Increased cutting reliability for tough materials

The combination of Tiger·tec Silver technology and the WSM20S grade gives this insert high thermal resilience and wear resistance, which is especially beneficial when machining stainless steels and heat‑resistant superalloys. The coating reduces friction and thermal loading at the cutting edge, resulting in longer tool life and fewer interruptions for index changes. As a result, cycle times are more predictable and process capability improves — important factors for batch production and precision components. The use of a coated carbide substrate ensures a balance between edge toughness and hardness for demanding applications.

Geometry engineered for surface quality and repeatability

The Rhombic 80° shape combined with a 7° clearance and a corner radius 0.4 mm reduces cutting forces and supports a consistent cutting engagement. This geometry is well suited to general turning and finishing passes where surface integrity matters; the small radius helps achieve good contact conditions for tight tolerances while maintaining edge stability. The insert’s thickness 0.4 mm and tolerance class M deliver repeatable seating in the toolholder, which simplifies process set‑up and reduces variability between insert changes.

Productivity gains through chip control and process security

The integrated MM4 chipformer is optimised for secure chip breaking and evacuation under the high temperatures typical when machining tough alloys. Reliable chip formation lowers the risk of built‑up edge and reduces rework caused by edge deterioration. For production environments, this translates into higher effective material removal rate, fewer tool interventions and improved overall equipment efficiency. Walter Tools’ engineering focus on process security ensures the grade and geometry work together to reduce unplanned downtime and improve batch consistency.

FAQ

What materials is this insert intended for?
The CCMT120404-MM4 WSM20S insert is specified for stainless steels (ISO group M) and heat‑resistant superalloys/titanium (ISO group S), making it suitable for components that demand thermal and edge stability.

How does the Tiger·tec Silver technology benefit machining?
Tiger·tec Silver on the WSM20S grade improves heat resistance and wear performance, which helps maintain a stable cutting edge and extends indexable insert life under high thermal loads.

Why choose a Rhombic 80° insert for turning tasks?
The Rhombic 80° form combines accessibility for shoulder and profile cuts with a favourable edge angle for general turning, delivering consistent surface finish and flexible operation windows.

What role does the MM4 chipformer play in process reliability?
The MM4 chipformer promotes controlled chip breaking and evacuation during cutting, reducing the risk of built‑up edge and helping to secure uninterrupted production when machining difficult alloys.
