CCMT09T302-FW4 WSM20S indexable turning insert — Tiger·tec Silver grade, FW4 chipbreaker, Walter Tools

A CCMT09T302-FW4 WSM20S indexable turning insert designed for machining stainless steels and heat‑resistant superalloys in demanding turning operations

• Tiger·tec Silver coating for edge stability
• Optimised FW4 chipbreaker for secure chip control
• Rhombic 80° geometry with 0.2 mm corner radius
• Suitable for stainless steels and superalloys

Reliable cutting performance on stainless steels and superalloys

The combination of the WSM20S grade and Tiger·tec Silver coating provides a balance of heat resistance and wear protection that supports consistent cutting performance in materials classified under ISO group M (stainless steels) and S (heat‑resistant superalloys and titanium). The specialised coated carbide composition favours stable chip formation and helps to mitigate built‑up edge, which is a common challenge when turning high‑toughness materials. This results in predictable tool life and reduced variability in process outputs, supporting production planning and quality control.

Geometry and chip control that enhance surface quality

The FW4 chipbreaker is engineered to produce controllable, segmented chips in a variety of cutting conditions; combined with the rhombic 80° form and a 0.2 mm corner radius, the insert offers a compromise between robustness and fine surface finish. These geometric features help to maintain a reliable cutting edge and reduce the risk of chatter when used with appropriate machine settings. For operators less familiar with chipbreaker function: it directs chip flow and breaks chips into manageable lengths, improving evacuation and reducing tool and workpiece damage.

Process efficiency and application suitability

With a T3 insert thickness and a medium tolerance class, this indexable insert is suitable for stable, repeatable turning operations where durability and productivity matter. The grade is optimised for demanding applications such as bar turning, face and light profiling of stainless components, and hard‑to‑machine alloys where edge stability and thermal resistance improve throughput. Selecting the correct insert geometry and cutting data will enable lower downtime, fewer regrinds and more consistent batch quality, offering a tangible contribution to overall machining economics.

FAQ

What materials is this insert suitable for?
The WSM20S grade is formulated for stainless steels (ISO M) and can also be applied to heat‑resistant superalloys (ISO S) depending on the geometry and cutting conditions.

How does the FW4 chipbreaker improve machining?
The FW4 chipbreaker shapes and breaks chips into manageable segments, improving evacuation and reducing the risk of damage to the insert or workpiece during turning.

What does the 0.2 mm corner radius mean for performance?
A 0.2 mm corner radius provides a balance between edge strength and surface finish: it gives sufficient durability for continuous cuts while enabling a finer surface on the workpiece.

Is this insert suitable for finishing and roughing operations?
The insert’s geometry and Tiger·tec Silver coating make it versatile; with adjusted cutting data it can be used for light finishing and steady medium‑duty turning, prioritising edge stability and repeatability.

Can this insert be used on titanium alloys?
Depending on the component and cutting strategy, the grade can be applied to titanium (ISO S) where thermal and edge stability are required; optimised parameters and coolant strategy are recommended.
