CCMT120408-FM4 WSM10S — Walter Tools turning insert, Tiger·tec Silver, rhombic 80°

The CCMT120408-FM4 WSM10S is a coated turning insert engineered for demanding applications in stainless steel and heat-resistant superalloys, combining thermal-stable coating and robust chip control for productive machining.

• Tiger·tec Silver coating for thermal stability
• Robust chip control with FM4 chipbreaker
• Rhombic 80° for versatile turning operations
• 0.8 mm corner radius for durable cutting edge

High thermal stability for long tool life

The coated grade WSM10S from the Tiger·tec Silver series is formulated to resist heat and abrasive wear when machining high-alloy materials. Its multilayer coating enhances hot-hardness and reduces flank wear under elevated cutting temperatures, which translates directly into longer operating intervals and fewer index changes. For operations involving stainless steel or heat-resistant alloys, this thermal resistance supports consistent component quality and reduced tooling costs through improved cumulative tool life.

Geometry and chip control that improve process security

The rhombic 80° insert form provides a favourable balance between approach angle and cutting force distribution, enabling stable turning and predictable tool behaviour. With a 7° clearance angle the insert minimises rubbing and heat build-up behind the cutting edge. The FM4 chipbreaker is designed to produce controllable chips in semi-finishing and finishing passes, reducing the risk of entanglement and improving surface finish. These characteristics together support reproducible cycle times and lower scrap rates in series production.

Robust edge design for steady performance

A 0.8 mm corner radius creates a resilient cutting edge that tolerates moderate interruptions and deflection, maintaining dimensional integrity on complex workpieces. The insert’s tolerance class M ensures consistent geometry across batches, simplifying tool offsets and machine set-up. The result is a dependable turning solution that reduces process variation and helps maintain target tolerances with fewer in-process adjustments.

Application guidance and process benefits

Optimised for ISO groups M and S, the insert is suitable for stainless steel as well as heat-resistant superalloys and titanium, where thermal stability and edge security are essential. The coated carbide substrate combined with the chipbreaker enables efficient material removal in demanding alloys while supporting acceptable surface quality. For best results, pair this insert with stable tooling holders and appropriate cutting parameters; modest feed increases often yield productivity gains without compromising tool life, thanks to the grade’s balanced wear resistance.

FAQ

Which materials is this insert best suited for?
The CCMT120408-FM4 WSM10S is specified for stainless steel and heat-resistant superalloys (ISO groups M and S), offering thermal stability where conventional grades would wear prematurely.

What advantages does the Tiger·tec Silver coating provide?
Tiger·tec Silver on the WSM10S grade combines wear resistance and hot-hardness to extend tool life and maintain consistent cutting performance in elevated temperature conditions.

How does the FM4 chipbreaker influence machining results?
The FM4 chipbreaker delivers controlled chip formation and improved evacuation, supporting better surface finish and reducing the risk of chip-related interruptions during turning.

For which operations is the rhombic 80° geometry suitable?
The rhombic 80° form is versatile for general turning, facing and light profiling tasks, offering a balance between strength and cutting precision for semi-finish and finish passes.

What does the 0.8 mm corner radius mean for process setup?
A 0.8 mm corner radius provides a robust edge that tolerates slight interruptions and stabilises cutting forces, which helps to maintain dimensional accuracy and extend the useful life of the insert.
