CNMG120408-NRS WMP20S turning insert — Tiger·tec Silver, for stainless steel (Walter Tools)

The CNMG120408-NRS WMP20S is a rhombic 80° indexable turning insert designed for machining stainless steel under moderate to demanding conditions, offering stable chip formation and consistent edge life.

• Tiger·tec Silver coating for extended life
• Optimised for ISO M (stainless steel) applications
• Rhombic 80° geometry with 0° clearance
• NRS chipformer and 0.8 mm corner radius

Stable chip control for challenging stainless steels

The coated carbide grade and the NRS chipformer are engineered to secure reliable chip breakage when machining ductile and work-hardening materials. This combination reduces the risk of built-up edge and frequent interruptions, delivering a more predictable machining cycle. The Tiger·tec Silver coating improves heat resistance and reduces flank wear, meaning longer effective tool life and fewer insert changes during production runs.

Geometry that supports secure edge engagement and process reliability

The rhombic 80° geometry and negative 0° clearance provide a balance between cutting strength and accessibility in turning operations. The 0.8 mm corner radius gives a robust cutting edge that resists chipping under moderate interrupted cuts while still allowing acceptable surface finish. These geometric choices translate into steady metal removal rates and improved repeatability when producing serial parts or working on fixtures that demand consistent dimensions.

Material and coating synergy for longer service intervals

A coated cemented carbide grade, belonging to the Tiger·tec Silver family, is selected to cope with the thermal and adhesion challenges of stainless steels. The coating and substrate combination lowers chemical affinity between the chip and tool, promoting cleaner chip flow and less adhesion on the flank face. Consequently, maintenance intervals are extended, and parts throughput rises, which supports a more economical production rhythm.

Practical performance advantages on the shop floor

With its proven chip control and robust edge, this insert suits medium-to-heavy duty turning tasks in workshop and production environments. The insert’s designation and chipbreaker facilitate toolpath planning and process optimisation, enabling machinists and process engineers to maintain higher average cutting speeds and stable surface quality. The result is enhanced productivity and lower overall tooling consumption per finished component.

FAQ

What materials is this insert intended for?
The CNMG120408-NRS WMP20S insert is specifically designed for stainless steel (ISO M) machining and performs well under medium to robust cutting conditions.

How does the Tiger·tec Silver coating help in production?
The Tiger·tec Silver coating enhances heat resistance and wear behaviour, which supports longer tool life and improved process stability when machining stainless steels.

What does the NRS chipbreaker provide during turning?
The NRS chipformer promotes controlled chip fragmentation and safe evacuation, reducing built-up edge and interruptions in the machining cycle.

Is the geometry suitable for interrupted cuts?
The rhombic 80° geometry combined with a 0.8 mm corner radius offers a sturdy cutting edge that tolerates moderate interruptions while maintaining surface quality.

Can this insert be used for finishing operations?
Yes; with appropriate cutting data the insert provides acceptable surface finish, although the primary strength lies in stable general turning and medium-duty finishing.
