CNMM120408-HU3 CNMM120408-HU3 WPP30G Turning insert for steel (P) — Tiger·tec Gold by Walter Tools

The CNMM120408-HU3 WPP30G is a rhombic 80° turning insert with Tiger·tec Gold coating, designed for productive steel machining and reliable chip control.

• Tiger·tec Gold coated carbide grade WPP30G
• HU3 chipbreaker for dependable chip control
• Rhombic 80° shape with 0.8 mm corner radius
• 0° negative rake for stable, heavy cuts

Optimised coating and substrate for efficient steel machining

The combination of the Tiger·tec Gold coating and a coated carbide substrate provides a balanced performance specifically for ISO P applications — that is, machining unalloyed and alloyed steel. The coating reduces friction and thermal load at the cutting zone, which improves tool life and enables higher cutting parameters without sacrificing surface quality. In production terms, this means fewer tool changes, longer uninterrupted runtimes and more consistent component quality. The insert grade is tuned to the thermal and chip-formation behaviour typical for steel, offering a reproducible and cost‑efficient cutting process.

Geometry and chip management that increase productivity

The insert’s HU3 chipbreaker paired with a rhombic 80° geometry and a 0.8 mm corner radius delivers consistent chip formation and evacuation. The 0° negative rake contributes to a robust cutting edge that resists chipping under interrupted cuts and heavy feeds, supporting stable cycle times. These geometric features directly translate into improved surface finish and dimensional stability on turned parts, especially in medium to heavy‑duty operations where chip control and edge strength are decisive for uptime.

Practical application notes and selection guidance

This turning insert is suitable for a wide range of steel turning tasks within the ISO P group; the grade WPP30G provides a balance between wear resistance and toughness, making it a versatile choice in mixed production environments. The tolerance class M indicates standard dimensional accuracy for general turning operations. When selecting an insert geometry or corner radius for a specific job, consider the required surface finish and the feed rates: the 0.8 mm corner radius is effective for general finishing to medium turning, while the HU3 chipbreaker helps maintain consistent chip segments across variable cutting depths.

FAQ

What materials is this insert suited for?
The CNMM120408-HU3 WPP30G is designed for machining materials in the ISO P group, primarily unalloyed and alloyed steel, and the grade WPP30G balances wear resistance and toughness for these steels.

How does the HU3 chipbreaker affect machining performance?
The HU3 chipbreaker provides reliable chip segmentation and evacuation, improving process stability and reducing the risk of chip interference during turning operations with this Walter Tools insert.

What is the advantage of the 0° negative rake?
A 0° negative rake increases cutting edge strength and resistance to shock, making the insert suitable for heavier cuts and intermittent cutting conditions while maintaining dimensional consistency.
