CCMT120412-E47 WSM20S drilling/boring indexable insert, Tiger‑tec Silver, Walter Tools — 1.2 mm radius, 7° relief The CCMT120412-E47 WSM20S is a rhombic 80° indexable insert engineered for challenging machining of stainless steels and heat‑resistant superalloys in turning and boring applications. Indexable insert CCMT120412-E47, rhombic 80° Tiger‑tec Silver coated WSM20S grade 7° relief for stable cutting Suitable for stainless steels and superalloys Reliable cutting in difficult alloys for fewer interruptions The coated cutting geometry delivers stable chip formation and repeatable results when machining materials known for work hardening and poor thermal conductivity. The WSM20S grade, part of the Tiger‑tec Silver series, is developed to resist thermal and mechanical wear, which translates into longer uninterrupted tool life and fewer tool changes. By combining a wear‑resistant coating with a robust substrate, this insert maintains cutting-edge integrity under elevated cutting temperatures typical of machining stainless steels and superalloys, so cycle times and tool consumption are reduced. Improved surface finish and predictable tool behaviour A defined corner radius 1.2 mm and the rhombic 80° shape control cutting forces and contact conditions, helping to achieve a consistent surface quality on difficult‑to‑cut workpieces. The moderate clearance provided by the 7° relief reduces the tendency for edge build‑up while supporting secure seating in the toolholder. As a result, the component finish benefits from reduced vibration and more stable cutting, which is particularly important for finishing passes and tight tolerance work in demanding production environments. Designed chip control and machining stability for productivity The E47 chipbreaker geometry is focused on fragmenting and evacuating chips efficiently under variable feeds. This contributes to safer machining, reduced rework and less downtime caused by chip entanglement. The insert’s design supports both roughing and finishing sequences depending on the chosen cutting data, providing flexibility in process planning and supporting higher overall productivity in series production or specialised workpieces. Practical selection and application guidance for process security This insert is best applied in operations where materials fall under ISO groups M and S — in other words, stainless steels and heat‑resistant superalloys or titanium alloys. Selection of the WSM20S grade is advisable when thermal stability and edge retention are priorities. Combine the insert with a suitable toolholder matched to the rhombic 80° geometry and apply cutting data that respects the substrate’s properties: moderate feed to manage heat and a stable clamping system to exploit the insert’s benefits for consistent part quality.
