achieve better surface finishes with fewer rework cycles. The combination of form and grade makes the component effective for both interrupted and continuous turning operations.

Productivity and process security for modern turning shops

Adopting this insert can raise throughput by maintaining a sharp cutting edge over longer tool life, lowering tool change frequency and supporting predictable cycle times. The FM6 chipbreaker, developed for stable chip control, minimises recutting and tool‑holder contamination, promoting safer, uninterrupted production. Suppliers and production managers benefit from the repeatable performance of the grade: consistent wear patterns simplify tool management and reduce downtime. For workshops transitioning to tougher alloys, the insert offers a balance of productivity and ease of use, helping to safeguard component quality and overall process efficiency.
