TNMG160404-MU5 WSM20S indexable turning insert — Triangle 60°, 0.4 mm corner radius, Walter Tools

A TNMG160404-MU5 WSM20S indexable turning insert engineered for reliable chip control and extended tool life when machining stainless steel and heat-resistant superalloys in demanding turning operations

• Tiger·tec Silver coating for heat resistance
• Stable cutting edge in stainless steel
• MU5 chipbreaker for consistent chip control
• Triangular 60° form for versatile turning

Higher productivity when machining stainless steel and superalloys

The coated WSM20S grade from the Tiger·tec Silver family is developed for materials that generate heat and tend to form long or sticky chips. With a defined corner radius of 0.4 mm, a negative 0° rake angle and the MU5 chipbreaker geometry, the insert promotes stable chip formation and helps avoid built-up edge; this reduces rework and improves process reliability. The combination of coating technology and substrate hardness extends cutting edge life under thermal and mechanical load, which directly contributes to measurable increases in machining throughput and lower tool consumption.

Consistent surface finish and predictable tool life for turning processes

A precise tolerance class M and the triangular 60° insert form make this insert suitable for a range of turning tasks, from light finishing to more demanding profiles. The MU5 chip control geometry is designed to subdivide and evacuate chips efficiently, which supports consistent surface quality on the workpiece and reduces downtime for manual chip management. For engineers and production planners, this means fewer interruptions and a more predictable replacement interval for indexable inserts, improving overall shop-floor efficiency and process planning.

Simple integration into existing toolchains and process support

The geometrical data and coating characteristics of this insert allow straightforward adaptation into standard toolholders and tool programmes. As the grade targets stainless steel and heat-resistant alloys, recommended cutting speeds and feeds differ from those for general steels; Metav Werkzeuge can supply tested cutting data and set-up recommendations tailored to the intended application. This reduces trial-and-error at the machine and helps reach the expected component tolerances faster, while maintaining reproducible results across production batches.

FAQ

Which materials are best suited to this insert?
The TNMG160404-MU5 WSM20S is primarily designed for stainless steel and high-temperature superalloys (material groups M and S), where heat resistance and edge stability are critical.

How does the Tiger·tec Silver coating improve performance?
The Tiger·tec Silver coating increases thermal resistance and wear protection, supporting longer edge life and stable performance in operations with elevated cutting temperatures.

What is the benefit of the MU5 chipbreaker on this insert?
The MU5 chipbreaker promotes controlled chip segmentation and evacuation, reducing the risk of entanglement and improving surface finish during turning.

Is this insert compatible with standard TNMG toolholders?
The insert follows the TNMG160404 ISO form and fits holders designed for TNMG inserts with triangular 60° geometry; ensure correct seat and clamping for optimal performance.

How does the 0.4 mm corner radius affect machining?
A 0.4 mm corner radius balances edge strength and surface quality: it supports a robust cutting edge for interrupted cuts while still allowing fine surface results in finishing passes.
