TCMT090208-RM4 WSM20S turning indexable insert (Tiger·tec Silver) by Walter Tools — for rostfreier Stahl and heat-resistant alloys

The TCMT090208-RM4 WSM20S turning indexable insert is designed for demanding turning and boring tasks in rostfreier Stahl and temperature-resistant superalloys, offering stable edges and predictable tool life.

• Tiger·tec Silver coating for wear resistance
• WSM20S grade optimised for rostfreier Stahl
• RM4 chipbreaker for controlled chip formation
• Triangle 60° insert with 0.8 mm corner radius

High wear resistance where heat and toughness meet

The Tiger·tec Silver coating combined with the WSM20S grade delivers wear resistance and a stable cutting edge when machining tough materials. This composition is specifically engineered for applications involving rostfreier Stahl and heat-resistant superalloys, where thermal loads and material toughness challenge conventional grades. The coating technology supports secure chip formation and reduced adhesive wear, which contributes to longer effective life of the cutting edge and fewer unscheduled tool changes. As a result, machining cycles remain consistent and surface integrity is improved without complex parameter adjustments.

Predictable chip control and surface quality through geometry

The triangular 60° insert geometry with a 0.8 mm corner radius and the RM4 chipbreaker provides reliable chip segmentation and evacuation in both continuous and interrupted cuts. The 7° clearance angle minimises rubbing while maintaining edge strength, and the specific chipbreaker geometry supports short, controllable chips that reduce the risk of workpiece damage and tool breakouts. For operations where build-up edge or heat concentration can compromise results, this geometry enhances surface finish and dimensional stability while keeping the process robust and reproducible.

Easy integration into production and efficient process economics

With tolerance class M and the compact designation TCMT090208-RM4 WSM20S, the insert integrates seamlessly into standard toolholders for turning and boring operations. The combination of predictable wear characteristics and an industry-proven grade means fewer spare items in stock and simpler tool management. Process planners benefit from consistent cycle times and a reduction in rework rates, while workshop supervisors gain enhanced reproducibility across batches. The specification supports both roughing and semi-finishing strategies in rostfreier Stahl and high-temperature alloys, offering a balance between productivity and surface quality.
