CPMT09T304-FM4 WSM20S — Rhombic 80° indexable insert for stainless steel (Walter Tools)

The CPMT09T304-FM4 WSM20S is a rhombic 80° indexable turning and boring insert engineered for demanding machining of stainless steels and heat‑resistant alloys, combining a robust corner profile with a specialised chipbreaker for reliable chip control.

• Tiger·tec Silver coating technology
• Optimised FM4 chipbreaker geometry
• 11° relief for secure cutting edge
• 0.4 mm corner radius for versatile machining

High-performance coating and grade for demanding materials

The combination of the Tiger·tec Silver coating and the WSM20S grade provides enhanced thermal stability and improved wear resistance in challenging conditions. This coating system reduces adhesion and helps maintain a stable edge when machining stainless steel and Ni‑base superalloys, which are prone to built-up edge and high cutting temperatures. The result is greater process reliability and longer tool life, translating into fewer interruptions and more consistent production outputs.

Precision geometry for stable cutting and chip control

Equipped with an FM4 chipbreaker and an 11° relief, the insert promotes controlled chip formation and a secure cutting action. The 0.4 mm corner radius balances edge strength with profile accuracy, making the insert suitable for general turning and finishing passes where a combination of robustness and surface quality is required. The rhombic 80° shape enables a wide range of approach angles, increasing flexibility in toolholder selection and setup.

Economic benefits through predictable performance

The coated cemented carbide composition and the proven grade concept support durable cutting edges under thermal and mechanical load, reducing the frequency of index changes. For production environments working with stainless or heat‑resistant alloys, this means lower tool consumption and improved uptime. The design is aimed at users seeking stable chip control and reproducible results across batches, delivering tangible efficiency gains in everyday machining tasks.

FAQ

What materials is this insert designed for?
The CPMT09T304-FM4 WSM20S insert is designed primarily for stainless steel and heat‑resistant superalloys, utilising the WSM20S grade to support secure chip formation and edge stability.

How does the Tiger·tec Silver coating improve performance?
The Tiger·tec Silver coating enhances thermal resistance and reduces adhesion on the cutting edge, which helps to maintain stable performance when machining tough, heat‑generating materials.

Which chipbreaker is fitted and what is its benefit?
The insert features an FM4 chipbreaker developed for reliable chip control, enabling consistent chips and reduced risk of tangling in turning and boring operations.

Can this insert be used for finishing passes?
Yes — the 0.4 mm corner radius and rhombic 80° geometry make the insert suitable for a range of finishing and semi‑finishing operations while maintaining edge strength.

Is the insert compatible with standard indexable holders?
The rhombic 80° form is compatible with common indexable turning and boring holders designed for CPMT‑style inserts; selection of the correct seat and clamp is recommended for optimal performance.
