WCGT040202-FM2 WSM21 – Trigon 80° indexable insert for boring and turning, Walter Tools

A WCGT040202-FM2 WSM21 indexable insert engineered for secure chip control and durable cutting when machining rostfreier Stahl and high‑temperature superalloys in boring and turning operations

• Coated carbide grade WSM21
• FM2 chipbreaker for stable chip control
• Trigon 80° geometry for positive cutting
• Suited to rostfreier Stahl and superalloys

Higher throughput through material‑specific coating and edge stability

The combination of a coated carbide grade designed as WSM21 and a robust insert form produces measurable productivity gains when tackling difficult‑to‑cut materials. The coating supports thermal resistance and helps maintain a sharp cutting edge under the high temperatures typical of machining rostfreier Stahl and heat‑resistant superalloys. Because the grade is optimised for such alloys, tool life is extended and changeover frequency is reduced, which lowers process interruptions and contributes directly to improved output efficiency.

Consistent surface quality with controlled chip formation

Chip control is central to predictable turning and boring cycles. The FM2 chipbreaker, paired with the Trigon 80° form and a 0.2 mm corner radius, promotes short, manageable chips and stable cutting forces. This geometry reduces built‑up edge formation while delivering a consistent cutting action that supports repeatable surface finish. For operations where tool access and clearance are constrained, the positive rake and compact corner aid in achieving dimensional accuracy without compromising edge life.

Practical application and mounting considerations for dependable results

The insert’s relief of 7° and standard size/thickness codes allow straightforward integration into common toolholders designed for Trigon inserts; selection of the correct holder and clamping torque ensures the intended performance. The plate is available in size code 04 with thickness code 02 and tolerance class G, providing predictable mechanical fit‑up in indexable tool systems. For adaptations to specific cycles or atypical alloys, Metav Werkzeuge offers application guidance and cutting data to match the insert’s properties with feed, speed and depth settings appropriate for the workpiece and machine capability.
