DNMG110404-FW5 WSM20S — Turning indexable insert, Tiger·tec Silver (Walter Tools)

DNMG110404-FW5 WSM20S is a high-performance turning insert designed for demanding machining of stainless steels and heat‑resistant superalloys.

• Tiger·tec Silver coating for wear resistance
• Grade WSM20S optimised for difficult alloys
• Rhombic 55° geometry with 0.4 mm radius
• Negative 0° relief and FW5 chipbreaker

Optimised grade and coating for challenging materials

The combination of the WSM20S grade with the Tiger·tec Silver coating delivers enhanced thermal stability and wear resistance when machining tough materials such as stainless steels and superalloys. This insert supports stable edge formation under elevated temperatures, which reduces the risk of built‑up edge and extends effective cutting life. The result is fewer tool changes, more predictable machining cycles and a measurable improvement in process efficiency for serial production.

Geometry designed for consistent chip control and surface quality

The Rhombus 55° form and the 0.4 mm corner radius produce a reliable cutting geometry that balances strength and finish capability. The FW5 chipbreaker is engineered to produce short, controllable chips under a wide range of depths of cut, improving swarf evacuation and reducing the likelihood of surface damage. A negative 0° relief increases insert robustness on interrupted cuts and hard workpieces, delivering stable results even in tougher turning applications.

Process reliability that supports productivity and reproducibility

By combining a modern coating system with a purpose‑built chipbreaker and a robust insert shape, this indexable solution promotes consistent part quality and predictable tool performance. The insert’s features are particularly suitable for sectors requiring repeatability — for example, aerospace and precision engineering where stable cutting edge behaviour and reliable chip control are essential. Application data and cutting parameters are available to adapt the insert to specific machine and material combinations, enabling an efficient, low‑risk integration into existing turning processes.

FAQ

Is this insert suitable for machining stainless steels?
Yes. The DNMG110404-FW5 WSM20S insert from Walter Tools is formulated for stainless steels (ISO group M), offering improved edge stability and reduced built‑up edge tendency.

What advantage does the FW5 chipbreaker provide?
The FW5 chipbreaker produces short, controllable chips and promotes consistent swarf evacuation; this improves surface finish and reduces the risk of chip entanglement during turning.

How does the negative 0° relief affect performance?
A negative 0° relief increases insert robustness on heavy or interrupted cuts, enhancing resistance to edge chipping and supporting secure machining of tougher materials.

What does the WSM20S grade mean?
WSM20S is a Walter Tools coated carbide grade within the Tiger·tec Silver family, optimised for heat and wear resistance when machining difficult‑to‑cut alloys such as stainless steels and superalloys.

Can this insert be used for finishing and roughing operations?
Yes. The Rhombus 55° geometry and 0.4 mm corner radius make the insert versatile; the cutting parameters and depth of cut determine whether the insert is used for finishing or more aggressive roughing tasks.
