TNMG160408-NMS WSM30S — Indexable turning insert, Tiger‑tec Silver (Walter Tools)

The TNMG160408-NMS WSM30S is an indexable turning insert designed for heavy-duty finishing and semi-finishing of rostfreier Stahl and high-temperature alloys, featuring a triangular 60° shape and an optimised chipbreaker.

• Tiger‑tec Silver coating for thermal stability
• NMS chipbreaker for controlled chip formation
• For rostfreier Stahl and superalloys
• Triangular 60° form, 0.8 mm corner radius

Higher throughput on demanding materials

The Tiger‑tec Silver coating combined with the WSM30S grade provides enhanced heat resistance and edge security when machining tough alloys. This results in a more stable cutting process and reduced flank wear, which in turn supports longer tool life and fewer insert changes. The coated cemented carbide structure is engineered to reduce built-up edge and maintain surface quality under thermally demanding conditions when cutting rostfreier Stahl and heat-resistant superalloys.

Predictable chip control and process reliability

The dedicated NMS chipbreaker is designed to shape and control chips across a wide range of feeds and depths of cut. Controlled chip formation lowers the risk of entanglement, improves evacuation from the cutting zone and reduces machine downtime caused by chip-related interruptions. The 0° negative rake geometry contributes to a robust cutting edge that resists chipping under intermittent cuts, enhancing overall process reliability and repeatability.

Geometry that balances productivity and surface finish

The triangular 60° insert form provides three usable cutting corners, allowing multiple indexings per insert and therefore economical utilisation. A 0.8 mm corner radius supports consistent surface finish without excessive cutting forces, while the tolerance class M ensures dimensional accuracy for repeatable set-ups. These geometric characteristics combine to yield efficient material removal with a stable balance between productivity and part quality.

Application scope and easy integration into workflows

Specified for the ISO material groups S / M, this insert is especially suited to machining superalloys and rostfreier Stahl where heat generation and material toughness challenge the cutting edge. The designation and chipbreaker choice make the insert appropriate for finishing and semi-finishing operations on rotating parts, from smaller components to larger shafts, depending on toolholder selection. Compatibility with standard clamping systems and the insert’s robust design simplify process implementation in both single- and multi-shift production environments.

FAQ

What materials is this insert best suited for? The TNMG160408-NMS WSM30S is optimised for rostfreier Stahl and heat-resistant superalloys (ISO groups M and S), delivering secure chip formation and edge stability under thermal stress.

Which chipbreaker is fitted and what does it do? The insert features the NMS chipbreaker; it controls chip geometry to improve evacuation and reduce the chance of chip-related interruptions during turning operations.

How many usable cutting edges does the triangular shape provide? The triangular 60° form offers three cutting corners per insert, enabling multiple re-indexings and economical utilisation before replacement.

What does the 0.8 mm corner radius mean for surface finish? A 0.8 mm corner radius provides a compromise between strength and finish: it supports robust cutting at moderate feeds while helping to achieve a consistent surface quality.

Is the insert compatible with standard toolholders? The TNMG geometry is a common indexable insert format and fits matching holders for TNMG-style inserts; toolholder selection should correspond to the negative-rake execution and intended cutting parameters.
