DNMG150404-FW5 WSM20S — Walter Tools turning insert, Tiger‑tec Silver, for stainless steels and superalloys

DNMG150404-FW5 WSM20S is a coated turning insert optimised for heavy‑duty turning of stainless steels and heat‑resistant superalloys, combining stable cutting edges with reliable chip control.

• Tiger‑tec Silver coating technology
• WSM20S grade for stainless steels and superalloys
• Rhombus 55° form with 0.4 mm corner radius
• 0° rake (negative) for cutting edge stability

Consistent cutting performance through a specialised grade

The WSM20S cutting grade with Tiger‑tec Silver coating is engineered for demanding turning tasks where heat and edge wear are critical factors. The coating reduces friction and improves thermal resistance, which in turn supports stable chip formation and prolongs tool life. This translates into fewer tool changes and a more predictable production rhythm, especially when machining materials that tend to work‑harden or build up on the edge. Such process reliability benefits throughput and reduces unplanned downtime.

Geometry that guarantees repeatable surface quality

The Rhombus 55° insert shape and the corner radius 0.4 mm deliver a balance between strength and finishing capability. A negative 0° rake promotes a robust cutting edge that resists chipping under interrupted cuts or heavy cross‑section removal. Together with the FW5 chipbreaker, these geometry features produce controlled chips and consistent surface finishes, meaning fewer secondary operations and improved part quality in serial production.

Designed for challenging materials: stainless steels and superalloys

This insert is specified for the ISO groups S and M — superalloys and stainless steels — which present high thermal loads and poor heat conduction. The WSM20S grade supports secure chip evacuation and minimises the risk of built‑up edge formation, which is essential when machining parts that require tight tolerances and consistent surface integrity. The combination of grade and chipbreaker is particularly suitable for applications where repeatable performance in demanding alloys is required.

Productivity and economical operation in everyday turning

By combining a wear‑resistant grade with a robust geometry, the insert contributes to longer tool life and steady process windows. The Tiger‑tec Silver technology helps maintain a stable cutting edge, reducing scrap rates and increasing usable tool life per insert. For production environments that prioritise uptime and reproducible part quality, this insert supports both efficiency and cost‑effectiveness through fewer interventions and consistent cycle times.

FAQ

Is this insert suitable for machining austenitic stainless steels?
Yes. The DNMG150404‑FW5 WSM20S insert is specified for ISO group M and is designed to handle the thermal and mechanical challenges of austenitic stainless steels.

Which materials in group S can be machined with this grade?
The WSM20S grade is suitable for many superalloys and heat‑resistant materials that require thermal stability and strong edge resistance during turning.

What advantage does the Tiger‑tec Silver coating bring?
Tiger‑tec Silver on the DNMG150404‑FW5 WSM20S insert reduces friction and improves heat resistance, supporting stable cutting edges and extended tool life under demanding conditions.

How does the FW5 chipbreaker affect chip control?
The FW5 chipbreaker combined with the insert geometry promotes controlled chip formation and evacuation, which helps maintain consistent surface finish and reduces secondary operations.

Can this insert be used for roughing and finishing operations?
Yes. The robust geometry and moderate corner radius allow for productive roughing while still delivering acceptable finishes, enabling flexible use across operation types with the same insert.
