CNMG190612-RM5 WMP20G turning insert for rostfreier Stahl by Walter Tools — Rhombic 80°, 1.2 mm corner radius

The CNMG190612-RM5 WMP20G is a coated carbide turning insert designed for machining rostfreier Stahl under medium to robust cutting conditions, combining a Tiger·tec Gold coating with an RM5 chipbreaker to support secure chip formation and stable cutting edges.

• Tiger·tec Gold coating for stable edge life
• RM5 chipbreaker optimised for rostfreier Stahl
• Rhombic 80° form with 1.2 mm corner radius
• Negative 0° rake for robust cutting performance

Reliable cutting performance for rostfreier Stahl with coated carbide technology

The coated carbide composition of the insert, identified by the WMP20G grade and protected with Tiger·tec Gold, is engineered to reduce the typical risks of machining rostfreier Stahl such as work hardening and built-up edge. The combination of a wear-resistant coating and a dedicated chipbreaker promotes stable chip formation, which in turn lowers the frequency of interruptions for chip clearing and contributes to longer uninterrupted production runs. By favouring steady cutting behaviour over aggressive metal removal alone, the insert improves process predictability and reduces scrap rates while maintaining consistent part tolerances.

Geometry designed for consistent surface quality and tool life

The Rhombic 80° geometry and the 1.2 mm corner radius provide a balance between edge strength and finishing capability: the obtuse cutting angle distributes cutting forces across a larger edge, reducing the risk of edge chipping during intermittent cuts, while the rounded corner helps achieve a predictable surface finish. The negative 0° rake further reinforces the cutting edge for robust engagement in tougher conditions, making the insert particularly suitable where fixture stability is variable or where heavier depths of cut are required. These geometric choices translate into fewer tool changes and more repeatable cycles on the shop floor.

Productivity and process security through optimised chip control

Equipped with the RM5 chipbreaker, this insert supports manageable chip shapes for rostfreier Stahl, decreasing the chance of problematic chips that can damage the workpiece or machine. Improved chip control enhances overall process security and contributes directly to higher productivity by reducing downtime for cleaning and rework. As a Walter Tools product made for industrial use, the insert aligns with expectations for consistent performance, allowing planners to quantify tool life more reliably and to plan maintenance and tool replenishment with greater confidence.

FAQ

What materials is this insert intended for?
This turning insert is designed primarily for machining rostfreier Stahl; the WMP20G grade and Tiger·tec Gold coating support secure chip formation when working with these materials.

How does the RM5 chipbreaker help in practice?
The RM5 chipbreaker on the CNMG190612-RM5 WMP20G insert shapes chips to reduce entanglement and improve evacuation, which supports continuous cutting and lowers the risk of workpiece damage.

What advantages does the Rhombic 80° form provide?
A Rhombic 80° form offers a robust cutting edge and flexible approach angles, enabling repeatable surface integrity and enhanced edge strength for intermittent or heavier cuts.

Is the negative 0° rake suitable for unstable setups?
Yes, the negative 0° rake increases edge robustness, making this insert suitable for setups where rigidity varies or where heavier depths of cut are required.

Can the CNMG190612-RM5 WMP20G be used for finishing as well as roughing?
The geometry and 1.2 mm corner radius balance strength and finish capability, so the insert can be used for both roughing and semi-finishing operations depending on cutting data and machine stability.
