CNMG160612-MU5 WSM20S indexable turning insert — rhombic 80°, 1.2 mm corner radius (Walter Tools)

The CNMG160612-MU5 WSM20S is an indexable turning insert engineered for secure machining of rostfreier Stahl and high‑temperature alloys, offering high edge stability through the Tiger‑tec Silver coating.

• Tiger‑tec Silver coating for heat resistance
• Optimised MU5 chipbreaker for stable chips
• Rhombic 80° form with 1.2 mm corner radius

Reliable thermal stability for tough materials

The Tiger‑tec Silver coating paired with the WSM20S carbide grade gives the insert a marked advantage when tackling materials that generate heat and strain the cutting edge. For machining rostfreier Stahl and Superalloys, the coating reduces adhesion and supports a consistent cutting edge, which translates into extended tool life and fewer index changes. The result is a more predictable process with reduced scrap rates and higher uptime, making the insert a rational choice where process stability and component quality are priorities.

Geometry engineered for strength and repeatability

The rhombic 80° profile and a 1.2 mm corner radius deliver a balance between robustness and finishing capability. The negative rake angle of 0° increases resistance to edge chipping under interrupted or heavy cuts, while the CNMG format ensures secure clamping and repeatable seating in standard toolholders. Together these features maintain dimensional accuracy during longer cycles and simplify tool management in production environments where consistency and repeatability matter.

Efficient chip control and reduced machining costs

The MU5 chipbreaker is optimised for controlled chip formation across ISO M and S workpiece groups. Stable chips reduce recutting and improve surface integrity, enabling higher cutting parameters and shorter cycle times without sacrificing component finish. This efficiency contributes to lower unit costs over batch runs and supports leaner production by minimising tool changes and secondary operations.

Easy adoption into existing workflows

Available in the common CNMG size, this insert integrates seamlessly with standard tool bodies and changeover procedures. The clear grade designation and series (Tiger‑tec Silver, WSM20S) aid rapid tooling decisions and minimise setup time. Whether used for roughing heavy sections or finishing demanding rostfreier Stahl parts, the insert provides a straightforward upgrade path for workshops seeking improved process security with minimal retraining.
