CCMT120404-RM4 WMP20S — Turning indexable insert, Tiger·tec Silver, Walter Tools

The CCMT120404-RM4 WMP20S is a rhombic 80° indexable insert designed for turning operations, optimised for secure chip control and consistent performance when machining stainless steels.

• High-performance WMP20S grade for stainless steels
• Tiger·tec Silver coating for extended tool life
• RM4 chipbreaker for stable chip formation
• Rhombic 80° geometry for versatile turning

Reliable grade and coating for tough materials

The insert combines the WMP20S carbide grade with the Tiger·tec Silver coating to address the specific challenges of machining stainless steels. This pairing improves thermal resistance and wear behaviour, reducing edge build-up under demanding conditions. As a result, operators benefit from consistent tool life and fewer interruptions for insert changes, which supports a more efficient production flow and predictable cycle times.

Predictable chip control and improved surface quality

Equipped with the RM4 chipbreaker and a rhombic 80° form, the insert promotes stable chip formation and safe evacuation of swarf in interrupted or continuous cuts. The controlled chips reduce the risk of workpiece surface damage and allow for finer feed and speed settings, delivering a better finish without sacrificing productivity. This leads to fewer rework cycles and a more reliable dimensional outcome in serial turning operations.

Geometry and dimensions that support productivity

The geometry, including the corner radius 0.4 mm and 7° clearance, balances strength at the cutting edge with the ability to achieve accurate contours. The nominal inscribed circle of 12 mm and a plate thickness derived from the CCMT coding ensure compatibility with common toolholders and straightforward replacement. Together, these design choices provide a robust compromise between edge strength and finishing capability, helping maintain process stability over longer runs.
