DCMT11T308-FM4 WSM30S indexable turning insert, Tiger·tec Silver – for rostfreier Stahl and superalloys | Walter Tools

The DCMT11T308-FM30S WSM30S is an indexable turning insert in rhombic 55° form, engineered for secure chip formation when machining rostfreier Stahl and heat-resistant superalloys

• Tiger·tec Silver coating for high process security
• 0.8 mm corner radius for consistent edge strength
• 7° clearance angle reduces rubbing and heat
• Optimised FM4 chipformer for stable chip control

Durable coating for long tool life and consistent results

The combination of the Tiger·tec Silver coating and the WSM30S carbide grade targets the main challenges of machining rostfreier Stahl and high-temperature alloys: poor heat conductivity and a tendency to form built-up edge. The advanced multilayer coating improves thermal resistance and reduces abrasive wear, which results in longer tool life and predictable performance under prolonged cutting. For production environments where repeatability matters, this insert supports higher process stability and fewer unplanned tool changes.

Geometry that stabilises the cut and improves surface finish

The rhombic 55° shape with a 0.8 mm corner radius and a 7° clearance angle is designed to balance edge strength and cutting action. The slightly positive clearance reduces flank rubbing and heat generation, while the corner radius provides robustness against chipping during interrupted cuts. Combined with the FM4 chipformer, the geometry promotes stable chip control, reducing the likelihood of tangling in long-turning operations and helping to maintain a consistent surface quality on the workpiece.

Productivity gains through targeted design and material coverage

This insert is optimised for machining rostfreier Stahl (M) and heat-resistant superalloys or titanium (S), offering broad applicability across demanding materials. The design aims to increase productive machining time by lowering the rate of edge failure and by producing manageable chips that simplify disposal and machining rhythm. In practical terms, the insert contributes to reduced downtime, more consistent cycle times and improved overall process economy in series production or high-mix environments.

Practical guidance for application and process integration

As an indexable turning solution, the insert suits a range of CNC lathes and turning operations where predictable chip behaviour is required. Toolholders that support DCMT geometry should be used to exploit the rhombic 55° form fully. While cutting parameters depend on machine rigidity, workpiece setup and coolant strategy, the combination of Tiger·tec Silver and the FM4 chipformer typically allows for conservative starting settings and incremental optimisation towards higher material removal rates.

FAQ

What materials are suitable for this insert?
The DCMT11T308-FM4 WSM30S insert is designed primarily for rostfreier Stahl (M) and high-temperature alloys such as titanium and superalloys (S), providing stable cutting under demanding conditions.

Which chipformer does the insert use and why does it matter?
The insert features the FM4 chipformer; this geometry promotes stable chip control, reducing tangling and improving process reliability when turning ductile or heat-resistant materials.

How does the Tiger·tec Silver coating benefit production?
Tiger·tec Silver on the WSM30S grade increases thermal resistance and wear protection, which leads to longer edge life and more consistent results in serial production.

Is this insert compatible with standard DCMT toolholders?
Yes, the insert conforms to DCMT geometry and is compatible with toolholders that accept DCMT inserts; correct clamping and seat condition are essential for optimal performance.

Can this insert be used for interrupted cuts or profiling?
The 0.8 mm corner radius and robust grade make the insert suitable for light interruptions and profiling where edge strength is required; application specifics should be validated with trial cuts.
