WCMT06T304-MM4 WSM20S — indexable insert for drilling and turning by Walter Tools (Trigon 80°, Tiger·tec Silver)

The WCMT06T304-MM4 WSM20S is an indexable insert tailored for demanding machining tasks, offering secure chip formation and thermal resistance for rostfreier Stahl and heat-resistant superalloys.

• Tiger·tec Silver coating for heat resistance
• Trigon 80° shape for secure chip control
• 0.4 mm nose radius for fine surface finishes
• Designed for rostfreier Stahl and superalloys

Consistent surface quality through precise geometry and edge control

The Trigon 80° design combined with a 0.4 mm nose radius ensures a predictable engagement angle and controlled cutting action, which directly improves surface finish and repeatability. For machining operations that require fine tolerances, the insert’s geometry reduces vibration and supports a stable cutting edge, translating into fewer reworks and more parts meeting specification on the first pass. This geometry is especially useful in small-diameter boring and finishing turning where tool stability determines the final contour quality.

High-temperature resilience and reliable chip formation for difficult materials

Equipped with the Tiger·tec Silver coating and the WSM20S grade, the insert sustains cutting temperatures and chemical wear typical of rostfreier Stahl and heat-resistant superalloys. The coating technology emphasises thermal shielding and wear resistance, allowing higher cutting parameters with reduced risk of built-up edge. In practice, this leads to longer tool life and more consistent component quality when machining materials that tend to work-harden or generate adhesive wear on the cutting edge.

Productivity gains from chip management and robust construction

The MM4 chipbreaker, combined with the Trigon form and T3 thickness, promotes dependable chip control across varied cutting conditions, lowering downtime caused by chip entanglement. The plate’s tolerance class M aligns with stable insert seating and repeatable indexability in turret or toolholder systems, supporting efficient changeovers and predictable process windows. Overall, the combination of chip control, coating and mechanical stability contributes to improved cycle times and a lower cost-per-part in series production.
