WNMG080408-NRS WSM01 trigon 80° turning insert – coated carbide for rostfreier Stahl and superalloys by Walter Tools

The WNMG080408-NRS WSM01 is a negative-rake trigon insert engineered for high-demand turning of rostfreier Stahl and heat-resistant superalloys, offering stable cutting edges and reliable chip formation in interrupted or continuous cuts.

• Tiger-tec Silver coated carbide grade WSM01
• NRS chipbreaker for consistent chip control
• Trigon 80° geometry with 0.8 mm corner radius
• Negative 0° rake for heavy interrupted cuts

Reliable cutting performance for demanding materials

The combination of a Tiger-tec Silver coating with the WSM01 grade provides a balanced solution for machining tough-to-cut alloys. The coated carbide substrate increases resistance to thermal and mechanical wear, which helps to maintain a stable cutting edge under high temperatures. For applications involving rostfreier Stahl or nickel-based alloys, the coating supports secure chip formation and reduces the tendency for built-up edge, which in turn contributes to consistent surface quality and reduced tool exchanges.

Predictable chip control and surface finish

The integrated NRS chipbreaker is optimised to produce short, controlled chips in a wide range of cutting conditions, lowering the risk of chip entanglement and machine downtime. Controlled chip formation improves safety and facilitates continuous production runs, while the geometry of the insert promotes improved surface integrity. These factors help to increase process efficiency and can lead to a measurable improvement in overall machining throughput.

Geometry tailored for robustness and versatility

The Trigon 80° form combined with a 0.8 mm corner radius delivers a robust cutting edge suitable for moderate to heavy turning operations. The negative 0° rake angle enhances the insert’s resistance to shock and makes it well suited to interrupted cuts and hard inclusions commonly encountered in forgings or cast components. Together, these features enable the insert to offer both reliability and versatility across varied turning tasks.

Practical guidance for selection and use

Selecting the correct insert grade and geometry ensures consistent results and maximises tool life. Use the WSM01 grade where heat resistance and edge stability are priorities—particularly in the machining of rostfreier Stahl and superalloys. For best results, pair the insert with a rigid toolholder and appropriate cutting parameters for the workpiece material; this approach maintains edge condition and reduces unexpected downtime. When in doubt, seek application-specific recommendations to match feed, speed and depth of cut to the component requirements.
