SCMT09T308-FM6 WSM20S — Indexable turning insert with Tiger·tec Silver and FM6 chipbreaker (Walter Tools)

SCMT09T308-FM6 WSM20S is a precision turning insert engineered for long tool life and secure chip control in stainless steels and heat‑resistant superalloys

• Tiger·tec Silver coating for durable edges
• WSM20S grade for stainless and superalloys
• FM6 chipbreaker for consistent chip control
• 7° clearance with 0.8 mm corner radius

Proven cutting performance for difficult materials

The SCMT09T308-FM6 WSM20S insert combines a Tiger·tec Silver surface treatment with a WSM20S coated carbide body to address the thermal and mechanical demands of tough materials. The grade has been developed for machining stainless steel and superalloys, where heat resistance and edge stability are critical. Through improved adhesion and a hard, wear‑resistant coating, the insert extends service intervals and preserves a predictable cutting edge, supporting higher productive running times and fewer unexpected tool changes.

Consistent chip control and improved surface quality

A dedicated FM6 chipbreaker geometry ensures controlled chip formation and evacuation even at elevated cutting temperatures. The combination of the chipbreaker with a 7° clearance and a 0.8 mm corner radius helps to reduce built‑up edge and stabilise cutting forces, which directly benefits the surface finish of the workpiece. Stable chips and lower vibration lead to repeatable part quality and reduce the need for downstream finishing, making the insert a reliable choice for serial production and demanding one‑off work.

Geometry and tolerance for repeatable accuracy

The square configuration (square 90°) and the compact size lend themselves to robust seat contact and low radial deflection during turning. Manufactured to tolerance class M with a plate T3 thickness, the component offers consistent positional accuracy in pocketed toolholders and turret systems. As an indexable turning insert, it combines convenient indexing with dimensional stability, enabling straightforward re‑use of remaining edges and predictable tool life across multiple machining cycles.

Production advantages and application guidance

Designed by Walter Tools, this insert supports higher productivity through prolonged edge life and fewer interruptions for insert changes. The grade’s compatibility with stainless steel and heat‑resistant alloys reduces the need for multiple specialised grades in mixed‑material production. For best results, pair the insert with suitable carbide toolholders and adapt feeds and speeds to the workpiece alloy; this approach maximises tool life and process reliability while maintaining consistent dimensional accuracy.
