SCMT09T308-FM4 WSM20S — indexable turning insert with FM4 chipbreaker for stainless steel and superalloys | Walter Tools

SCMT09T308-FM4 WSM20S is a coated carbide indexable insert engineered for demanding turning applications in stainless steel and high‑temperature alloys

• Tiger‑tec Silver coated grade WSM20S
• FM4 chipbreaker for secure chip control
• Square 90° geometry with 0.8 mm radius
• 7° clearance and T3 thickness for stability

Consistent chip control for uninterrupted production

The combination of the FM4 chipbreaker and the Tiger‑tec Silver coating prioritises reliable chip formation, which reduces the risk of built‑up edge and interruptions in the machining process. For components made from stainless steel and heat‑resistant alloys the chipformer promotes predictable swarf evacuation and lowers rework rates. Using a dedicated chip control geometry translates into fewer cycle stops and improved process throughput, making the operation more economical and easier to monitor.

Machining performance on challenging materials

The insert’s WSM20S grade is a coated carbide specifically balanced for the thermal and mechanical demands of superalloys and stainless‑type materials. The material grouping S / M indicates suitability for heat‑resistant superalloys and stainless steel, where heat resistance and edge stability are critical. The square 90° form and 0.8 mm corner radius support both robust roughing and controlled finishing cuts, delivering a consistent surface finish without compromising tool life.

Stable seating and repeatable results at the toolpost

A 7° clearance combined with T3 thickness enhances insert support and reduces vibration at the toolholder interface. This geometrical setup improves dimensional stability and repeatability across batches, which is particularly valuable in series production. The tolerance class M ensures consistent fitment in compatible toolholders, while the coated grade and optimised chipbreaker contribute to reliable edge life and fewer tool changes during a shift.

FAQ

What materials is this insert designed to machine?
The SCMT09T308-FM4 WSM20S insert is specified for stainless steel (group M) and for heat‑resistant superalloys and titanium (group S) according to the grade’s capabilities.

How does the FM4 chipbreaker improve machining of stainless materials?
The FM4 chipbreaker on this Walter Tools insert promotes stable chip formation and evacuation, helping to prevent built‑up edge when machining stainless steel and thereby improving surface integrity.

Is the insert suitable for both roughing and finishing operations?
Yes, the square 90° geometry with a 0.8 mm corner radius offers a compromise between strength for roughing and the ability to produce controlled finishes when cutting stainless steel and superalloys.

What does the Tiger‑tec Silver designation mean for tool life?
Tiger‑tec Silver is a coated carbide technology that enhances thermal resistance and edge stability; in the SCMT09T308-FM4 WSM20S it contributes to longer, more predictable tool life when machining demanding materials.

Does the insert require a special toolholder or clamping system?
The insert uses standard clamping for inserts of its ISO designation; the tolerance class M ensures repeatable seating in compatible toolholders for Walter Tools indexable turning systems.
