CNMG160612-MM5 WSM20S turning insert, Tiger·tec Silver – engineered for stainless steel and superalloys | Walter Tools

The CNMG160612-MM5 WSM20S is a negative‑rake, 80° rhombic turning insert designed for heavy and heat‑generating materials such as stainless steels and superalloys

• Tiger·tec Silver coated WSM20S grade
• Optimised for stainless steel and superalloys
• 0° negative rake for robust cutting
• 1.2 mm corner radius for edge stability

High thermal stability and longer tool life for demanding alloys

The Tiger·tec Silver coating combined with the WSM20S carbide substrate improves wear resistance and thermal stability, helping to maintain cutting edge integrity under high temperatures. For materials that tend to work‑harden or generate heat—notably stainless steels and superalloys—this surface technology supports predictable wear behaviour and fewer index changes. In practice this means longer intervals between insert changes and more consistent part quality, which contributes directly to improved process efficiency and lower overall machining costs.

Geometry and edge design that prioritise process security

The rhombic 80° shape with a 0° negative rake produces a robust cutting edge suited to interrupted cuts and heavier feeds; the 1.2 mm corner radius increases edge strength and allows for stable chip formation at higher feeds. The integrated MM5 chipbreaker controls chips on difficult‑to‑machine alloys, reducing the risk of entanglement and aiding evacuation. Translating these features into operational benefit: fewer stoppages, reduced secondary operations to clear chips, and more reliable cycle times on production runs.

Application guidance for efficient implementation

The insert is intended for turning operations in which material ductility and heat generation can compromise edge life. The designation CNMG160612‑MM5 indicates the geometry and chipbreaker combination suitable for both roughing and semi‑finishing, depending on insert seat and machine rigidity. When machining rostfreier Stahl or heat‑resistant alloys, modest increases in coolant flow and appropriate feed selection preserve the Tiger·tec Silver coating performance. For tailored cutting data and holder recommendations, refer to technical sheets or seek advice from Metav Werkzeuge to match the insert to the specific turning task.

FAQ

Which materials is this insert best suited for?
The CNMG160612‑MM5 WSM20S is formulated for rostfreie Stähle and heat‑resistant superalloys (groups M and S) where thermal stability and controlled chip formation are critical.

How does the MM5 chipbreaker influence performance?
The MM5 chipbreaker on this Walter Tools insert improves chip control for ductile and work‑hardening materials, aiding evacuation and reducing the risk of chip rework or surface damage.

Can this geometry be used for both roughing and finishing?
Yes, the 80° rhombic shape with a 1.2 mm corner radius and negative rake provides robustness for roughing and consistent edge life for semi‑finishing; final surface requirements determine the best feed and depth settings.

What benefit does the Tiger·tec Silver coating provide?
Tiger·tec Silver enhances wear resistance and heat tolerance, which helps maintain cutting edge geometry under elevated temperatures common when machining stainless steels and superalloys.

Is the CNMG160612‑MM5 WSM20S compatible with standard CNMG toolholders?
The ISO designation CNMG160612‑MM5 indicates standard interface geometry compatible with CNMG holders; ensure the holder matches the insert thickness and seat type for optimal clamping and runout.
