CNMG120408‑FW5 WSM10S indexable turning insert — Tiger‑tec Silver, negative 0° relief (Walter Tools)

A CNMG120408‑FW5 WSM10S indexable turning insert optimised for machining stainless steels and difficult‑to‑cut superalloys in demanding production environments

• Tiger‑tec Silver coating for edge stability
• WSM10S grade for stainless and superalloys
• Rhombic 80° insert with 0.8 mm corner radius
• Negative 0° relief with FW5 chipbreaker

High‑temperature performance and predictable edge life

The combination of the Tiger‑tec Silver series and the WSM10S coated‑carbide grade is specifically developed for machining stainless steels and heat‑resistant alloys. This engineered coating system supports stable chip formation and increases thermal resistance at the cutting edge, which reduces the risk of built‑up edge and unexpected tool failure. For production planning this translates into fewer insert changes and a more predictable tool‑life curve, supporting consistent cycle times and reduced machine downtime.

Geometry designed for secure cutting and superior surface quality

The rhombic 80° shape together with a 0.8 mm corner radius and the negative 0° relief deliver a secure cutting geometry that resists edge chipping under intermittent cuts or variable feed rates. The integrated FW5 chipbreaker promotes controlled chip evacuation, improving surface integrity and reducing secondary operations. These geometric choices are particularly advantageous when facing the toughness and heat‑sensitivity typical of superalloys and certain stainless grades, enabling dependable finishing and semi‑finishing results with predictable dimensional stability.

Process reliability and application guidance for production use

Adopting this insert supports a rational productivity strategy: improved edge stability lowers scrap risk, while consistent chip control simplifies coolant and chip‑conveyor management. The WSM10S grade and the insert’s design make it suitable for a range of turning operations on groups S and M according to ISO 513, meaning both superalloys and stainless steels can be processed with confidence. For specific cutting data, feeds and speeds, or to check compatibility with a particular toolholder series, consult the Metav Werkzeuge technical advisors to optimise cycle times and component quality.

FAQ

What materials is this insert suitable for?
The CNMG120408‑FW5 WSM10S indexable turning insert from Walter Tools is designed primarily for stainless steels (M) and heat‑resistant superalloys or titanium alloys (S), offering thermal stability and controlled chip formation.

What does the WSM10S grade indicate?
WSM10S denotes a Walter Tools coated‑carbide grade within the Tiger‑tec Silver family, optimised for tough, heat‑sensitive materials to balance edge stability and wear resistance during prolonged cutting.

How does the FW5 chipbreaker affect machining?
The FW5 chipbreaker on the CNMG120408‑FW5 WSM10S insert encourages short, controllable chips and better surface finish, which reduces interruptions and eases chip handling in continuous production.

Are the insert geometry and relief suitable for interrupted cuts?
Yes—the rhombic 80° form, 0.8 mm corner radius and negative 0° relief provide a robust edge geometry that resists chipping during interrupted cuts and variable feed conditions.

Can this insert be used for both finishing and roughing?
Depending on the chosen cutting parameters and toolholder setup, the CNMG120408‑FW5 WSM10S insert can be applied for both semi‑finishing and finishing operations on stainless steels and certain superalloys, with the coating and grade supporting stable performance.
