CCMT09T304-FM4 WSM20S turning indexable insert — Tiger‑tec Silver for stainless steels and superalloys | Walter Tools

A CCMT09T304-FM4 WSM20S rhombic 80° turning insert designed for reliable performance in stainless steels and heat‑resistant superalloys

• Tiger‑tec Silver coating for heat resistance
• Designed for stainless steels and superalloys
• 7° clearance angle for secure chip control
• 0.4 mm corner radius for precise finishing
• Rhombic 80° form with FM4 chipbreaker

High‑temperature coating that stabilises the cutting edge

The combination of the Tiger‑tec Silver coating and the WSM20S carbide grade provides a measured increase in thermal resistance and edge stability when machining tough materials. Coatings in the Tiger‑tec Silver family are engineered to reduce built‑up edge and abrasion under higher cutting temperatures; this means fewer unplanned tool changes and more predictable component quality. In practical terms, the coated substrate supports consistent performance in applications where heat generation is significant, such as interrupted cuts or long turning passes in stainless steels and superalloys.

Geometry engineered for consistent surface quality and chip control

The rhombic 80° shape combined with a 7° clearance produces a cutting geometry that balances strength and accessibility for a wide range of turning tasks. The FM4 chipbreaker is tuned to promote controlled chip formation in ductile and work‑hardening materials, reducing the risk of long, stringy chips that can damage the part or tool. The 0.4 mm corner radius offers a compromise between edge strength and the ability to achieve fine surface finishes, making this insert suitable for finishing and light to medium turning operations where repeatable surface integrity is required.

Design features that support steady productivity and tool life

Built as a turning indexable insert with tolerance class M and thickness T3, this component is intended for series production environments where repeatability is essential. The grade and coating combination encourages stable wear patterns and predictable reconditioning intervals, which improves process planning and reduces downtime. Because the insert is indexed rather than resharpened, replacement is rapid and machining parameters remain consistent across insert changes, supporting leaner workflows on CNC lathes and turning centres.

Practical application guidance for reliable setup

This insert is recommended where machining of stainless steels or heat‑resistant alloys is the priority and where a balance between edge life and surface quality is required. For finishing passes choose moderate feeds with the 0.4 mm corner radius to preserve surface integrity; for more aggressive material removal, consider inserts with a larger radius or different grade. The rhombic angle permits access to shoulder and contour features while maintaining cutting stability. For specific holder choices or parameter windows tailored to a particular workpiece and machine, technical advice from Metav Werkzeuge can help fine‑tune the set‑up and cutting strategy.

FAQ

Which materials is this insert best suited for?
The CCMT09T304-FM4 WSM20S insert from Walter Tools is designed primarily for stainless steels and for heat‑resistant superalloys (and titanium depending on application geometry), offering stable chip formation and edge integrity.

What advantages does the Tiger‑tec Silver coating provide?
The Tiger‑tec Silver coating increases thermal resistance and reduces adhesive wear, which helps the insert maintain a sharp, stable cutting edge under elevated temperatures common when machining stainless steels and superalloys.

How does the FM4 chipbreaker influence machining results?
The FM4 chipbreaker promotes short, manageable chips in ductile materials, improving surface finish consistency and reducing the risk of chip entanglement during continuous turning operations.

When is the 0.4 mm corner radius recommended?
A 0.4 mm corner radius is suitable for finishing and light to medium turning where surface quality is important while still providing sufficient edge strength for stable tool life.

Is this insert suitable for series production?
Yes; the insert’s coated grade, defined geometry and tolerance class M make it a reliable choice for series production, where repeatability and predictable tool life are required.
