TCMT16T308-FM6 WSM20S — Turning insert for rostfreier Stahl and superalloys | Walter Tools

The TCMT16T308-FM6 WSM20S is a triangular, coated carbide turning insert developed for demanding turning applications on rostfreier Stahl and heat‑resistant superalloys.

• Tiger·tec Silver coating for high process security
• Grade WSM20S for rostfreier Stahl and superalloys
• Triangle 60° with 0.8 mm corner radius
• 7° relief angle for reliable chip control

Optimised for tough materials and thermal loads

The Tiger·tec Silver coating in conjunction with the WSM20S grade provides thermal stability and improved resistance to built‑up edge when machining rostfreier Stahl and nickel‑based alloys. This combination reduces flank wear and supports a stable cutting edge, which in practice means longer tool life and fewer insert changes per shift. The insert’s coated carbide substrate is engineered to dissipate heat more effectively than conventional uncoated grades, helping to maintain dimensional accuracy over extended runs and reducing unscheduled stoppages in production.

Consistent chip formation and surface quality

With the FM6 chipbreaker and a 0.8 mm corner radius on a triangle 60° platform, this insert is designed for controlled chip segmentation and predictable flow. The 7° relief angle contributes to low friction at the cutting zone and minimises the risk of edge build‑up, resulting in a superior surface finish and reduced rework. For operations where consistent cycle times matter, such as batch turning of shafts or components in rostfreier Stahl, the predictable chip behaviour helps maintain productivity and reduces machine downtime caused by poor chip evacuation.

Process reliability and economic machining

The TCMT format with T3 thickness and tolerance class M offers mechanical stability for moderate to heavy cuts while remaining compatible with standard toolholder systems. The grade’s focus on heat resistance and edge stability allows higher cutting parameters on difficult alloys, so the investment repays through fewer tool changes and improved throughput. In addition, the standardised triangular geometry simplifies inventory management and interchangeability across turning centres, supporting a lean toolroom strategy and consistent part quality across multiple machines.
