CCMT120408-RM4 WSM20S indexable turning insert — Walter Tools, Tiger·tec Silver, RM4

The CCMT120408-RM4 WSM20S is an indexable turning insert designed for demanding work on stainless steels and heat‑resistant alloys, featuring a Tiger·tec Silver coating and a chipbreaker tailored for secure chip formation

• Tiger·tec Silver coating
• Optimised for stainless steels (M)
• Stable cutting edge for superalloys (S)
• Rhombic 80° format, 0.8 mm corner radius

High‑temperature coating that stabilises cutting performance

The advanced Tiger·tec Silver coating offers a balanced combination of wear resistance and thermal stability that supports consistent cutting in tough materials. For components made from stainless steel and heat‑resistant alloys the coating reduces built‑up edge and extends effective cutting life, which translates into fewer insert changes and less downtime. This performance advantage is particularly relevant where heat generation and poor thermal conductivity compromise tool life; the combination of coating and substrate ensures a predictable, repeatable machining result.

Geometry and chip control for safer heavy machining

The insert’s rhombic 80° form and 0.8 mm corner radius deliver a mix of strength at the cutting edge and accessibility for various turning operations. The RM4 chipbreaker is engineered to produce short, controllable chips under demanding conditions, improving surface finish and reducing the risk of chip entanglement. A small relief angle of 7° supports low cutting forces in finish passes while maintaining edge support for roughing, so stable, repeatable parts can be achieved across batch runs.

Application focus and process advantages in production

Engineered as a coated carbide grade, WSM20S is aimed at series production and repair tasks where material variability and thermal challenges exist. The insert’s balanced properties favour applications that require constant dimensional accuracy and reduced rework, such as medical components, aerospace airframes and precision food‑processing parts in rostfrei materials. Integrated geometry and coating choices contribute to higher process security and consistent surface quality, making the solution a cost‑effective choice for producers seeking dependable throughput.
