RCMT0803M0-RM4 WSM20S indexable turning insert — Tiger·tec Silver, round form, 7° free angle — Walter Tools

The RCMT0803M0-RM4 WSM20S is a round indexable turning insert engineered for precision turning of rostfreier Stahl and heat‑resistant superalloys, offering a balance of edge stability and predictable chip formation.

• Tiger·tec Silver coating for heat resistance
• Optimised for rostfreier Stahl and superalloys
• RM4 chipbreaker for consistent chip control
• Round 08 form with 7° free angle

Consistent cutting performance in tough materials

The combination of the Tiger·tec Silver coating and the WSM20S grade provides a coated carbide solution tailored for high thermal and mechanical loads. This makes the insert particularly suited to machining rostfreier Stahl and materials classified under ISO group S, where heat resistance and preserved edge integrity are decisive. The resulting benefit is a more predictable process window and reduced risk of built‑up edge, which supports longer cutting intervals and more reliable batch production.

Stable chip control and secure edge behaviour

Equipped with the RM4 chipbreaker, the insert delivers controlled chip segmentation that aids evacuating swarf even in interrupted or difficult turning operations. Controlled chip form reduces tool and machine downtime associated with entangling chips and supports consistent surface quality. The insert geometry and chipbreaker are designed to produce short, manageable chips for both continuous and mildly interrupted cuts, improving operator safety and post‑process handling.

Geometry that supports versatile turning strategies

The round plate shape (form R) with a 7° free angle offers high strength at the cutting edge and permits variable lead‑in angles without compromising edge stability. The compact size (08) and plate thickness (03) facilitate use in a broad range of toolholder setups where rigidity is required. The tolerance class M and execution T denote manufacturing precision and clamping compatibility, contributing to reproducible positioning and repeatable performance in production environments.

Where this insert brings the greatest advantage

This grade is specifically developed for machining rostfreier Stahl and demanding superalloys where thermal resilience and wear resistance are required. Typical applications include finishing or semi‑finishing operations on components subject to high temperatures or poor thermal conductivity. The overall result is increased process security and consistent workpiece surface quality when the working conditions match the material groups M and S as defined under ISO 513.
