Longer tool life through advanced coating and substrate

The insert’s combination of Tiger·tec Silver technology and coated carbide substrate delivers tangible advantages in durability and process stability. The WSM20S grade is specifically engineered for materials that promote built-up edge and high temperatures; this reduces frequent tool changes and supports higher metal removal rates. In practice, the coating improves wear resistance while the substrate maintains edge strength, resulting in fewer interruptions and more predictable production cycles.

Consistent chip control and secure machining of difficult alloys

Equipped with the FM4 chipbreaker, the geometry produces short, controllable chips when machining stainless steel and heat‑resistant alloys, which otherwise tend to form long, stringy swarf. The optimised chip former and the insert’s design minimise tool clogging and enhance surface finish, making the component suitable for serial production where reproducibility and operator safety are priorities.

Geometry that supports process reliability and versatility

The rhombic 80° configuration and 0.2 mm corner radius provide a balance between strength and accessibility for internal and external operations. A 7° clearance angle reduces rubbing and thermal load at the cutting edge, while the standard size and thickness facilitate straightforward integration into common tool holders. These geometric choices translate into stable cutting forces and longer edge retention, which together improve throughput and part quality.

FAQ

What materials is the CCMT09T302‑FM4 WSM20S best suited for?
The CCMT09T302‑FM4 WSM20S is optimised for machining stainless steel and heat‑resistant superalloys (ISO groups M and S), offering stable chip formation and enhanced edge life.

How does the Tiger·tec Silver technology benefit production?
Tiger·tec Silver improves wear resistance and thermal stability on the CCMT09T302‑FM4 WSM20S, which increases tool life and reduces the frequency of insert changes during continuous or high‑load operations.

What does the FM4 chipbreaker achieve in practice?
The FM4 chipbreaker on this insert controls chip shape and evacuation for safer, cleaner machining, particularly when processing tough, ductile materials such as stainless steel.

Is the insert compatible with standard tool holders?
The insert follows common dimensional standards for its form and size (Rhombus 80°, size 09, thickness T3), enabling straightforward use in compatible indexable tool holders in turning and drilling setups.

What advantages does the 0.2 mm corner radius provide?
A 0.2 mm corner radius increases edge robustness compared with a sharp corner, improving resistance to chipping while maintaining acceptable surface finish for general turning and boring tasks.
