TNMG160412-NRS WSM20S indexable turning insert, Tiger‑tec Silver grade for rostfreier Stahl — Walter Tools

The TNMG160412-NRS WSM20S is a triangular 60° indexable turning insert engineered for heavy-duty and high-temperature machining of rostfreier Stahl and heat‑resistant superalloys.

• Tiger‑tec Silver coated carbide grade WSM20S
• Optimised for rostfreier Stahl and superalloys
• 0° negative rake with 1.2 mm corner radius
• Triangular 60° form for versatile insert positions

Stable performance when machining tough alloys

The Tiger‑tec Silver coating combined with the WSM20S grade provides a balanced mix of wear resistance and thermal stability, which results in stable chip formation when turning difficult-to-machine materials. For applications in rostfreier Stahl and nickel‑based alloys, the coated carbide substrate reduces the tendency for built-up edge and thermal softening, so the cutting edge remains effective for longer intervals. This means fewer interruptions for tool changes and predictable component quality in batch production.

Geometry that secures consistent surface quality

The triangular 60° insert form and the 0° negative rake give the cutting edge mechanical robustness and reduce edge chipping under interrupted cuts. The 1.2 mm corner radius smooths transfer of cutting forces, helping to maintain a uniform surface finish while protecting the cutting edge during heavy cuts. The NRS chipbreaker is optimised for controlled chip flow in demanding materials, improving tool life and process stability without sacrificing dimensional accuracy.

Practical benefits for workshop productivity

Designed as an indexable turning insert, this format enables rapid indexing and predictable repeatability in multi-shift operations. The combination of a coated hardmetal grade and a dedicated chip geometry lowers scrap risk and supports higher metal removal rates in suitable machines, thereby shortening cycle times. For production environments that require consistent outputs from rostfreiem components or high-temperature alloys, the tool contributes to reduced setup load and less frequent tooling interventions.
