CNMG120408-NMS WSM10S Drehwendeschneidplatte — Tiger‑tec Silver, for rostfreier Stahl and superalloys (Walter Tools)

The CNMG120408-NMS WSM10S is a rhombic 80° indexable turning insert designed for heavy-duty turning tasks in rostfreier Stahl and heat‑resistant superalloys, offering a balance of edge stability and controlled chip formation.

• Tiger‑tec Silver coated carbide for durability
• Optimised NMS chipbreaker for secure chip control
• Rhombic 80° shape with 0.8 mm corner radius
• 0° negative rake for robust cutting geometry

Increased productivity thanks to coating and grade

The combination of the Tiger‑tec Silver coating and the WSM10S grade delivers measurable gains in process reliability and tool life. The coated carbide structure resists thermal wear and maintains a stable cutting edge under elevated temperatures, which reduces indexing frequency and downtime. For production environments processing rostfreier Stahl or heat‑resistant alloys, this results in fewer tool changes and more consistent cycle times, supporting leaner workflows and predictable output.

Stable chip control and reliable cutting in difficult materials

The dedicated NMS chipbreaker geometry promotes consistent chip formation when machining tough materials that tend to produce stringy or built‑up edges. For rostfreier Stahl and nickel‑based superalloys, chip control is critical to avoid surface damage and tool overload; the insert’s design helps evacuate chips reliably and reduces secondary operations. This behaviour contributes directly to improved surface finish and a reduction in rework, making the insert suitable for demanding part families and repeatable production runs.

Robust geometry that simplifies setup and improves safety margins

With a rhombic 80° form, 0° negative rake and a 0.8 mm corner radius, the insert offers a stable cutting geometry for interrupted cuts and varying engagement angles. The negative rake enhances edge strength and provides a safety margin in roughing operations, while the modest corner radius balances edge robustness with finish capability. These geometric choices simplify process planning: fewer trials are needed to find a reliable starting point, and clamping and toolholding risks are reduced during heavy cuts.

Practical selection advice for workshop and production planning

The insert’s specification and chipbreaker suit medium to heavy turning in rostfreier Stahl and alloys classified under ISO groups M and S; it is therefore a practical choice where material toughness and thermal load are significant concerns. When replacing conventional grades that suffer rapid edge breakdown in such materials, consider this insert to improve tool life and maintain dimensional stability across batches. For tailored recommendations on grades, geometries or compatible toolholders, Metav Werkzeuge offers consultation to align the insert selection with the intended machining strategy.

FAQ

What materials is this insert suitable for?
The CNMG120408-NMS WSM10S insert is designed for machining rostfreier Stahl and heat‑resistant superalloys (ISO groups M and S), where the grade’s thermal resistance and edge stability are required.

How does the NMS chipbreaker benefit production?
The NMS chipbreaker on the WSM10S grade promotes controlled chip formation and evacuation, reducing the risk of built‑up edge and improving surface quality during continuous and intermittent turning operations.

Is the 0° negative rake suitable for roughing?
Yes, the 0° negative rake increases edge strength and is well suited to roughing and interrupted cuts, providing a robust geometry that tolerates higher mechanical loads.

Which toolholders are compatible with this insert shape?
Rhombic 80° indexable insert holders that accept CNMG‑style inserts and the CNMG120408‑NMS geometry are compatible; ensure correct clamping and seating to maintain edge stability.

What are the main benefits of the Tiger‑tec Silver series on this insert?
The Tiger‑tec Silver coating enhances thermal resistance and reduces wear, delivering improved process security and longer tool life when machining demanding alloys.
