VCMT110304-FM4 WSM20S — Turning indexable insert with FM4 chipbreaker, Tiger‑tec Silver (Walter Tools)

VCMT110304-FM4 WSM20S is a rhombic 35° turning insert developed for stable machining of stainless steels and heat‑resistant superalloys in industrial production.

Tiger‑tec Silver coating for thermal stability
FM4 chipbreaker for predictable chip control
Rhombic 35° geometry for versatile turning

Reliable performance on stainless steels and superalloys

The insert is equipped with the WSM20S grade in the Tiger‑tec Silver family, optimised for materials classified as M and S under ISO 513. This combination improves thermal stability and supports secure cutting‑edge behaviour when machining tough, heat‑sensitive alloys. For production environments this means fewer interruptions from built‑up edge and a consistent surface finish across batches, contributing to predictable process outcomes and reduced scrap rates.

Controlled chips and consistent surface results

Thanks to the FM4 chipbreaker and the rhombic 35° layout, the geometry produces manageable chip formation even under challenging conditions. The insert’s 7° clearance and 0.4 mm corner radius are designed to balance edge strength and finishing capability, resulting in improved chip control and a steady contact zone at the tool tip. The outcome is smoother turning cycles, fewer manual interventions and a reliable part finish that supports downstream assembly processes.

Boosted productivity with process security

The design focuses on reproducibility and economy: robust flank support and the coated grade extend edge life and reduce insertion changes, which improves overall productivity. The insert suits serial and small‑batch production where process security is essential, enabling sustained cutting speeds and repeatable component quality. Using a dedicated Walter Tools grade helps maintain tool‑room standards and simplifies insert selection for engineers seeking dependable machining performance.

Application guidance and technical support

This turning insert is intended for conventional external and light finishing operations on stainless steel and heat‑resistant alloys; it performs best when paired with rigid tool holders and stable workholding. For specific cutting parameters, workpiece conditions or alternative materials, technical recommendations are available. If there is uncertainty whether this insert fits a particular application, Metav Werkzeuge provides tailored advice and cutting recommendations to ensure the best result for each machining task.
