CCMT120408-FM4 WSM30S indexable insert, rhombic 80° geometry, Tiger·tec Silver – Walter Tools

The CCMT120408-FM4 WSM30S is a rhombic 80° indexable insert designed for productive turning and boring of stainless steels and heat‑resistant superalloys, featuring a Tiger·tec Silver coated grade for enhanced thermal and edge performance

• Tiger·tec Silver coating for high thermal stability
• Optimised FM4 chipbreaker for secure chip control
• Rhombic 80° geometry for versatile turning and boring
• 0.8 mm corner radius for improved edge strength

Sustained performance with demanding materials

The coated WSM30S grade, part of the Tiger·tec Silver series, is engineered for materials that generate heat and resist chip flow. This configuration promotes controlled cutting at elevated temperatures, reducing the risk of built‑up edge and premature flank wear. For applications categorised under ISO group M (stainless steels) and S (superalloys/titanium), the insert’s coating and carbide substrate combine to improve thermal resistance and maintain a stable cutting edge, resulting in fewer tool changes and more predictable cycle times.

Predictable chip control and superior surface quality

The FM4 chipbreaker is optimised for secure chip formation and evacuation in tough machining scenarios. Together with the rhombic 80° geometry and a 0.8 mm corner radius, the insert balances edge strength with surface finish: the radius enhances durability on interrupted cuts while the chipbreaker reduces chatter and improves swarf handling. These characteristics help to achieve a consistent surface quality with reduced manual rework and less scrap, particularly in semi‑finishing and finishing passes.

Adaptable geometry for a range of turning tasks

Encoded as CCMT120408-FM4, the insert format suits common toolholders and is readily integrated into standard turning and boring setups. The rhombic 80° shape provides good access for profiling and external turning, while the 7° clearance angle supports stable engagement and reduced rubbing. This versatility allows the component to be used across a variety of production tasks, from single‑piece prototypes to repetitive batch work, improving inventory flexibility and simplifying tooling choices on the shop floor.

Process stability and extended tool life

Produced by Walter Tools and specified in a tolerance class M, the insert supports repeatable performance in demanding environments. The combination of a wear‑resistant coated grade and an optimised chip control geometry contributes to longer edge life and stable dimensional results over successive parts. For manufacturers seeking to raise productivity and reduce downtime, the insert offers a reliable balance between cutting efficiency and predictable maintenance intervals, supporting leaner production flows and higher first‑pass yield.

FAQ

What materials is this insert suitable for?
The CCMT120408-FM4 WSM30S insert is specified for stainless steel (ISO group M) and for heat‑resistant superalloys and titanium (ISO group S), benefiting from the Tiger·tec Silver coating for thermal resistance.

How does the FM4 chipbreaker affect machining?
The FM4 chipbreaker on the CCMT120408-FM4 promotes controlled chip formation and evacuation, improving swarf control and surface finish in demanding cutting conditions.

What does the 0.8 mm corner radius provide?
A 0.8 mm corner radius increases edge strength and resistance to chipping on interrupted or heavy cuts while still allowing a good surface finish in finishing passes.

Is this insert compatible with standard CCMT toolholders?
Yes, the CCMT120408-FM4 geometry follows standard CCMT specifications and is compatible with typical CCMT indexable turning toolholders for turning and boring operations.

Can this insert improve process stability in series production?
The combination of the WSM30S grade and Tiger·tec Silver coating enhances edge life and repeatability, contributing to improved process stability and fewer tool swaps in serial manufacturing.
