WCMT080408-RM4 WSM20S Trigon 80° indexable insert by Walter Tools — Tiger·tec Silver for stainless steels and superalloys

The WCMT080408-RM4 WSM20S is a trigon-form indexable insert engineered for demanding turning and boring operations, optimised for stainless steels and heat-resistant superalloys where stable cutting edges and thermal resistance are essential.

• Tiger·tec Silver coating
• WSM20S grade for stainless steels and superalloys
• Trigon 80° insert form
• 7° relief angle, 0.8 mm corner radius

Stable cutting performance for demanding materials

The combination of the WSM20S grade and the Tiger·tec Silver coating provides a balance of thermal resistance and wear protection that is particularly suited to the challenges of machining stainless steels and superalloys. The coated carbide substrate reduces adhesion and built-up edge formation, which in turn maintains surface finish and dimensional consistency. For production environments where repeatability and low scrap rates matter, this insert grade reduces the need for frequent tool changes, supporting uninterrupted machining cycles and predictable component quality.

Geometry that enhances chip control and edge life

A Trigon 80° form gives this insert a robust cutting edge capable of handling entry forces during turning and boring, while the RM4 chipbreaker promotes reliable chip formation across a range of cutting depths. The 7° relief angle reduces contact on the flank face to limit rubbing, and the 0.8 mm corner radius provides strength at the cutting edge, helping to resist chipping under interrupted cuts. These geometric features translate into fewer unexpected tool failures and steadier cycle times, which benefits both single-shift workshops and high-volume production lines.

Practical advantages on the shop floor

This insert is coded and sized for straightforward integration into standard toolholders and toolboards, offering a familiar interface for machinists and process engineers. The grade’s focus on heat resistance and edge stability supports operations in sectors such as aerospace, power generation and medical manufacturing, where materials are often difficult to cut and tolerance demands are tight. With predictable wear behaviour and consistent chip control, the insert supports efficient post-process handling and reduces rework — a direct contribution to overall process economy and product reliability.
