TNMG160412-MM5 WSM20S indexable turning insert, triangle 60°, Tiger·tec Silver – Walter Tools

A TNMG160412-MM5 WSM20S indexable turning insert designed for heavy‑duty cutting of rostfreiem Stahl (stainless steels) and heat‑resistant superalloys, offering a negative 0° rake and a 1.2 mm corner radius for robust edge life

• TNMG160412-MM5 format, triangle 60°
• Tiger·tec Silver coating WSM20S grade
• Corner radius 1.2 mm for stable edges
• Suitable for stainless steels and superalloys

Reliable performance with high thermal stability

The insert combines a coated carbide grade from the Tiger·tec Silver family with the WSM20S specification to deliver consistent cutting performance where temperatures and stickiness challenge tool life. The combination of coating technology and substrate provides enhanced resistance to abrasion and built‑up edge, which results in longer productive cutting intervals and fewer insert changes. This leads to measurable process stability and reduced downtime in serial turning operations on stainless steels and heat‑resistant alloys.

Consistent chip control and edge security for tough materials

Equipped with the MM5 chipbreaker and a negative 0° rake, the insert promotes predictable chip formation under high thermal loads typical of inox and superalloy machining. The corner radius 1.2 mm supports a robust cutting edge suitable for semi‑roughing to finishing passes, helping to maintain dimensional consistency and surface quality. For engineers requiring reproducible results, these design choices reduce the risk of edge failure and support higher metal removal rates without compromising component integrity.

Geometry and handling that speed setup and interchange

The triangle 60° configuration provides three usable corners per insert, improving tool utilisation and lowering tooling consumption per workpiece. The standard TNMG form factor allows direct fitment into common turning toolholders, simplifying stock management and changeover. The insert thickness and form promote stable clamping and accurate seating, which aids repeatable setups and contributes to reduced cycle time in multi‑shift environments.

Application guidance and process benefits

Intended primarily for ISO groups M and S, the grade is optimised for rostfreiem Stahl and heat‑resistant superalloys and titanium where thermal and adhesion challenges occur. In practice, this results in improved flank wear behaviour and more reliable surface finishes on components that demand high consistency. If a reduced cutting force or different surface requirement is needed, consider complementary geometries or alternative grades within the Tiger·tec Silver series to balance economy and finish.
