CNMG120408-RM5 WPP20G indexable turning insert — Tiger·tec Gold, Walter Tools

A CNMG120408-RM5 WPP20G indexable turning insert designed for robust steel machining, featuring the Tiger·tec Gold coating and an RM5 chipbreaker for controlled chip formation

• Tiger·tec Gold coating for high wear resistance
• RM5 chipbreaker for reliable chip control
• Rhombic 80° form, 0.8 mm corner radius
• Optimised for steel (ISO P) machining

Durable coating that extends productive tool life

The Tiger·tec Gold coating and the WPP20G cemented‑carbide grade deliver a combination of wear resistance and toughness that is tailored to the thermal and mechanical conditions encountered when machining steel. The multilayer coating reduces flank wear and improves edge stability under repeated cutting cycles, which leads to longer tool life and fewer index changes. By choosing a coated carbide insert with an optimised microstructure, process planners gain measurable benefits in tooling costs and machine uptime without sacrificing component quality.

Geometry engineered for stable cutting and surface quality

The rhombic 80° form and 0.8 mm corner radius create a robust cutting edge that resists chipping while supporting a consistent cutting force vector, particularly during finishing and medium‑duty turning operations. The 0° negative relief ensures a secure seat in the toolholder and reduces vibration in heavy cuts, resulting in improved surface finish and dimensional repeatability. Together, the geometry and the RM5 chipbreaker control chip flow and minimise rework risks, which supports a smoother production flow and higher first‑pass yield.

Optimised for steel applications with clear process advantages

Specified for ISO P materials, this insert is engineered to handle a wide range of steels, from unalloyed to alloyed grades, where heat generation and chip formation patterns are a dominant factor. The RM5 chipbreaker facilitates reliable chip segmentation and evacuation across common turning parameters, reducing manual intervention and cycle time. For manufacturers seeking predictable productivity, the combination of grade, chipbreaker and geometry provides a cost‑effective solution that balances cutting performance and tool life.

FAQ

What materials is this insert intended for?
The CNMG120408-RM5 WPP20G is optimised for ISO P materials, meaning it is intended primarily for machining various steels.

How does the RM5 chipbreaker affect chip formation?
The RM5 chipbreaker on this Walter Tools insert improves chip segmentation and evacuation during turning, reducing entanglement and supporting continuous production.

Is the corner radius suitable for finishing operations?
A 0.8 mm corner radius provides a balance between edge strength and surface finish, making the insert suitable for many finishing to medium‑duty turning tasks.

Can this insert be used in negative‑geometry toolholders?
Yes, the 0° negative relief and rhombic 80° form are compatible with standard negative‑geometry indexable toolholders designed for CNMG inserts.

How does the Tiger·tec Gold coating benefit productivity?
The Tiger·tec Gold coating enhances wear resistance and edge stability, which translates to longer tool life and fewer interruptions for insert changes during steel turning.
