DCMT11T308-FW4 WSM30S indexable turning insert — Tiger·tec Silver, for stainless steels and superalloys (Walter Tools)

DCMT11T308-FW4 WSM30S is an indexable turning insert engineered for secure chip control and consistent edge life when machining demanding materials such as stainless steels and heat‑resistant superalloys.

• Tiger·tec Silver coating for thermal stability
• FW4 chipbreaker for reliable chip control
• 55° rhombic geometry for versatile turning
• 0.8 mm corner radius for robust edges

High‑productivity coating for heat‑critical materials

The WSM30S grade, based on Tiger·tec Silver, couples a wear‑resistant coating with a coated carbide substrate to maintain edge integrity under elevated temperatures. This results in extended tool life and reduced dressing frequency when turning materials that generate heat and tend to work‑harden, such as stainless steels and nickel‑based alloys. The combination of coating technology and substrate enables stable cutting conditions and improved process security in continuous and interrupted cuts.

Geometry and chip control that lower cycle times

A 55° rhombic form with a 7° clearance angle provides a balance between accessibility in turning operations and edge strength. The FW4 chipbreaker is designed to produce short, controllable chips in medium to heavy cuts, reducing the need for frequent machine stoppages. Where machining efficiency matters, the geometry and chip‑forming features of this insert contribute directly to shorter cycle times and higher net output per shift.

Robust edge preparation for consistent surface finish

The 0.8 mm corner radius supports a stable cutting edge that resists chipping and enables repeatable surface quality across batches. Combined with the coated carbide grade, this preparation reduces microchipping and minimises the risk of built‑up edge when facing stainless steels. As a result, secondary operations for surface correction are less frequent, supporting a leaner production flow and predictable part tolerance attainment.

Versatile use and application guidance

Designed for the machining of materials classified as M (stainless steels) and S (heat‑resistant superalloys and titanium), this insert suits workshops seeking a single‑grade solution for mixed production runs. The insert’s designation and chipbreaker selection make it appropriate for conventional lathes and CNC turning centres. For specific cutting data, insert seat requirements and optimal feed‑speed maps, the Metav Werkzeuge technical team can provide tailored recommendations to match machine rigidity and workpiece characteristics.

FAQ

What materials is this insert suited for?
The DCMT11T308-FW4 WSM30S insert is intended for stainless steels (M) and heat‑resistant superalloys/titanium (S), offering thermal stability and controlled chip formation for these groups.

How does the Tiger·tec Silver coating benefit production?
The Tiger·tec Silver coating improves thermal resistance and wear behaviour, which helps maintain a stable cutting edge and extends the service life of the insert under high‑temperature conditions.

Which chipbreaker is fitted and what does it do?
This grade uses the FW4 chipbreaker, designed to produce controlled, short chips in medium to heavy turning operations and to reduce interruptions caused by long, unmanageable swarf.

Can the insert be used on CNC turning centres and conventional lathes?
Yes; the insert’s geometry and chip control features make it suitable for both CNC turning centres and conventional lathes, provided the correct toolholder and cutting data are applied.
