TNMG160412-RM5 WSM30S – Indexable turning insert, Tiger·tec Silver (Walter Tools)

TNMG160412-RM5 WSM30S is an indexable turning insert engineered for demanding turning of stainless steels and heat-resistant superalloys.

Tiger·tec Silver coating for improved wear resistance
Optimised RM5 chipbreaker for stable chip control
Negative 0° geometry for interrupted cuts
1.2 mm corner radius for robust cutting edges

Consistent edge life for tough materials

The combination of a coated carbide grade and Tiger·tec Silver technology delivers a balance of heat resistance and edge stability. This insert is developed for groups M and S according to ISO 513, which covers stainless steels and heat-resistant superalloys/titanium; the result is reduced tendency to build-up edge and prolonged tool life under elevated cutting temperatures. The WSM30S grade supports secure chip formation and protects the cutting edge against thermal and mechanical loads, enabling longer uninterrupted production runs and fewer tool changes.

Predictable chip control and process security

A purpose-designed RM5 chipbreaker improves chip segmentation and evacuation in both continuous and semi-continuous turning. The negative 0° geometry enhances stability in interrupted cuts and heavy engagement, keeping vibration low and surface finish consistent. With a 1.2 mm corner radius, the insert tolerates higher feed rates while maintaining a strong cutting edge, which contributes to consistent cycle times and easier process parameter standardisation across batches.

Practical application and toolset integration

Available in a triangular 60° shape with a nominal size of 16, the insert is straightforward to index and fits common turning toolholders that accept the TNMG family. The specification supports machining strategies where heat generation and chip control are critical—roughing to semi-finishing of stainless steels and superalloys. Operators benefit from the insert’s blend of edge protection and chip control, which reduces rework and improves throughput while maintaining the dimensional stability required in precision turning applications.

FAQ

What materials is this insert suitable for?
The TNMG160412-RM5 WSM30S insert from Walter Tools is specified for ISO groups M and S, meaning it is suitable for stainless steels and heat-resistant superalloys/titanium where heat resistance and edge stability are required.

How does the RM5 chipbreaker affect machining?
The RM5 chipbreaker on the Walter Tools insert improves chip segmentation and evacuation, reducing the risk of chip entanglement and supporting consistent surface quality during continuous or interrupted turning.

Is the negative 0° geometry suitable for interrupted cuts?
Yes, the negative 0° geometry increases insert stability under shock loads, making this indexable insert a reliable choice for interrupted cuts and heavy engagement scenarios.

What does the 1.2 mm corner radius mean for cutting parameters?
A 1.2 mm corner radius provides a robust cutting edge that allows higher feed rates and better resistance to edge chipping, which supports more productive roughing and semi-finishing operations with stable tool life.

Which toolholders are compatible with this TNMG insert?
The TNMG160412-RM5 WSM30S follows the TNMG family dimensions and fits standard toolholders designed for TNMG inserts; consult Metav Werkzeuge for holder recommendations and cutting-data optimisation.
