DCMT11T304-FM6 WSM20S — Turning insert, Tiger·tec Silver, FM6 chipbreaker (Walter Tools)

DCMT11T304-FM6 WSM20S is an indexable turning insert engineered for reliable chip formation when machining stainless steel and heat‑resistant superalloys.

• Tiger·tec Silver coating for thermal stability
• FM6 chipbreaker for secure chip control
• Rhombic 55° geometry with 7° clearance
• 0.4 mm nose radius for fine surface finish

Maximise process stability with a purpose‑built grade

The WSM20S grade, manufactured within the Tiger·tec Silver family, is a coated cemented‑carbide solution designed specifically for demanding materials such as stainless steel and heat‑resistant superalloys. The chemical and mechanical properties of these workpieces tend to generate high temperatures and tend to work‑harden; the coating and substrate combination therefore prioritises thermal resistance and edge stability. This results in a reduction of flank wear and more predictable tool life, which supports consistent cycle times and fewer interruptions in production. The combination of grade and coating enables users to increase cutting parameters within safe limits and improve overall throughput.

Precision geometry and chip control for improved surface quality

The insert’s Rhombic 55° form and 7° clearance angle are selected to balance cutting forces and access in turning operations, while the FM6 chipformer actively shapes short, controlled chips in interrupted and continuous cuts. A 0.4 mm nose radius supports improved surface finish without excessive cutting loads and is particularly useful for finishing passes where dimensional tolerance and quality are decisive. Because the chip control is handled at the insert geometry level, machining stability is improved and secondary operations for chip management are reduced — a rational improvement that lowers cycle time and enhances operator safety.

Practical integration and reliable performance in series production

As an indexable insert, the part is suitable for serial production environments where quick indexation and reproducible results matter. The insert thickness T3 and nominal size 11 provide mechanical robustness for moderate to heavy cutting engagements while keeping toolholder compatibility straightforward. The tolerance class M ensures standard interchangeability and predictable seating in commonly used toolholders. Walter Tools’ manufacturing standards support repeatable performance, making these inserts a pragmatic choice for workshops seeking a balance of productivity and economical tool use. For specialised applications, the insert’s behaviour in high‑temperature cutting can be matched with appropriate feeds and speeds determined in trial cuts.
