• Optimised for stainless steel and superalloys
• Rhombic 80° geometry with 7° clearance
• FM6 chipbreaker for reliable chip control

Coating and grade that sustain cutting-edge performance

The combination of the Tiger·tec Silver coating and the WSM20S grade provides a coated carbide surface engineered for enhanced thermal resistance and edge security during heavy-duty cuts. This formulation supports secure chip formation and reduces the tendency for built-up edge when facing the typical challenges of stainless steel and nickel-based alloys. In practice, the result is a more predictable tool life and fewer unscheduled insert changes, which contributes to improved machine uptime and lower unit production costs.

Geometry engineered for stable cutting and process reliability

With a Rhombic 80° shape, a 7° clearance angle and a 0.8 mm corner radius, the insert delivers a robust cutting edge suitable for turning applications that require a balance between edge strength and surface finish. The FM6 chipbreaker is matched to the geometry to control chip flow under variable cutting conditions, reducing the risk of entanglement and improving chip evacuation. These attributes together make the insert particularly suitable where repeatability and surface integrity are decisive for downstream processes.

Practical advantages in production: predictable results and broader material scope

The grade designation explicitly supports ISO material groups M and S, meaning the insert is designed for stainless steel as well as heat-resistant superalloys and titanium alloys. For production planners, this translates into fewer tool changes across mixed-material batches and simplified tool inventory. The insert’s performance characteristics favour operations that demand consistent dimensional accuracy and reliable surface quality, helping to meet tight tolerances with reduced rework.

Handling, compatibility and process integration

The insert is supplied in the CCMT format with the standard dimensions corresponding to the designation, enabling straightforward integration into common turning tool holders and tool systems. The moderate thickness and standardised clamping geometry facilitate quick index changes and consistent seating, which supports stable cutting parameters and reduces setup time. Technical data such as insert size and form ensure compatibility with established workshop tooling and support straightforward programming of process parameters.
