TNMG160412-MU5 WSM20S indexable turning insert for stainless steels and superalloys — Walter Tools

A TNMG160412-MU5 WSM20S indexable turning insert designed to deliver consistent chip control and edge stability when machining rostfreie Stähle and heat‑resistant superalloys.

• Tiger‑tec Silver coated carbide grade WSM20S
• Triangle 60° insert with 1.2 mm corner radius
• MU5 chipbreaker for controlled chip formation
• Negative 0° relief for robust cutting action

Optimised grade and coating for difficult materials

The Walter WSM20S grade, part of the Tiger‑tec Silver family, combines a wear‑resistant coating with a coated‑carbide substrate to extend tool life when machining stainless steels and nickel‑based alloys. The selected grade supports stable cutting edges and reduced built‑up edge, which in turn improves process reliability. For production environments processing tough alloys, this results in fewer tool changes and more predictable spindle time, enhancing throughput and lowering cycle‑time variability.

Geometry and chip control that stabilise the cut

The triangular 60° geometry with a 1.2 mm corner radius and the MU5 chipbreaker create a balanced profile for finishing and medium turning operations. The negative 0° relief provides a robust cutting face that resists edge chipping under interrupted cuts or heavy radial engagement. Explained simply: the corner radius reduces notch sensitivity and the chipbreaker shapes chips to evacuate reliably, so operators observe improved surface finish and reduced risk of machine stoppages due to clogged chip evacuation.

Production advantages and application fit

Designed for industrial turning, the insert supports consistent results across batches of rostfreie Stähle and heat‑resistant superalloys. The combination of grade, chipbreaker and geometry yields a cost‑effective solution by extending edge life and maintaining surface integrity, which lowers rework rates. In practise, this means fewer tool changeovers per shift and steadier part quality for components that demand tight surface specifications or repeatable dimensional control.

FAQ

What materials is this insert suitable for?
The TNMG160412‑MU5 WSM20S insert from Walter Tools is specified for rostfreie Stähle and heat‑resistant superalloys (ISO groups M and S), providing good edge stability when machining these demanding materials.

What role does the MU5 chipbreaker play?
The MU5 chipbreaker on the Walter insert shapes and breaks chips reliably to improve evacuation and surface finish, reducing the risk of chip entanglement during continuous turning operations.

Why choose a negative 0° relief angle?
A negative 0° relief provides a robust cutting edge for the insert, making the geometry more resistant to edge chipping under heavy cuts or interrupted machining, which supports process stability in production.

How does the 1.2 mm corner radius affect production?
The 1.2 mm radius increases notch resistance and distributes cutting forces, which helps to improve surface quality and extend tool life in finishing to medium turning.

Is this insert part of a recognised coating family?
Yes, the insert belongs to the Tiger‑tec Silver family; the coated‑carbide construction is intended to enhance wear resistance and thermal stability during machining of difficult alloys.
