CNMG120404-NMS WSM30S Rhombus 80° indexable insert – Walter Tools, Tiger·tec Silver, for stainless steel and superalloys

The CNMG120404-NMS WSM30S is an indexable turning insert designed for demanding applications in stainless steels and heat‑resistant superalloys; its Tiger·tec Silver coating and optimised chipformer ensure consistent machining performance.

• CNMG geometry Rhombus 80° insert
• Tiger·tec Silver coated carbide grade
• NMS chipformer for secure chip control
• 0° negative rake angle for stable cutting

Reliable machining of stainless steels and superalloys with fewer interruptions

The combination of the WSM30S coated carbide grade and the Tiger·tec Silver technology provides improved wear resistance and thermal stability when machining austenitic stainless steels and high‑temperature alloys. The insert’s specification targets materials classified under ISO group M (stainless steels) and S (superalloys and titanium), which are known for poor thermal conductivity and tendency to work‑harden; the coated substrate assists in maintaining a stable cutting edge and reduces the risk of built‑up edge formation. This results in more consistent cycle times and fewer tool changes, benefiting productivity in series production.

Process reliability and chip control that support higher productivity

Equipped with the NMS chipformer, the insert promotes predictable chip formation and evacuation even under the challenging cutting conditions typical of stainless steels and nickel‑base alloys. The 0° negative rake angle contributes to edge robustness and reduces the risk of chipping during interrupted cuts or tough feed conditions. Together, these features enable higher axial depths of cut and safer machining strategies, which in turn lower setup frequency and improve overall process stability on turning centres.

Geometry and tolerance that match precision requirements

The Rhombus 80° insert shape and a corner radius of 0.4 mm deliver a balance between edge strength and surface finish. The item is supplied in tolerance class M, and the geometry code CNMG120404‑NMS signals the insert dimensions and chipbreaker style at a glance for reliable tool selection. The plate thickness and form factor support secure clamping in standard tool holders designed for CNMG inserts, ensuring repeatable positioning and consistent part tolerances across tool changes.

Practical benefits for workshop planning and tool management

Selecting this insert family means addressing typical workshop challenges: wear‑resistant coating reduces frequency of regrinds or discards, the robust edge geometry supports demanding feeds, and the proven chipformer simplifies coolant and chip‑management decisions. For operations focused on stainless and heat‑resistant alloys, the WSM30S grade helps extend tool life and maintains surface integrity, reducing rework and enhancing first‑pass accuracy.
