CNMM120412-HU3 WPP30G — Turning indexable insert, Tiger‑tec Gold coating, for steel (Walter Tools)

The CNMM120412-HU3 WPP30G is a coated turning insert designed for robust steel machining, featuring a rhombic 80° form, a 1.2 mm corner radius and the HU3 chipbreaker for predictable chip formation

• Tiger‑tec Gold coating WPP30G
• 0° negative rake for robust cutting
• Rhombus 80° form, 1.2 mm corner radius
• Optimised for steel machining (ISO P)

Stable, repeatable performance that reduces process variation

The Tiger‑tec Gold grade WPP30G is a coated carbide specifically engineered for machining steel under the thermal and mechanical conditions typical of turning operations. Its combination of coating technology and substrate hardness yields improved edge life and consistent wear behaviour, which in turn supports predictable tool-change intervals and fewer unscheduled stops. For production environments where cycle time and reproducibility matter, the insert’s geometry and coating deliver measurable improvements in process stability and part quality.

Controlled chip formation and secure cutting geometry for safer cycles

The HU3 chipbreaker and the rhombic 80° insert form work together to direct chips reliably away from the cutting zone, reducing the risk of entanglement and surface damage. The 0° negative rake provides a more robust cutting edge for interrupted cuts and heavy cross‑sections, while the 1.2 mm corner radius balances edge strength with surface finish. These design choices make the insert suitable for a range of turning tasks on steels, from medium cuts to tougher operations where chip control and edge security are priorities.

Productivity gains through application focus and serviceability

By focusing on the ISO P workpiece group, the insert delivers an economical mix of wear resistance and toughness that supports longer tool life in many standard steel applications. The cartridge‑style indexable design allows rapid seat changes and consistent orientation, so setup disruptions are minimised and throughput is improved. For workshops aiming to raise output without sacrificing surface quality, the coated grade and geometry of this insert create a favourable cost‑per‑part profile and reliable repeatability in serial production.

FAQ

Which materials is this insert intended for?
The CNMM120412‑HU3 WPP30G insert from Walter Tools is optimised for steel (ISO P) machining and is formulated to handle the heat and chip characteristics typical of these materials.

What does the HU3 chipbreaker provide?
HU3 is designed for predictable chip control and effective chip evacuation, improving surface integrity and lowering the risk of chip re‑cutting during turning operations.

Is the Tiger‑tec Gold coating suitable for high‑feed or heavy cuts?
The Tiger‑tec Gold coating on the WPP30G grade enhances wear resistance and edge stability, making the insert well suited to demanding cuts on steel where edge robustness matters.

How does the 0° negative rake affect performance?
A 0° negative rake increases cutting edge strength and resistance to chipping, which is beneficial for interrupted cuts and tougher turning tasks while maintaining acceptable cutting forces.

What is the purpose of the 1.2 mm corner radius?
A 1.2 mm corner radius provides a compromise between edge strength and surface finish, offering longer life under load and a consistent surface on turned components.
