WNMG080408-NMS WSM01 – Trigon 80° indexable turning insert, Tiger‑tec Silver (Walter Tools)

The WNMG080408-NMS WSM01 is a negative‑rake, trigon‑form indexable insert designed for demanding turning of rostfreier Stahl and heat‑resistant superalloys in heavy‑duty and finishing operations

• Tiger‑tec Silver coating for consistent edge life
• WSM01 grade for rostfreie Stähle and superalloys
• Trigon 80° form with negative 0° rake
• NMS chipbreaker for stable chip control

Enhanced process reliability for tough materials

The combination of the WSM01 coated carbide grade and the Tiger‑tec Silver series is engineered for stable cutting when machining rostfreier Stahl and heat‑resistant alloys. The coated microstructure reduces flank wear and supports reproducible edge retention, which translates into fewer insert changes and longer uninterrupted machining cycles. By choosing a grade optimised for high thermal loads and poor heat conduction materials, shops gain measurable improvements in process stability and less scrap from built‑up edge phenomena.

Geometry and chip control that improve surface quality

The Trigon 80° outline and negative 0° rake create a secure cutting edge that resists fracturing under interrupted cuts and heavy radial engagement. The NMS chipbreaker promotes predictable chip formation and evacuation even during high feed passes, reducing the risk of chip entanglement and improving finish consistency. The corner radius 0.8 mm offers a balance between edge strength and achievable surface finish, making the insert suitable for both robust roughing and controlled finishing operations.

Shop‑floor advantages and economical machining

As an indexable insert, the unit simplifies tooling logistics: fewer toolholders are needed across parts with similar geometries, and the coated grade supports extended tool life for lower unit costs over time. The insert’s specification eases process setup and repeatability, supporting shorter downtime for tool changes and increased machine utilisation. The brand pedigree of Walter Tools complements the technical attributes, providing familiar reference geometry and compatibility with standard toolholders across turning centres. The WNMG080408‑NMS WSM01 demonstrates a pragmatic mix of durability and predictable performance for demanding production environments.

FAQ

What materials is this insert designed to machine?
The WNMG080408‑NMS WSM01 is designed for machining rostfreier Stahl (ISO group M) and heat‑resistant superalloys (ISO group S) where thermal stability and controlled chip formation are required.

How does the NMS chipbreaker affect performance?
The NMS chipbreaker on the WNMG080408‑NMS WSM01 improves chip control and evacuation, supporting consistent surface finish and reduced risk of chip interference during medium to heavy cutting conditions.

What benefits does the Tiger‑tec Silver coating provide?
The Tiger‑tec Silver coating increases wear resistance and heat management on the cutting edge, which helps to extend tool life and maintain cutting performance when machining difficult alloys.

Is this insert compatible with common toolholders?
The trigon 80° form and standard WNMG designation ensure compatibility with standard toolholders designed for trigon inserts; holder selection should match the insert seat and clamping style for secure mounting.

What cutting strategy is recommended for the WSM01 grade?
Use the grade for operations with elevated temperatures and material stickiness where a coated carbide is preferable; moderate to lower cutting speeds with controlled feeds often yield the best balance between life and surface quality.
