CNMG120416-RM5 WMP30G indexable turning insert — Walter Tools, optimised for stainless steel machining

CNMG120416-RM5 WMP30G is an indexable turning insert designed for secure cutting and stable chip formation in stainless‑steel applications, suited to medium to heavy conditions

• Tiger‑tec Gold coating for improved tool life
• Optimised RM5 chipbreaker for stainless steel
• Rhombic 80° geometry for versatile turning
• 1.6 mm corner radius for robust edge strength

Consistent performance in stainless‑steel turning

The insert grade WMP30G, used in the Tiger‑tec Gold series, is engineered for rostfreier Stahl where material toughness and heat generation demand stable cutting behaviour. The combination of a tailored coating and substrate supports controlled friction and reduced built‑up edge, which in practice leads to longer uninterrupted cutting intervals. The integrated RM5 chipbreaker promotes reliable chip segmentation under varying feeds, improving process stability and reducing tool‑related interruptions in productive setups.

Reliable edge stability and repeatable results

The rhombic 80° geometry and a 1.6 mm corner radius provide a balance between edge strength and form versatility, making the insert suitable for both finishing and semi‑roughing passes where repeatability matters. The 0° (negative) rake characteristic increases edge robustness, helping maintain an even cutting edge under higher mechanical loads. This geometry supports consistent dimensional results and a predictable tool life profile, which is particularly valuable in series production and contract machining.

Practical benefits for production efficiency

Using an indexable format reduces tool change time and simplifies inventory management compared with brazed tools. The CNMG outline offers access to common toolholder families, while the plate thickness code and form support adequate rigidity for heavier cuts. Improved chip control from the RM5 design lowers the need for manual chip clearing and minimises risk to finished surfaces, contributing to smoother workflow and reduced secondary operations in the machining cell.

Guidance on selection and technical explanation

The designation indicates the insert form and intended function: a rhombic insert with a medium to robust corner radius and dedicated chipbreaker for stainless‑steel machining. The Tiger‑tec Gold coating is a multilayer PVD/CVD technology tailored to reduce adhesion and extend wear resistance on tough alloys. For users assessing tooling options, the CNMG120416‑RM5 WMP30G insert from Walter Tools is a practical choice where stable chip formation and extended edge life are priorities; Metav Werkzeuge can advise on matching holders and cutting parameters.

FAQ

What materials is this insert suitable for?
The CNMG120416‑RM5 WMP30G insert is specified for rostfreier Stahl (stainless steel) and is optimised for the typical cutting behaviour of that group.

What advantage does the Tiger‑tec Gold coating provide?
Tiger‑tec Gold on the WMP30G grade enhances wear resistance and reduces adhesion, supporting longer cutting intervals and more consistent tool life when machining stainless steels.

How does the RM5 chipbreaker affect machining?
The RM5 chipbreaker promotes controlled chip segmentation for improved evacuation and surface integrity; the design helps maintain stable cutting even under varying feeds.

Is the rhombic 80° geometry versatile for different turning tasks?
Yes, the rhombic 80° form offers access to various turning operations and toolholder types while balancing approach angle and strength for both finishing and semi‑roughing.

How is the corner radius relevant for application?
A 1.6 mm corner radius provides increased edge strength, reducing the likelihood of chipping under heavier cuts and contributing to repeatable dimensional results.
