High-performance grade for difficult-to-machine materials

The WSM20S grade, part of the Tiger·tec Silver series, is a coated carbide designed specifically for applications involving stainless steels and superalloys. Its composition promotes stable cutting edge behaviour and improved resistance to thermal loading, which reduces edge breakdown and supports longer tool life. In practice, this means fewer insert changes and more consistent part quality in components where material toughness and heat generation typically challenge standard grades.

Geometry and chip control that improve process consistency

The combination of the FW4 chipbreaker, rhombic 80° insert form and 7° clearance enhances chip control and contact conditions at the cutting zone. The 0.8 mm nose radius balances strength and surface finish, enabling reliable roughing with qualified finishing capability where form tolerance matters. Such geometry reduces vibration and promotes reproducible surface integrity, particularly on parts where repeatable dimensional accuracy is essential for downstream assembly.

Productivity benefits and reliable tool behaviour

Tolerance class M, compact size 06 and plate thickness 02 ensure repeatable mounting and stable clamping for automated toolholders. As an indexable insert, the component supports fast index changes and cost-effective use of insert corners, contributing to improved spindle uptime and lower per-part tooling cost. The grade’s focus on secure chip formation and edge retention delivers measurable productivity gains on series production of corrosion-resistant components and high-temperature alloy parts.

Application guidance and selection support

For practical selection, the insert performs best in turning operations on rostfreier Stahl and materials classified under ISO groups S and M, where heat resistance and edge stability are critical. When matching insert geometry and cutting data to specific machines or part geometries, Metav Werkzeuge’s technical advisers can provide tailored recommendations and cutting parameters to ensure optimal performance and process reliability.
