CNMM120416-HU3 WPP20G Turning insert, rhombic 80°, Tiger‑tec Gold – Walter Tools

The CNMM120416-HU3 WPP20G is a rhombic 80° turning insert engineered for steel machining, combining a Tiger‑tec Gold coated carbide grade with an HU3 chipbreaker for reliable production performance

• Tiger·tec Gold coating for long tool life
• Optimised chipbreaker HU3 for stable chips
• Rhombic 80° geometry, 1.6 mm corner radius
• For steel machining (ISO P) with 0° negative rake

Durable coating and material pairing for longer tool life

The Tiger·tec Gold coating applied to this indexable insert provides enhanced wear resistance and temperature stability during continuous turning of steels. The coated carbide grade WPP20G is optimised for the thermal and mechanical conditions typical of steel machining (ISO P), which reduces flank and crater wear and extends usable life. This results in fewer tool changes, less downtime and a steadier process window on medium- to high-volume turning operations. The combination of coating and substrate technology supports predictable regrinds and consistent dimensional control across batches.

Stable chip formation for safer, more efficient turning

The integrated HU3 chipbreaker is designed to produce short, controllable chips when turning steel, improving both surface quality and operator safety. By controlling chip flow and breakage, the insert reduces the risk of entanglement and machine interruptions, which in turn supports higher effective cutting speeds and feed rates. The insert’s rhombic 80° geometry and 1.6 mm corner radius create robust cutting edges that resist edge chipping, offering a balance between strength and edge definition for general-purpose to semi-finishing operations.

Geometry and angles that expand application flexibility

With a rhombic 80° form and a 0° negative rake, this turning insert suits a wide variety of turning tasks, from longitudinal turning to facing and light profiling, especially where stable engagement and predictable tool behaviour are required. The ISO designation for steel (P) confirms suitability across unalloyed and alloyed steels, delivering a practical solution where versatility and process security are priorities. The insert’s dimensions and thickness code allow integration into many standard CNMM toolholders, simplifying logistics and inventory management.

Economic and process benefits in production environments

Choosing a coated grade such as WPP20G within the Tiger·tec Gold series supports cost-effective machining through longer tool life and consistent component quality. Fewer interruptions for tool changes and less scrap due to more stable cutting conditions translate into a lower cost per part. The robust design and optimised chip control also ease setup and reduce cycle-time variability, contributing to reliable throughput in both jobbing and serial production contexts.

FAQ

What materials is this insert suitable for?
The Walter Tools CNMM120416-HU3 WPP20G is specified for steel (ISO P), covering unalloyed and alloyed steels where the Tiger·tec Gold grade offers wear resistance and thermal stability.

How does the HU3 chipbreaker influence machining?
The HU3 chipbreaker on the CNMM120416-HU3 WPP20G controls chip formation to produce shorter, manageable chips, improving surface finish and reducing interruptions during turning.

What does the 0° negative rake mean for cutting performance?
A 0° negative rake provides a neutral to robust cutting edge suitable for stable engagement and resistance to edge damage, beneficial in general turning operations with the WPP20G grade.

Can this insert be used for finishing passes?
Yes; the rhombic 80° geometry combined with a 1.6 mm corner radius makes the insert appropriate for light finishing and semi-finishing where rigidity and edge strength are required.

Is the CNMM120416-HU3 WPP20G compatible with standard CNMM toolholders?
The CNMM form factor and size code are intended for standard CNMM toolholders; verify holder compatibility with insert dimensions before use.
