SNMG120408-RM5 WMP20G — Indexable turning insert, Tiger·tec Gold coating, Walter Tools

The SNMG120408-RM5 WMP20G is an indexable turning insert engineered for medium to robust machining of stainless steel, offering a secure cutting edge and consistent chip formation in demanding production environments.

• Tiger·tec Gold coating for improved edge life
• WMP20G grade optimised for stainless steels
• Square 90° form with 0.8 mm corner radius
• RM5 chipbreaker for predictable chip control

Consistent results in stainless steel production

The combination of the WMP20G carbide grade and Tiger·tec Gold coating is engineered to address the specific challenges of machining stainless steel. The coating increases heat resistance and reduces adhesion at the cutting edge, which supports stable chip formation and lowers the risk of built-up edge under moderate to heavy cutting conditions. For production planning this means fewer unplanned tool changes and improved process reliability, resulting in more predictable part quality and higher throughput.

Robust edge geometry and dependable chip control

With a square 90° plate form and a 0.8 mm corner radius, the insert provides a strong cutting edge suitable for turning operations where edge strength and tool life are priorities. The RM5 chipbreaker is designed for controlled chip shaping in medium-depth cuts; it promotes short, consistently formed chips that evacuate reliably, reducing the likelihood of surface damage or machine interruptions. The negative 0° rake increases edge stability, making the insert particularly resilient during interrupted cuts and heavier depths of cut.

Efficient integration and production benefits

As an indexable insert, the SNMG120408-RM5 WMP20G simplifies tool management: each plate provides multiple cutting edges, reducing tooling costs per component and minimising downtime for index changes. The plate designation (size 12, thickness 04) follows standard ISO conventions, helping with toolholder compatibility and process documentation. Specifying this insert for stainless steel applications supports a balance between economic efficiency and machining performance, especially when reproducible surface finish and extended edge life are required in serial production.

FAQ

What materials is this insert suitable for?
The SNMG120408-RM5 WMP20G insert is specified for machining stainless steel (ISO material group M) and is optimised for medium to robust cutting conditions where heat and adhesion tendencies require a coated carbide grade.

What advantages does the Tiger·tec Gold coating deliver?
Tiger·tec Gold on the WMP20G grade enhances heat resistance and reduces edge adhesion, which improves cutting-edge life and process stability when using the SNMG120408-RM5 WMP20G insert in demanding stainless steel operations.

How does the RM5 chipbreaker perform in practice?
The RM5 chipbreaker is engineered for predictable chip formation in medium-depth turning; it produces compact chips that evacuate reliably, supporting surface integrity and reducing the risk of chip-related interruptions with the Walter Tools insert.

Which geometric details should be noted when selecting a toolholder?
The SNMG120408-RM5 WMP20G is a square 90° insert with a 0.8 mm corner radius and thickness designation 04; confirm toolholder compatibility for SNMG 12‑series plates and negative 0° rake configurations when setting up the turning tool.
