SNMG120404-FM5 WSM10S — Square 90° indexable turning insert, Tiger‑tec Silver (Walter Tools)

A SNMG120404-FM5 WSM10S indexable turning insert engineered for heavy‑duty machining of stainless steel and high‑temperature superalloys, combining a robust geometry with a specialised chipbreaker.

• Tiger‑tec Silver coating technology
• Optimised FM5 chipbreaker for stable chips
• 0° negative rake for robust cutting

Engineered for demanding materials and longer tool life

The insert is built on a coated carbide substrate within the Tiger‑tec Silver series and the WSM10S grade, designed specifically for applications where heat and toughness challenge the cutting edge. Its formulation supports secure and repeatable chip formation when machining stainless steel and heat‑resistant alloys, reducing the risk of built‑up edge and improving component quality. The result is a combination of process reliability and predictable tool life that benefits repeat production runs and critical components.

Stable cutting performance and predictable process security

A designed FM5 chipbreaker and the 0° negative rake provide a stiff, damage‑resistant cutting edge for interrupted cuts and heavy feed conditions. The square 90° form together with a 0.4 mm corner radius offers strong edge support for grooving and profiling operations, while maintaining acceptable surface finishes. By improving edge stability and chip control, the geometry reduces downtime for insert changes and contributes to higher productivity in serial machining.

Easy integration, handling and application versatility

The SNMG geometry and standard 12 mm size with a 4 mm thickness allow simple mounting in common turning toolholders and quick replacement within established tool‑rooms. Tolerance class M ensures consistent fit and repeatability at the toolpost. The insert is suitable for both roughing and semi‑finishing operations in stainless steel and superalloys, offering a pragmatic solution when process engineers demand a balance of edge life and cutting performance.

FAQ

What materials is this insert best suited for?
The SNMG120404-FM5 WSM10S insert from Walter Tools is intended primarily for stainless steel and heat‑resistant superalloys (ISO groups M and S), where secure chip formation and edge stability are required.

How does the FM5 chipbreaker influence performance?
The FM5 chipbreaker promotes consistent chip control and stable evacuation under higher cutting forces, improving process security and surface finish when using the SNMG120404-FM5 WSM10S.

Can the insert withstand interrupted cuts?
Yes. The combination of a 0° negative rake and a 0.4 mm corner radius provides increased edge strength and resistance to chipping during interrupted or heavy engagement cuts.

Is the SNMG120404-FM5 WSM10S compatible with standard SNMG toolholders?
The insert conforms to the SNMG geometry and standard dimensions (12 mm, 4 mm thickness, tolerance class M), making it compatible with common SNMG toolholder systems.

What process benefits can be expected when switching to this grade?
Using the WSM10S grade and Tiger‑tec Silver technology typically yields more stable cutting edges, reduced downtime due to fewer edge failures, and improved repeatability across batch production.
