VCMT160408-FM4 WSM30S – Turning insert for stainless steels and superalloys (Tiger·tec Silver, Rhombic 35°, Walter Tools)

The VCMT160408-FM4 WSM30S is a coated carbide indexable turning insert optimised for machining stainless steels and heat‑resistant superalloys, offering robust edge stability and secure chip control in demanding turning operations.

• Tiger·tec Silver coated carbide for hard materials
• FM4 chipbreaker for secure chip control
• Rhombic 35° form with 0.8 mm corner radius
• 7° clearance angle for reliable cutting edge

Reliable performance on stainless steels and superalloys

The Tiger·tec Silver WSM30S grade is a coated carbide designed specifically for materials that are difficult to machine, such as stainless steels and superalloys. The coating improves heat resistance and reduces adhesion at the cutting edge, which supports a stable cutting process and reduces the tendency for built‑up edge. For operations where material stickiness and high thermal loads are common, this insert maintains dimensional consistency and prolongs tool life, translating into fewer interruptions in production and better repeatability across batches.

Geometry that secures chip flow and surface quality

The insert’s FM4 chipbreaker is engineered to manage chip formation under interrupted or continuous turning conditions, promoting controlled chip curls and safe evacuation. Combined with the Rhombic 35° form and a 0.8 mm corner radius, the geometry balances edge strength with accessibility for profiling and external turning. The 7° clearance reduces rubbing and lowers cutting forces, helping to maintain surface finish while protecting the cutting edge against premature wear. These design choices result in consistent component quality and reduced secondary finishing.

Productivity advantages and process security

By pairing a high‑performance grade with optimised geometry, the insert supports higher machining security and predictable tool life, which is critical in series production and short‑cycle manufacturing. Stable edge behaviour under thermal stress reduces scrap rates and rework, improving overall tool cost per component. Where machining stainless or high‑temp alloys leads to rapid edge degradation with standard grades, the WSM30S demonstrates extended service life and reliable performance, making process planning more economical and less sensitive to operator variation.

Application guidance and recommended use

This insert is suitable for a variety of turning tasks on tough materials according to ISO group designations S and M. Use the FM4 chipbreaker and recommended cutting parameters for medium to heavy cuts where chip control is vital. For fine finishing passes, the combination of the coated grade and the moderate corner radius provides a balance between surface integrity and edge robustness.
