CNMG160608-RM5 WSM20S indexable turning insert — Tiger·tec Silver grade for stainless steels & superalloys (Walter Tools)

The CNMG160608-RM5 WSM20S is an indexable turning insert engineered for heavy-duty and heat‑generating materials, offering a coated carbide grade and a geometry optimised for secure chip control and edge stability.

• Tiger·tec Silver coating for high wear resistance
• Optimised RM5 chipbreaker for secure chip control
• Negative 0° rake for stable cutting performance
• 0.8 mm corner radius for improved edge strength

Durable performance for difficult-to-machine alloys

The combination of the WSM20S grade and the Tiger·tec Silver coating delivers enhanced wear resistance and consistent edge behaviour when machining demanding materials. This coated carbide is formulated to withstand thermal and mechanical loads common in machining stainless steels and superalloys, so tool life becomes more predictable and unplanned tool changes are reduced. For production environments where repeatability matters, this insert supports process stability by reducing flank wear progression and maintaining a reliable cutting edge over extended cycles.

Stable cutting and efficient chip control

The integrated RM5 chipbreaker is designed to produce controllable chip forms under challenging cutting conditions, which lowers the risk of built-up edge and reduces interruption to automated turning cycles. Combined with the negative 0° rake, the geometry increases cutting-edge strength, improving resistance to shock and vibration during interrupted cuts. As a result, cycle times can be shortened and surface integrity is easier to maintain, offering a direct productivity advantage for serial machining of tougher materials.

Flexible geometry that balances strength and finish

The rhombus 80° configuration with a 0.8 mm corner radius provides a robust cutting edge while still enabling acceptable surface finishes in many turning operations. The insert’s format allows for stable axial and radial engagement, making it suitable where both material removal and component quality are required. Because the geometry emphasises edge robustness, finishing passes benefit from consistent contact pressure and reduced tendency for edge rounding, which supports tighter dimensional control in production.

Practical integration into machining processes

The designation and format of this CNMG insert follow common ISO conventions, simplifying inventory management and toolholder selection for established turning systems. The CNMG160608-RM5 WSM20S insert is intended for integration into standard CNMG toolholders and can be specified where a coated, process-secure solution is needed. For precise cutting parameters or tailored recommendations for specific stainless steels or superalloys, the technical team at Metav Werkzeuge can provide application data to match feed, speed and depth of cut to the grade and chipbreaker combination.
