VCMT160404-RM4 WMP20S turning insert — Tiger·tec Silver grade for stainless steel | Walter Tools

The VCMT160404-RM20S WMP20S is a rhombic 35° indexable turning insert designed for reliable machining of stainless steels in medium to robust cutting conditions.

• Tiger·tec Silver coated carbide grade WMP20S
• Optimised RM4 chipformer for stable chip control
• Rhombic 35° geometry with 7° relief angle
• Suitable for stainless steel turning (ISO M)

Stable chip formation and reliable edge life

The combination of the Tiger·tec Silver coating and the WMP20S carbide grade promotes stable chip formation when machining stainless steels, a material group prone to built-up edge and high heat generation. The RM4 chipformer is optimised to break and evacuate chips effectively, reducing the risk of entanglement and surface damage. This technical set-up translates into longer in-process edge life and fewer tool changes, supporting a more continuous and predictable production flow for turning operations.

Precision geometry for improved surface finish

The insert’s rhombic 35° geometry, combined with a 0.4 mm nose radius and a 7° relief angle, is configured to provide a balance between access to tight contours and an even cutting load. These geometry parameters support a consistent surface finish and repeatable dimensional control during finishing passes. The indexable format allows for rapid corner changes, maintaining process reliability without complex regrinding, which is beneficial in job shops and production environments that demand reproducible results.

Enhanced productivity and process security

Engineered for medium to robust applications, the WMP20S grade in the Tiger·tec Silver series is tailored to the challenges of machining stainless steels under ISO M conditions. The coated carbide substrate offers improved thermal resistance and wear behaviour, which supports higher productivity through longer intervals between insert changes. For manufacturing environments focused on process security and uptime, the insert’s balanced properties help reduce scrap rates and contribute to predictable tool costs over production cycles.
