CNMG120408-RP5 WPP05G – Indexable turning insert with Tiger·tec Gold coating for steel | Walter Tools

A CNMG120408-RP5 WPP05G indexable turning insert, designed as a rhombic 80° geometry with a negative 0° rake, optimised for general steel turning applications in ISO P material groups

• Tiger·tec Gold coating for long tool life
• Optimised for steel (ISO P) machining
• Negative 0° rake, rhombic 80° geometry
• 0.8 mm corner radius with RP5 chipbreaker

Higher throughput through a wear‑resistant grade

The combination of the WPP05G grade and Tiger·tec Gold coating delivers a balanced mix of hardness and toughness that supports high metal removal rates in steel machining. As a coated carbide grade formulated for ISO P, the insert maintains a stable cutting edge under the thermal and mechanical loads typical of turning steel, which results in longer tool life and fewer interruptions to the production flow. The RP5 chipbreaker contributes to predictable wear progression, enabling planners to estimate tool life with greater confidence and optimise tool-change intervals for improved overall equipment effectiveness.

Cleaner chips and improved surface integrity

A negative 0° rake angle paired with an RP5 chipbreaker and a 0.8 mm corner radius promotes effective chip formation and evacuation during continuous turning operations. This geometry reduces the tendency for serrated or uncontrolled chips when machining steels and helps to produce a consistent surface finish, lowering the need for rework. The rhombic 80° shape provides flexibility for both external and facing cuts while the designated corner radius supports modest finishing passes without compromising cutting edge strength, offering a clear balance between durability and surface quality.

Easy adoption and reproducible results on standard holders

The insert’s standard CNMG designation and tolerance class M ensure compatibility with established toolholder systems and predictable seating accuracy. With a size designation of 12 and a thickness code of 04, the component integrates into common turning tool setups, allowing for straightforward replacement and minimal setup adjustments. For process planning, the insert’s focus on steel (ISO P) simplifies material selection and cutting-condition recommendations. For application matching and process parameters, Metav Werkzeuge provides technical support and advice to align the insert characteristics with specific machine and workpiece requirements.

FAQ

Which materials is this insert intended for? The CNMG120408-RP5 WPP05G insert is specified for machining steel (ISO P); the WPP05G grade and Tiger·tec Gold coating are tuned to the heat and chip formation typical of steel turning.

What advantages does the RP5 chipbreaker provide? The RP5 chipbreaker on this turning insert improves chip control and evacuation in continuous turning, supporting consistent surface finish and reducing the risk of chip entanglement.

How does the negative 0° rake affect machining performance? A negative 0° rake increases edge strength and is beneficial for interrupted cuts and tougher steels; it reduces cutting-edge deflection and supports stable flank wear behaviour.

Is the insert compatible with standard CNMG toolholders? Yes, the CNMG120408-RP5 WPP05G follows the CNMG indexable insert form and fits standard holders designed for CNMG geometry, enabling straightforward replacement and repeatable seating.
