CNMG120408-NMS WSM30S indexable turning insert – Tiger·tec Silver for stainless steels and superalloys (Walter Tools)

the CNMG120408-NMS WSM30S insert is a coated carbide indexable turning insert designed for demanding turning of stainless steels and heat‑resistant alloys

• Tiger·tec Silver coated carbide grade WSM30S
• Optimised chip control with NMS chipbreaker
• Robust 0° negative rake for interrupted cuts
• Rhombic 80° form with 0.8 mm corner radius

High performance on tough materials for consistent productivity

The combination of the Tiger·tec Silver coating and the WSM30S grade provides a reliable basis for machining stainless steels and high‑temperature alloys. The coating technology increases wear resistance and supports stable chip formation, reducing the risk of built‑up edge and prolonging tool life. The rhombic 80° geometry and compact form factor deliver a stable cutting edge that resists thermal and mechanical loading, which translates into fewer tool changes and steadier cycle times. These technical properties are particularly valuable in production environments where consistent output and minimal downtime are required.

Improved process security and measurable economy

Equipped with the NMS chipbreaker and a 0° negative relief, this insert is built for process reliability under challenging conditions such as interrupted cuts and hardening layers. The 0.8 mm corner radius balances edge strength and surface finish, making it possible to achieve acceptable roughness while maintaining long edge life. The result is tangible: reduced rework, predictable tool‑change intervals and improved machining consistency. Walter Tools’ material and geometry pairing supports high process security, which helps to lower overall machining costs through higher productivity and longer tool life.

Clear application guidance for set‑up and material selection

According to the supplied specification, the insert is targeted at the ISO material groups M and S, meaning rostfreie Stähle (stainless steels) and heat‑resistant superalloys/titanium. For these workpiece families, the coated carbide and chipbreaker combination promotes controlled chips and less thermal load at the cutting edge. When integrating the insert into a toolholder system, select a stable clamping solution and set feeds and speeds appropriate for the chosen alloy and workpiece condition; the robust geometry tolerates conservative increases in cutting parameters to boost productivity. The CNMG120408‑NMS WSM30S is therefore suitable for series production where repeatability and predictable tool performance are priorities.

FAQ

What materials is this insert intended for?
The CNMG120408-NMS WSM30S insert is specified for ISO groups M and S, making it suitable for stainless steels and heat‑resistant superalloys or titanium depending on the toolset and cutting parameters.

How does the Tiger·tec Silver coating benefit machining?
The Tiger·tec Silver coating on the WSM30S grade enhances wear resistance and thermal stability, improving chip control and extending edge life during machining of demanding materials.

What advantage does the 0° negative relief offer?
A 0° negative relief provides a strong cutting edge that withstands mechanical shocks and interrupted cuts, offering higher process security in heavy or interrupted turning operations.

Can the NMS chipbreaker be used for finishing passes?
The NMS chipbreaker is optimised for controlled chip formation; finish quality will depend on cutting parameters and machine rigidity, but the 0.8 mm corner radius supports a balance between edge strength and surface finish.

Is this insert compatible with standard CNMG toolholders?
The insert follows the CNMG form and is intended for compatible clamping systems; correct seating and secure clamping in a CNMG toolholder are essential for achieving the described performance.
