VNMG160408-NMS WSM20S — Turning insert (Rhombus 35°, 0° relief) by Walter Tools

A VNMG160408-NMS WSM20S indexable insert designed for heavy-duty turning of stainless steels and heat-resistant superalloys, offering controlled chip formation and strong edge stability.

• Tiger·tec Silver coating for thermal resistance
• Robust WSM20S grade for difficult materials
• Rhombic 35° geometry with 0.8 mm radius
• Negative 0° relief for stable cutting

Optimised cutting performance for demanding alloys

The combination of the Tiger·tec Silver coating and the WSM20S grade targets the thermal and mechanical stresses of machining stainless steels and superalloys. The coated cemented carbide substrate improves heat resistance and reduces flank wear, which leads to longer in-process edge life and fewer interruptions for insert changes. With a rhombic 35° platform and specifically shaped chip control, this insert enables predictable chip evacuation in semi-finishing and finishing operations, reducing the risk of built-up edge and improving surface consistency. The result is improved productivity and more consistent component quality across batches.

Reliable edge stability and chip control for consistent results

Equipped with a dedicated NMS chipbreaker and a 0.8 mm corner radius, the insert delivers repeatable chip segmentation and a robust cutting edge that resists chipping under intermittent or heavy cuts. The 0° negative relief geometry enhances mechanical support of the cutting edge, allowing for stable engagement in deep cuts and interrupted machining. This stability translates into fewer tool interventions and reduced scrap rates, which is particularly valuable in series production and when machining difficult-to-cut alloys where process security is paramount.

Practical benefits for workshop and production planning

The insert’s form and grade selection simplify tooling decisions for mixed production runs that include both stainless steel and high-temperature alloys. Standardised designation and format make it straightforward to identify the correct insert for existing tool holders, while the combination of coating and substrate means longer service intervals and better cost-efficiency per component produced. For operations aiming to increase throughput without compromising surface finish, this insert offers a clear route to lower cycle times and improved consistency.

Application advice and material compatibility

The WSM20S grade is especially suited to materials classified under ISO group M (rostfreie Stähle) and S (heat-resistant superalloys and titanium). In practice, the insert performs well for roughing to finishing passes depending on the chosen cutting data and machine capabilities. When processing high-strength or heat-resistant materials, select conservative speeds and emphasise adequate coolant or cutting strategies to exploit the coating’s thermal advantages and to maintain a stable cutting edge over extended runs.

FAQ

What materials is this insert best suited for?
The VNMG160408-NMS WSM20S insert is designed primarily for stainless steels (ISO group M) and heat-resistant superalloys/titanium (ISO group S), exploiting the Tiger·tec Silver coating and the WSM20S grade for improved edge life.

How does the 0° relief affect machining performance?
A 0° negative relief provides superior mechanical support to the cutting edge, which helps the VNMG160408-NMS WSM20S withstand heavier cuts and interrupted machining while maintaining dimensional stability.

Which chipbreaker should be selected for mixed operations?
The integrated NMS chipbreaker is a balanced choice for controlled chip formation across finishing and semi-finishing passes when working with the WSM20S grade on stainless steels and superalloys.

Can the insert be used for finishing passes to achieve a good surface?
Yes, when paired with appropriate cutting data and machine rigidity, the combination of 0.8 mm corner radius, robust grade and coating enables fine surface results during finishing operations.

What are the main advantages of the Tiger·tec Silver coating on this insert?
The Tiger·tec Silver coating improves thermal resistance and wear behaviour, which extends edge life and supports process reliability during continuous production with demanding materials.
