CCMT120412-RM4 WSM30S — Rhombic 80° indexable insert for stainless steel and superalloys, Tiger‑tec Silver by Walter Tools

A robust CCMT120412-RM4 WSM30S indexable insert designed for turning and boring applications in tough, heat‑resistant materials where secure chip formation and edge stability are critical

• Tiger‑tec Silver coated carbide grade WSM30S
• RM4 chipbreaker for secure chip control
• Rhombic 80° form with 1.2 mm corner radius
• 7° clearance angle for stable cutting

High‑temperature performance and broad material range

The combination of the Tiger‑tec Silver technology and the WSM30S grade delivers a coating system optimised for heat resistance and stable cutting edge retention. This makes the insert particularly suitable for machining stainless steels and H‑series superalloys, materials that tend to generate heat and cause built‑up edge. The coating reduces thermal loading at the cutting zone, while the carbide base provides the hardness needed for repeatable performance. For operations that demand consistent component quality, the material pairing provides a clear productivity advantage.

Precision geometry and secure chip control for reliable production

The rhombic 80° geometry with a 1.2 mm corner radius and an axial clearance of 7° ensures robust engagement and edge strength in interrupted or roughing passes. The RM4 chipbreaker is engineered to shape and evacuate chips effectively, reducing rework risk and protecting the workpiece surface. For workshops aiming to reduce cycle time and scrap rates, these geometric choices translate into fewer tool changes and more predictable process windows, especially where variable feed and depth are required.

Durable life and consistent surface finish for demanding series

The insert thickness and overall design support secure clamping and even force distribution across the cutting edge, which helps maintain surface integrity over longer tool life. Combined with the coated grade, this leads to lower frequency of indexing and improved machine uptime. In practice, that means fewer interruptions in series production and a more cost‑effective process. Where surface finish tolerances are critical, the combination of geometry and coating helps maintain dimensional stability between tool changes.
