CNMG120412-MW5 WPP05G turning insert – Tiger·tec Gold, rhombic 80° by Walter Tools

The CNMG120412-MW5 WPP05G is a rhombic 80° turning insert designed for productive steel machining with a Tiger·tec Gold coated, coated-carbide grade.

• Tiger·tec Gold coating for edge stability
• MW5 chipformer for controlled chip formation
• Rhombic 80° geometry for versatile turning
• r=1.2 mm corner radius for robust finishing

Higher process reliability through a coated carbide grade

The combination of the Tiger·tec Gold coating and the WPP05G grade yields a balance between wear resistance and toughness specifically tailored for steels (ISO P). The coating reduces flank and crater wear under typical turning conditions, extending tool life and lowering process costs. Because the grade is optimised for steel, it manages the heat and chip formation typical of alloyed and unalloyed steels, supporting consistent component quality and fewer tool changes during batch runs.

Geometry and chip control that improve productivity

The rhombic 80° shape with a 0° (negative) free angle and a r=1.2 mm corner radius provides a stable cutting edge for interrupted cuts and medium finishing operations. The MW5 chipformer is engineered to break and evacuate chips reliably when machining ISO P materials, reducing rework and toolholder issues. A negative rake preserves cutting-edge strength, which is especially valuable when facing variable workpiece conditions or hard spots in steel.

Versatility across wear-resistant to tougher steel grades

This insert’s carbide substrate and coating technology make it suitable across a range of steel conditions, from more wear-prone to tougher grades as classified within the WPP05G application spectrum. The insert supports steady metal removal rates and produces repeatable surface quality, meaning fewer process adjustments are needed when switching between similar steel families. This stability contributes to predictable cycle times and helps maintain production schedules.

Practical handling, compatibility and economic benefits

The CNMG form matches common toolholder pockets for turning applications, allowing straightforward tool setup and replacement. With the WPP05G composition and Tiger·tec Gold surface, users can expect improved flank wear resistance and reliable edge retention, which together reduce tooling consumption over time. The robust corner radius and coated substrate help achieve a balance between acceptable surface finish and longer operational intervals, improving overall machining economy.

FAQ

Which materials are suitable for this insert?
The CNMG120412-MW5 WPP05G insert is designed for steel machining and aligns with the ISO P material group.

What does the WPP05G grade indicate?
WPP05G denotes Walter Tools’ coated-carbide grade within the Tiger·tec Gold technology, balancing wear resistance and toughness for steel.

How does the MW5 chipformer benefit machining?
The MW5 chipformer on this turning insert promotes reliable chip breaking and evacuation when turning steels, reducing the risk of chip entanglement and improving process stability.

Why choose a negative 0° free angle for turning?
A 0° (negative) free angle increases edge strength and resistance to shock, making the insert suitable for interrupted cuts or unstable workpiece conditions.

What is the advantage of the r=1.2 mm corner radius?
The 1.2 mm corner radius provides a compromise between robustness and surface finish, allowing modest finishing while preserving edge life.
