CCMT09T308-FW4 WSM20S indexable turning insert — Tiger‑tec Silver, 0.8 mm corner radius (Walter Tools)

The CCMT09T308-FW4 WSM20S is an indexable turning insert designed for medium to heavy-duty machining of stainless steels and heat‑resistant alloys, offering a robust balance of edge stability and thermal resistance for demanding turning tasks

• Tiger‑tec Silver coated grade for heat resistance
• Suited to stainless steels and superalloys
• Rhombic 80° shape for versatile turning
• 0.8 mm corner radius for balanced strength

High productivity when machining stainless and heat‑resistant alloys

The combination of the WSM20S coated carbide grade and the Tiger‑tec Silver coating addresses common challenges in machining stainless steels and superalloys: poor thermal conductivity and a tendency to form built‑up edge. As a result, the insert promotes stable chip formation and reduces unexpected edge failure, allowing a higher and more consistent metal removal rate. The specific FW4 chipbreaker helps to break and evacuate chips reliably, which is particularly relevant when processing long or stringy chips common in these materials.

Predictable tool life and process security for production environments

Built with a tolerance class of M and a clearance angle of 7°, this indexable insert offers predictable cutting behaviour that supports reproducible cycle times. The moderate 0.8 mm corner radius provides a compromise between edge strength and surface finish, extending time between indexings while maintaining acceptable component quality. For workshops focused on throughput and repeatability, the grade’s thermal robustness translates into fewer tool changes and more consistent batch results, which contributes directly to cost efficiency and reduced downtime.

Geometry and handling tailored to versatile turning applications

The rhombic 80° geometry and insert size 09 deliver versatility across external and light profiling operations; the geometry enables stable positioning in common toolholders and good access to varied turning contours. The T3 plate thickness supports secure clamping and edge support during interrupted cuts. For teams evaluating tooling options, the insert’s combination of coated carbide, chipbreaker form and geometry simplifies tooling decisions and shortens setup time while preserving quality of finish.

FAQ

What materials is the CCMT09T308-FW4 WSM20S best suited for?
The CCMT09T308-FW4 WSM20S (Walter Tools) is optimised for stainless steels and heat‑resistant superalloys; the WSM20S grade and Tiger‑tec Silver coating focus on thermal stability and reliable chip control.

How does the FW4 chipbreaker affect performance?
The FW4 chipbreaker on this insert promotes controlled chip formation and evacuation, reducing the risk of entanglement and improving surface consistency during turning of long‑chip materials.

What does the 0.8 mm corner radius mean for productivity and finish?
A 0.8 mm radius balances edge strength and surface finish: it increases resistance to edge chipping for productivity while still enabling an acceptable surface quality without excessive cutting forces.

Is this insert suitable for interrupted cuts and roughing?
Yes; the rhombic 80° geometry combined with the T3 plate thickness offers good edge support and clamping stability, making the insert appropriate for many interrupted‑cut and roughing scenarios.

Can the insert be used in standard ISO toolholders?
The insert’s CCMT geometry and size 09 match common ISO turning holders designed for rhombic inserts; ensure holder compatibility with the CCMT seat and clamping method.
