DNMG150408-NRS WSM20S turning insert — Tiger·tec Silver, 0° negative rake (Walter Tools)

DNMG150408-NRS WSM20S is a rhombic 55° indexable turning insert engineered for controlled chip formation and reliable edge stability when machining stainless steel and high-temperature alloys.

• DNMG150408-NRS form, rhombic 55° geometry
• Tiger·tec Silver coated carbide grade WSM20S
• 0° negative rake for stable cutting
• 0.8 mm corner radius for robust edges

Secure chip control for demanding materials

The combination of the NRS chipbreaker and the Tiger·tec Silver coating delivers consistent chip breaking and reduced built-up edge in challenging cuts. Designed primarily for ISO groups M (stainless steel) and S (heat-resistant superalloys and titanium), this insert provides a reliable solution where temperature and adhesive wear are critical. The coated carbide structure of the grade WSM20S supports a secure cutting geometry, which reduces interruptions for tool changes and increases effective machining uptime while maintaining surface quality.

Geometry and edge strength that extend tool life

A rhombic 55° form with a 0° negative rake and 0.8 mm corner radius provides a compromise between edge strength and accessibility in a wide range of turning operations. These features result in improved corner stability and resistance to chipping during interrupted cuts. As a result, the indexable insert offers predictable wear progression and repeatable part tolerances, supporting efficient production runs and lower overall tooling cost per component through extended edge life.

Application guidance for optimal results

The insert is suited to workpieces that require secure heat handling and stable cutting edges, notably stainless steel and heat-resistant alloys. When selecting cutting parameters, consider the insert geometry and chipbreaker: moderate feeds combined with cutting speeds adapted for coated carbide grades typically yield the best balance of tool life and surface finish.

FAQ

What materials is this insert suitable for?
The DNMG150408-NRS WSM20S insert is suitable for stainless steel (ISO group M) and for heat-resistant superalloys and titanium (ISO group S), reflecting the design focus of the Tiger·tec Silver grade.

How does the NRS chipbreaker affect machining?
The NRS chipbreaker on this Walter Tools insert promotes controlled chip formation and reduces the risk of built-up edge, improving surface finish and process stability during continuous and interrupted turning.

Can this insert be used for interrupted cuts?
Yes, the combination of the 0.8 mm corner radius and the 0° negative rake provides enhanced edge strength, making the insert appropriate for many interrupted cutting scenarios when using the correct parameters.

Is the coating beneficial for high-temperature workpieces?
The Tiger·tec Silver coating applied to the WSM20S grade increases thermal resistance and wear protection, which is advantageous when machining materials that generate high cutting temperatures.
