TNMG160408-MM5 WSM30S turning indexable insert — Tiger·tec Silver, negative 0° relief (Walter Tools)

TNMG160408-MM5 WSM30S is a triangular 60° indexable insert designed for robust turning of difficult-to-machine alloys, especially rostfreier Stahl and high-temperature superalloys.

• Tiger·tec Silver coating technology
• WSM30S grade for tough alloys
• MM5 chipbreaker for predictable chips
• 60° triangle with 0.8 mm corner radius

High-performance grade for difficult materials

The WSM30S grade, part of the Tiger·tec Silver family, is a coated carbide composition developed for heavy-duty applications. Its formulation promotes stable cutting-edge behaviour when machining rostfreier Stahl and heat-resistant superalloys, where conventional grades struggle with build-up and edge wear. The coating reduces adhesion and improves thermal resistance, which in turn lengthens edge life and reduces downtime. In practice, this means fewer insert changes and a steadier output in batch production or continuous turning operations.

Geometry designed for stability and repeatability

The triangular 60° shape and 0.8 mm corner radius combine to deliver a strong, robust cutting edge that tolerates interrupted cuts and moderate depths of cut. The insert’s negative 0° relief produces a stable cutting action that reduces vibration and supports a consistent surface finish on workpieces. For shop floors seeking repeatable results, this geometry reduces the risk of chipping on heavy cuts and provides a dependable baseline for fixture and toolholder selection.

Chip control that supports process security

Equipped with the MM5 chipbreaker, the insert encourages short, manageable chips when turning sticky or gummy materials. Controlled chip formation improves machining safety and minimises secondary operations such as manual chip clearing. The chipbreaker design also helps to maintain a steady contact zone, which supports constant cutting forces and reduces the likelihood of unplanned toolstop events—an important factor for throughput optimisation in production environments.

Practical benefits for workshop productivity

The insert’s 16 mm size and standardised form make it easy to integrate with common turning toolholders and indexable systems. The coated carbide construction balances wear resistance with reliable edge stability, translating to predictable tool-change intervals and simplified inventory management. Operators will find that cycle-to-cycle consistency improves when tools are specified for the material class—here specifically for rostfreier Stahl and high-temperature alloys—so production planning and cost-per-part calculations become more accurate.

Application advice and limits

This insert excels on rostfreier Stahl and nickel-based alloys and is well suited to many high-temperature applications where heat and adhesion present challenges. For titanium and other materials with poor thermal conductivity, the WSM30S composition provides enhanced heat resistance; however, machining parameters must be adapted—feed rates, depths of cut and cutting speeds should be set according to toolholder rigidity and machine capability. Where uncertain, process trials under controlled conditions are recommended to determine optimal settings and to confirm expected tool life.
