WNMG080412-NRS WSM01 Trigon 80° turning insert — Walter Tools, Tiger‑tec Silver, 1.2 mm radius

The WNMG080412-NRS WSM01 is a coated cemented-carbide turning insert designed for face and profile turning of stainless steel and heat-resistant superalloys, offering a secure chip formation and durable cutting edge in demanding applications.

• Tiger‑tec Silver coating for wear resistance
• Trigon 80° geometry for high stability
• 0° negative rake for interrupted cuts
• Optimised for stainless steel and superalloys

Reliable material performance that reduces downtime

The combination of the Tiger‑tec Silver series and the WSM01 grade delivers a coated carbide solution that targets the typical problems encountered with stainless steel and high-temperature alloys: edge adhesion, poor heat dissipation and tool wear. The coating improves surface hardness and reduces chemical affinity between workpiece and insert, which in turn supports a stable chip formation and extends edge life. For operations where tool changes interrupt productive cycles, the result is fewer interventions and more consistent throughput — a direct contribution to process efficiency and predictable cycle times.

Geometry engineered for secure cutting and reproducible results

The Trigon 80° plate form with a 1.2 mm corner radius offers a robust edge for moderate to heavy cuts while maintaining dimensional control. The 0° negative rake angle increases edge strength and resists chipping during interrupted cuts or roughing passes, and the NRS chipbreaker geometry supports segmented chips suitable for tough-to-machine materials. These design choices translate into tangible process benefits: enhanced cutting stability, improved surface finish consistency and reduced risk of unexpected tool failure. Technical terms: a negative rake reduces cutting-edge vulnerability by orienting the cutting forces into the insert body rather than the cutting edge.

Practical application guidance and process confidence

Intended primarily for stainless steel and heat-resistant superalloys, this insert is a pragmatic choice where durability and edge integrity are priorities. The grade is particularly effective when machining materials that tend to work-harden or generate high temperatures at the cutting zone. While the insert is versatile across turning operations, matching feed, depth of cut and coolant strategy to material behaviour will maximise life and part quality. For tailored machining parameters and to verify suitability for a given workpiece, consulting Metav Werkzeuge’s technical advisers is recommended — they can suggest cutting data and holder compatibility to ensure repeatable outcomes.

FAQ

Is this insert suitable for high-temperature alloys such as Inconel?
The WSM01 grade with Tiger‑tec Silver coating is designed for heat‑resistant superalloys (ISO group S); it provides improved thermal resistance and edge stability for demanding materials.

What advantages does the Trigon 80° form offer in roughing operations?
The Trigon 80° geometry gives increased radial support and a stronger cutting edge, which enhances stability during roughing and interrupted cuts and helps maintain part accuracy.

How should the 0° negative rake be used in practice?
A 0° negative rake increases edge robustness; it is beneficial for interrupted cuts and heavier depths of cut, where edge strength outweighs the need for the lowest cutting forces.

Which materials are recommended for this insert?
Primary applications are stainless steel and heat‑resistant superalloys; the insert is configured to handle the poor heat conduction and high adhesive tendencies of these groups.
