WCMT040204-FM4 WSM30S — Trigon 80° indexable insert for stainless steels and superalloys | Walter Tools

WCMT040204-FM4 WSM30S is an indexable turning/drilling insert engineered for demanding applications in stainless steels and heat-resistant superalloys, offering a balance of edge stability and chip control

• Tiger‑tec Silver coated grade WSM30S
• Trigon 80° insert for robust cutting
• FM4 chipbreaker for controlled chips
• Relief angle 7° and corner radius 0.4 mm

Robust grade for demanding materials

The WSM30S grade, part of the Tiger‑tec Silver series, is a coated carbide designed for severe machining conditions. Its coating system increases heat resistance and supports a stable cutting edge, which reduces edge wear when turning tough-to-machine alloys. This results in longer effective tool life and fewer interruptions for tool changes, supporting continuous production in industrial environments where material behaviour can lead to built-up edge and thermal loading.

Geometry that protects the cutting edge and improves accessibility

The Trigon 80° form combines strength with access to tight or interrupted cuts. A relief angle of 7° helps to lower radial cutting forces while the corner radius 0.4 mm gives a compromise between edge robustness and surface finish. The FM4 chipbreaker is tuned to produce short, manageable chips on stainless steels and similar materials, improving process security and reducing the risk of chip entanglement at higher feed rates.

Productivity through predictable performance

Designed for ISO material groups M (stainless steels) and S (superalloys/titanium), this insert promotes consistent results across a wide material spectrum. The combination of grade and geometry provides enhanced thermal stability and chip control, which can translate into reduced cycle times and lower tooling costs per component in serial production. The result is measurable process reliability and improved throughput for workshops that require repeatable quality.

Practical application notes and support

Suitable for both roughing and semi‑finishing passes depending on the chosen cutting parameters and holder, the insert performs best with coolant or high‑pressure flushing in difficult alloys to support chip evacuation. For help selecting compatible toolholders, feeds and speeds for specific grades of stainless steels or superalloys, Metav Werkzeuge can provide detailed guidance.

FAQ

What materials is this insert intended for?
The WCMT040204-FM4 WSM30S insert by Walter Tools is specified for ISO groups M and S, meaning it is intended for stainless steels and heat‑resistant superalloys/titanium, where thermal stability and chip control are critical.

Which cutter geometry improves edge life on interrupted cuts?
The Trigon 80° shape combined with a corner radius 0.4 mm on the WCMT040204-FM4 helps protect the cutting edge during interrupted and heavy cuts, providing a robust geometry for difficult turning operations.

How does the FM4 chipbreaker affect production?
The FM4 chipbreaker is engineered to produce short, controlled chips in tough materials, reducing the risk of chip build‑up around the tool and improving process security during longer production runs with the WCMT040204-FM4 WSM30S.

Is coolant recommended when machining with this grade?
For many stainless steels and superalloys, the Tiger‑tec Silver grade benefits from appropriate coolant or high‑pressure flushing to aid chip evacuation and heat management when using the WCMT040204-FM4 insert.

Where to get cutting data for this insert?
Cutting data sheets and application recommendations for the WCMT040204-FM4 WSM30S are available from Metav Werkzeuge; the supplier can provide suggested feeds, speeds and holder choices for specific materials.
