CNMM120412-HU3 WPP05G — Rhombic 80° indexable turning insert, Tiger·tec Gold for steel by Walter Tools

The CNMM120412-HU3 WPP05G is a rhombic 80° indexable turning insert engineered for precision steel machining, combining a coated carbide grade with a negative 0° rake for robust cutting performance

Tiger·tec Gold coated carbide grade WPP05G
Optimised for steel machining (ISO P)
Rhombic 80° shape with 1.2 mm nose radius
Negative 0° rake for robust chip control

Consistent productivity and lower machining costs for steel turning

The Tiger·tec Gold WPP05G grade delivers a balance of wear resistance and toughness that suits a wide range of steel applications (ISO P). The coated carbide construction reduces flank wear and extends the life of the cutting edge, which translates into fewer indexings and less tool changeover time. This results in measurable improvements to spindle uptime and cutting tool economy while maintaining stable component dimensions and repeatable results.

Predictable chip formation and surface quality from optimised geometry

The combination of the HU3 chipbreaker, a rhombic 80° form and a 1.2 mm nose radius produces reliable chip control and good surface finish on turning operations. The negative 0° free angle increases edge strength and favours controlled chip flow under interrupted or heavy cuts. For operations requiring dependable chip evacuation and consistent part appearance, this geometry reduces the risk of built-up edge and minimises rework.

Practical integration and application guidance for workshop use

Designed to the CNMM format, the insert thickness and form suit standard toolholders for indexable turning; the 04 thickness and the rhombic design support a range of depths of cut while maintaining secure clamping. As the grade is optimised for steel, it is suitable for unalloyed and alloyed steels that typically demand thermal and mechanical resilience from the insert. If further process data is required—such as recommended speeds, feeds or coolant practice—Metav Werkzeuge provides technical guidance to tailor parameters to the specific machine, material and productivity targets.

FAQ

What materials is this insert suitable for?
The CNMM120412-HU3 WPP05G from Walter Tools is optimised for steel (ISO P), covering a broad range of unalloyed and alloyed steels.

How does the Tiger·tec Gold coating benefit production?
The Tiger·tec Gold coating on the WPP05G grade improves wear resistance and edge robustness, which supports longer tool life and more stable machining cycles.

What advantage does the negative 0° geometry provide?
A negative 0° free angle increases edge strength for heavy or interrupted cuts, offering improved process reliability during demanding turning operations.

Is the HU3 chipbreaker suitable for finishing or roughing?
The HU3 chipbreaker is designed for controlled chip formation and can be used across medium cutting conditions; it supports consistent surface quality while maintaining stable chip flow.

Which toolholders are compatible with this insert format?
The CNMM designation indicates compatibility with standard CNMM indexable turning toolholders; confirm holder clamping and seat specifications before mounting the insert.
