TCMT16T312‑RM4 WSM20S triangular indexable insert — 1.2 mm radius, Tiger‑tec Silver, Walter Tools

A TCMT16T312‑RM4 WSM20S indexable turning insert designed for machining stainless steels and heat‑resistant superalloys in both roughing and finishing operations

• Tiger‑tec Silver coated carbide
• Optimised RM4 chipbreaker
• Triangle 60° geometry
• Corner radius 1.2 mm

Reliable performance for demanding materials

The coated carbide grade WSM20S from the Tiger‑tec Silver family provides a balance of wear resistance and edge stability that benefits machining of stainless steels and heat‑resistant alloys. The coating and substrate combination promotes predictable wear patterns and reduces the risk of built‑up edge, which in turn helps to extend tool life and maintain component quality. For production environments where thermal load and material toughness challenge the cutting edge, this insert offers consistent results through enhanced heat resistance and improved chip evacuation.

Consistent chip control and surface quality

The RM4 chipbreaker geometry combined with the triangle 60° form ensures controlled chip formation and reliable evacuation under varying cutting conditions. A corner radius of 1.2 mm contributes to a robust cutting edge that reduces vibration and supports repeatable dimensional accuracy. The insert’s clearance angle of 7° is optimised for secure cutting action and reduced rubbing on the flank, which helps achieve a superior surface finish while maintaining feed rates appropriate for the task. In short, these design choices reduce rework and increase throughput in series production.

Process security, tool life and integration into tooling systems

Triangular inserts such as this one allow three usable cutting edges per index, supporting economic operation and predictable tool changes. The TCMT16T312‑RM4 WSM20S specification combines a practical insert size (16 mm) and standard thickness (T3) for easy integration into common turning holders. The coated grade is particularly resilient in heat‑generating applications, which translates into fewer tool interventions and higher machine uptime. For workshops seeking a robust, versatile consumable, the combination of geometry, coating and chip control makes this insert a sound choice for stable, efficient machining.
