CCMT060208-FM4 WSM20S turning insert – Walter Tools (Tiger·tec Silver, for rostfreier Stahl and superalloys)

CCMT060208-FM4 WSM20S is an indexable turning and boring insert designed for heavy-duty machining of rostfreier Stahl and heat-resistant alloys, offering stable edges and reliable chip control in challenging conditions

• Tiger·tec Silver coating for heat resistance
• Optimised for rostfreier Stahl and superalloys
• Rhombic 80° geometry for versatile turning

Consistent performance where heat and adhesion are critical

The CCMT060208-FM4 WSM20S insert combines a coated carbide grade with a specialised chipbreaker to maintain stable chip formation even under high thermal load. The Tiger·tec Silver technology increases thermal resistance and reduces flank wear, which translates into longer effective tool life and fewer interruptions for tool changes. For operations that involve hard-to-cut materials, such as rostfreier Stahl and nickel-based alloys, this behaviour reduces the risk of built-up edge and improves process reliability, enabling steadier cycle times and reduced scrap rates.

Geometry that supports precision and process stability

The Rhombic 80° shape with a 0.8 mm corner radius and 7° relief provides a balance between cutting edge strength and accessibility into tight profiles. This geometry offers a secure cutting edge for facing and turning operations while allowing the insert to be used in a variety of toolholders and setups. The moderate corner radius helps to distribute cutting forces and reduces the likelihood of premature chipping, resulting in improved surface finish and repeatable dimensional accuracy for serial production.

Chip control and cutting behaviour explained

The FM4 chipbreaker is engineered to direct and fragment chips reliably across a range of feeds, supporting secure evacuation in interrupted cuts and continuous turning. Good chip control minimises rework and tool collisions, which improves shop-floor safety and machine uptime. Combined with the coated carbide grade WSM20S, the insert addresses the principal machining challenges posed by materials that produce long, stringy chips or that create elevated cutting temperatures, keeping the process both productive and more predictable.

Practical integration into machining processes

Adopting this insert in a machining cell favours process stability: the coated grade and geometry reduce the need for frequent tool index changes, while compatibility with standard CCMT toolholders simplifies logistics. Selection of cutting parameters should consider the material group (rostfreier Stahl or superalloys) and the intended operation; the insert’s traits favour medium to heavy cuts where edge security and heat resistance are priorities. For users seeking to optimise cycle time and tool economy, the combination of coating, chipbreaker and robust geometry offers measurable gains in throughput.

FAQ

What materials is this insert best suited for?
The CCMT060208-FM4 WSM20S insert from Walter Tools is optimised for rostfreier Stahl and for heat-resistant superalloys, providing stable cutting edges and reliable chip control in these material groups.

Can the insert be used for both roughing and finishing?
Yes, the combination of Rhombic 80° geometry and a 0.8 mm corner radius supports both medium roughing cuts and finishing passes, depending on chosen cutting parameters and toolholder setup.

What benefits does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating increases thermal resistance and surface hardness, which reduces flank wear and improves tool life when machining demanding materials such as rostfreier Stahl.

Is the FM4 chipbreaker suitable for interrupted cuts?
The FM4 chipbreaker is designed for secure chip formation and evacuation, making it appropriate for interrupted cuts and for operations where consistent chip control is required.

Which toolholders are compatible with this insert designation?
The CCMT060208-FM4 geometry is compatible with standard toolholders designed for CCMT-style rhombic 80° inserts; ensure the seat and clamping match the CCMT specification.

How does the insert support process reliability in production runs?
By combining a heat-resistant coating, a robust chipbreaker and a strong corner radius, the insert reduces tool wear and the risk of built-up edge, contributing to fewer tool changes and more consistent cycles in serial production.
