DCMT11T302-FM4 WSM20S Rhombic 55° turning insert, Tiger·tec Silver – Walter Tools

The DCMT11T302-FM4 WSM20S is a rhombic 55° turning insert engineered for secure, high‑productivity machining of rostfreier Stahl and difficult‑to‑cut superalloys.

• Tiger·tec Silver coating for edge stability
• Suitable for rostfreier Stahl and superalloys
• Rhombic 55° geometry with 7° relief
• FM4 chipbreaker for controlled chip formation

Improved process reliability through proven grade and geometry

The Tiger·tec Silver WSM20S grade provides a balanced combination of wear resistance and toughness, which supports stable chip formation and extends edge life during demanding operations. With the FM4 chipbreaker, chips are segmented and evacuated consistently, reducing the risk of built‑up edge and interruptions. The rhombic 55° form and 7° relief reduce radial cutting forces and help maintain dimensional stability, making this insert a dependable choice for production environments that require repeatable results.

Efficiency gains and easier process control on difficult materials

Thanks to its tailored grade and geometry, this turning insert reduces tool changes and improves cycle times when tackling materials that generate heat and adhesive wear. The modest corner radius of 0.2 promotes a reliable cutting edge for finishing and mixed‑turning tasks, offering a balance between edge strength and surface quality. For workshops seeking fewer reworks and consistent part tolerances, the combination of coating technology and chip control translates into measurable efficiency improvements and lower overall machining costs.

Durability and application scope for specialised machining

Designed for material groups M and S (rostfreier Stahl and heat‑resistant superalloys / titanium), the insert performs where conventional grades struggle, providing thermal stability and edge robustness. The insert’s construction and Walter Tools’ manufacturing standards contribute to predictable tool life and stable cutting performance, supporting elevated productivity and quality in serial production. Where process security and repeatable surface finish are priorities, this solution stands out as a technically sound investment.

FAQ

What materials are best machined with this insert?
The DCMT11T302-FM4 WSM20S insert is optimised for rostfreier Stahl and heat‑resistant superalloys (ISO groups M and S), offering thermal stability and secure chip control for these demanding materials.

How does the FM4 chipbreaker influence machining?
The FM4 chipbreaker on the WSM20S grade promotes segmented chips and reliable evacuation, which improves process stability and reduces the chance of built‑up edge during continuous turning.

What is the benefit of the rhombic 55° geometry with 7° relief?
The rhombic 55° shape combined with a 7° relief reduces radial cutting forces and enhances edge engagement, resulting in predictable tool behaviour and improved surface quality for turned parts.

Is the insert suitable for finishing operations?
Yes, the small corner radius of 0.2 and the balanced toughness of the Tiger·tec Silver grade support fine surface finishes while maintaining sufficient edge strength for typical finishing tasks.
