DCMT11T302-FM4 WSM30S indexable turning insert, Tiger‑tec Silver, for stainless steel and superalloys — Walter Tools

A DCMT11T302-FM4 WSM30S indexable turning insert engineered for secure chip control and extended tool life in stainless steel and high‑temperature alloys.

• Tiger‑tec Silver coating for high process reliability
• WSM30S grade optimised for stainless steel
• Rhombus 55° insert form for versatile turning
• FM4 chipbreaker for controlled chip formation
• 0.2 mm corner radius with 7° clearance

Longer, more consistent edge life for difficult materials

The combination of the Tiger‑tec Silver coating and the WSM30S grade provides enhanced thermal resistance and improved wear characteristics when machining stainless steel and superalloys. These materials tend to generate heat and sticky chips; the coated carbide substrate reduces chemical affinity and supports a stable cutting edge, which in turn lowers the frequency of insert changes. The result is a measurable increase in process reliability and fewer interruptions during component production.

Geometry that improves chip control and surface quality

The Rhombus 55° form together with the FM4 chipbreaker and 0.2 mm corner radius is designed to balance accessibility and robustness. The 55° shape gives favourable approach angles for both external and light profiling operations, while the FM4 geometry channels chips away from the cutting zone to reduce re‑cutting. A 7° clearance angle helps prevent rubbing on interrupted surfaces, contributing to improved surface finish and predictable tool behaviour over longer cycles.

Application range and clamping considerations

This insert is suitable for the ISO material groups S and M, which means it is intended for heat‑resistant superalloys and stainless steel respectively. The T3 thickness and size designation (11) provide a compact, rigid contact area preferred in medium‑to‑light roughing and finishing applications where controlled chip formation is required. Proper seat cleanliness and correct clamping torque remain essential to achieve the promised repeatability and edge life in serial production.

Productivity gains through stable cutting performance

Adopting this insert supports productive turning processes by reducing unexpected tool changes and smoothing the path to consistent part quality. The coated geometry and chip control contribute to lower scrap rates and better predictability in cycle times. For operations focused on repeatability and uptime, the combination of grade, coating and geometry delivers an efficient compromise between longevity and surface integrity.

FAQ

What materials is this insert suited for?
The DCMT11T302‑FM4 WSM30S is designed for ISO groups S and M, meaning it is suited for heat‑resistant superalloys and stainless steel.

How does the FM4 chipbreaker affect machining?
The FM4 chipbreaker promotes predictable chip segmentation and evacuation; this reduces re‑cutting and supports a more consistent surface finish when machining sticky or gummy materials.

Is the 0.2 mm corner radius suitable for finishing passes?
A 0.2 mm corner radius offers a balance between edge strength and finish capability, making it appropriate for light finishing and semi‑finishing operations with stable clamping.

Can this insert be used for interrupted cuts?
Yes; the 7° clearance together with the robust grade and coating improves resistance to edge chipping under interrupted cutting conditions, provided the correct seat and clamping are used.

Which series and brand manufacture this insert?
The insert belongs to the Tiger‑tec Silver series and is supplied by Walter Tools under the designation DCMT11T302‑FM4 WSM30S.
