WNMG080404-NMS WSM01 — Trigon 80° indexable turning insert with Tiger‑tec Silver coating (Walter Tools)

WNMG080404-NMS WSM01 is an indexable turning insert designed for heavy-duty machining of stainless steels and heat-resistant superalloys

• Tiger‑tec Silver coating for thermal stability
• Optimised NMS chipbreaker for secure chips
• Trigon 80° form for enhanced cutting strength
• 0.4 mm corner radius for fine surface finish

Stable machining for stainless steels and superalloys

The combination of a coated carbide grade and the Tiger‑tec Silver series provides thermal resistance and improved wear behaviour when machining difficult-to-cut materials. The inserted grade WSM01 is optimised for rostfreie Stähle (ISO group M) and heat-resistant alloys (ISO group S), which typically cause high temperatures and built-up edge formation; the coating delays wear and supports a stable cutting edge, resulting in longer tool life and fewer insert changes. This stability translates directly into predictable cycle times and reduced downtime in serial production.

Reliable chip control that maintains process security

Built with the NMS chipbreaker, the insert ensures consistent chip formation under interrupted and continuous cuts alike. Controlled chips lower the risk of workpiece damage and tool collisions, while secure chip evacuation helps maintain coolant flow and tool visibility. In practice, this reduces scrap rates and supports a more consistent surface finish, which is particularly relevant for components where rework would be costly. The insert’s negative 0° rake contributes to robustness in heavy cuts and hard-facing operations.

Geometry and edge design that protect component quality

The Trigon 80° shape and a 0.4 mm corner radius combine to provide a strong cutting geometry that resists breakage and distributes cutting forces over a larger area. The compact plate format with thickness designation 04 is engineered to withstand the mechanical stresses of turning operations in tougher materials. As a result, operators benefit from reduced vibration and improved dimensional consistency, which supports tighter tolerances and better repeatability on finished parts.

Practical compatibility and selection guidance

This insert is supplied in the WNMG080404-NMS form with the WSM01 grade and is intended for use where rostfreie Stähle and superalloys are predominant. The designation signals suitability for medium to heavy cutting conditions; matching the insert to the correct holder geometry and cutting parameters is essential. When cutting speeds are reduced and feed rates adjusted to material demands, the coated carbide and chipbreaker combination will deliver the expected balance of tool life and surface quality.

FAQ

What materials is this insert suitable for?
The WNMG080404-NMS WSM01 insert is optimised for stainless steels (ISO group M) and heat‑resistant superalloys (ISO group S), offering thermal stability and controlled chip formation.

Which chipbreaker does the insert use and why does that matter?
This insert features the NMS chipbreaker, which promotes secure chip control and consistent surface finishes, especially under varying cutting conditions.

How does the Tiger‑tec Silver coating benefit machining?
The Tiger‑tec Silver coating increases thermal resistance and reduces flank and crater wear, which extends tool life during demanding turning operations.

Is the negative 0° rake suitable for heavy cuts?
Yes, the 0° negative rake supports mechanical robustness and is well suited to heavier cuts and interrupted machining where edge strength is required.

Can this insert be used for finishing to high surface quality?
With the 0.4 mm corner radius and appropriate cutting parameters, the insert can achieve fine surface finishes while maintaining stability in the cut.
