SDMT120408-F57 WSM35G milling indexable insert – Tiger·tec Gold, Walter Tools

The SDMT120408-F57 WSM35G is a square 90° milling insert engineered for heavy‑duty machining of stainless steels and superalloys, offering stable edge life and reliable chip control.

• Tiger·tec Gold coated carbide grade WSM35G
• Designed for stainless steels and superalloys
• Square 90° insert with 0.8 mm corner radius
• 15° relief angle and F57 chipbreaker geometry

Increase uptime through thermal and edge stability

The combination of the Tiger·tec Gold coating and the WSM35G substrate delivers improved thermal resistance and a tougher cutting edge compared with standard grades. This results in more predictable wear behaviour when machining demanding materials classified as M (rostfreie Stähle) and S (heat‑resistant superalloys and titanium) under ISO 513. The specifically developed coating reduces adhesion and built‑up edge, which extends the usable life of the tool and reduces unplanned tool changes—direct benefits for cycle time and overall equipment effectiveness.

Reliable chip control for consistent surface quality

With its F57 chipbreaker geometry and a 0.8 mm corner radius, the insert produces controlled chip formation even under the adverse cutting conditions typical of stainless and high‑temperature alloys. The square 90° format provides a stable cutting shoulder and predictable engagement, supporting consistent surface finish and dimensional control across repetitive passes. In practical terms, this means fewer rejects and lower rework rates when tight tolerances and finish requirements are critical.

Stable cutting performance with clear process benefits

The 15° relief angle and the insert’s robust construction contribute to a stable cutting edge that resists chipping and thermal softening. This stability supports higher feed rates where the machine and fixture allow, translating into improved productivity without sacrificing component quality. The overall package emphasises process security and repeatability—key considerations for production environments where predictable tool life and part output are valued above short‑term cost savings.

Application guidance and machining recommendations

For roughing and medium finisher passes in stainless steels and superalloys, choose cutting parameters that balance tool life and material removal rate; the WSM35G grade is optimised for such situations. Use positive cutting depths and maintain coolant or suitable cutting fluid strategies to aid heat dissipation and chip evacuation. If further parameter optimisation is required for a specific alloy or geometry, Metav Werkzeuge can provide application support and test data to refine feeds and speeds.

FAQ

What materials is this insert best suited for?
The SDMT120408-F57 WSM35G insert is designed primarily for stainless steels (ISO group M) and for heat‑resistant superalloys and titanium (ISO group S), where thermal resistance and edge stability are required.

How does the F57 chipbreaker affect machining?
The F57 chipbreaker optimises chip formation for interrupted and continuous cuts in tough materials, improving evacuation and reducing the risk of built‑up edge when using the SDMT120408-F57 WSM35G insert.

What are the geometric specifics I should expect?
Expect a square 90° insert with a 0.8 mm corner radius and a 15° relief angle, providing a stable cutting shoulder and predictable dimensional results with the SDMT120408-F57 WSM35G.

Can this insert be used for finishing operations?
Yes; depending on the workpiece alloy and machine stability, the SDMT120408-F57 WSM35G can be used for medium finishing where its coating and geometry help maintain surface quality.

Is this a coated or uncoated grade?
This is a coated carbide grade utilising Tiger·tec Gold technology to enhance thermal resistance and reduce adhesion in demanding applications such as stainless steels and superalloys.
