CNMG160612-NRS WSM20S indexable turning insert — Rhombic 80°, negative rake 0° (Walter Tools)

A CNMG160612-NRS WSM20S indexable turning insert engineered for heavy-duty machining of stainless steels and heat-resistant superalloys, offering the proven Tiger·tec Silver coating for enhanced edge stability and consistent chip formation

• Tiger·tec Silver coating technology
• Suitable for stainless steels and superalloys
• Rhombic 80° geometry, negative 0° rake
• NRS chipbreaker for stable chip control

Efficient cutting in demanding materials with proven coating benefits

The coated carbide grade WSM20S, part of the Tiger·tec Silver family, is designed to keep cutting edges stable when machining tough, heat-prone materials. As an indexable insert, the component prioritises repeatable performance and predictable wear behaviour, which reduces unexpected downtime. The combination of a specialised coating and a robust substrate results in improved resistance to built-up edge and thermal loading, yielding fewer tool changes and more consistent component tolerances.

Geometry that supports secure clamping and accurate facing

The rhombic 80° shape and negative rake 0° configuration provide a stable cutting interface for axial and radial forces common in heavy turning. This geometry enhances indexable insert rigidity, allowing machines to sustain higher feed and depth-of-cut settings where appropriate. The resulting benefit is a more economical cycle time with reliable dimensional control, particularly in repetitive production runs and batch machining of corrosion-resistant parts.

Controlled chip formation for safer, predictable machining

Integrated NRS chipbreaking ensures segmented chips and reduces the risk of long, entangling swarf when machining ductile or gummy alloys. Coupled with the corner radius 1.2 mm, the insert supports a balance between durable cutting edge strength and surface finish quality. Optimised chip control mitigates workpiece contamination and keeps toolholders and machine spindles operating within safe thermal and mechanical limits, contributing to stable process windows.

Application range and practical advantages at the workshop level

This insert is specified for material groups M and S according to ISO 513, namely stainless steel and heat-resistant superalloys/titanium. That targeted suitability makes the insert a sound choice for aerospace components, power-generation parts and medical device housings where material behaviour demands heat-resistant coatings and stable edge life. The insert format and standard clamping interfaces also support fast index changes, reducing non-productive time and simplifying inventory management across production lines.

FAQ

What materials is this insert suitable for?
The CNMG160612-NRS WSM20S insert from Walter Tools is specified for ISO groups M and S, making it suitable for stainless steel and heat-resistant superalloys or titanium alloys in demanding turning operations.

How does the Tiger·tec Silver coating benefit machining?
The Tiger·tec Silver coating on the WSM20S grade increases thermal resistance and edge stability, which helps to reduce built-up edge and prolong service life during the machining of heat-prone materials.

What advantages does the NRS chipbreaker provide?
The NRS chipbreaker offers reliable chip segmentation and evacuation, improving safety and productivity by preventing long swarf and maintaining a clean cutting zone when using the CNMG160612-NRS WSM20S insert.

Is the corner radius suitable for finishing operations?
With a corner radius of 1.2 mm, the insert provides a compromise between edge strength and surface finish; it is appropriate for many semi-finish and finish turning tasks where edge robustness is required.
