CNMM120408-HU3 CNMM120408-HU3 WPP10G Turning Insert — Tiger‑tec Gold for Steel | Walter Tools

CNMM120408-HU3 WPP10G is a precision turning insert designed for robust steel machining, offering consistent chip formation and extended service life for series production.

• Tiger‑tec Gold coated for extended life
• Optimised HU3 chipbreaker for stable chips
• Rhombic 80° form with 0.8 mm corner radius
• Negative 0° rake for robust cutting

Higher process efficiency through optimised coating and grade

The combination of the Tiger‑tec Gold coating and the WPP10G carbide grade provides improved resistance to abrasive wear while maintaining toughness for interrupted cuts. This formulation is particularly beneficial in steel applications, as the coating supports stable chip control and reduces flank wear, which translates into longer tool life and fewer tool changes. The result is a measurable improvement in machine uptime and a lower cost per part in medium- to high-volume production.

Precise chip control and geometry for predictable results

The insert’s HU3 chipbreaker and rhombic 80° geometry deliver consistent chip formation under varying cutting conditions. The controlled chip flow reduces the likelihood of built-up edge and improves surface finish on turned components. With a 0.8 mm corner radius and a negative 0° rake, the design prioritises robustness and repeatability, making it well suited to roughing passes and stable finishing operations where repeatability is required.

Versatility for common steel applications

Manufactured for use on steels (material group P), the insert is tuned to the thermal and mechanical characteristics typical of unalloyed and alloyed steels. The grade balance between wear resistance and toughness enables reliable performance across a broad range of steel grades and cutting conditions. For shops seeking a single indexable solution for many turning tasks, this insert minimises tool inventory complexity while ensuring consistent performance.

Simple integration into standard tool holders and routines

The insert matches conventional CNMM clamping systems and is compatible with standard turning setups, allowing easy introduction into existing production processes. The reliable geometry and coating reduce the need for process fine-tuning, enabling faster ramp-up on new parts. For production engineers, this means predictable machining parameters and reduced setup time, supporting continuous, efficient manufacturing.

FAQ

Is this insert suitable for alloyed steels?
The CNMM120408-HU3 WPP10G insert is specified for material group P, so it is suitable for unalloyed and alloyed steels where the Tiger‑tec Gold coating and the WPP10G grade help manage heat and wear during turning.

Which chipbreaker should be chosen for mixed finishing and roughing?
The HU3 chipbreaker on this Walter Tools insert is optimised for stable chip formation across roughing and finishing ranges, providing predictable chips and improved surface quality on steel.

Can the insert tolerate interrupted cuts?
Yes, the WPP10G grade offers a balance of toughness and wear resistance that supports interrupted cutting in steel, while the negative rake and 0.8 mm corner radius enhance robustness.

How does the Tiger‑tec Gold coating affect tool life?
The Tiger‑tec Gold coating improves resistance to abrasive wear and helps maintain edge stability, which typically leads to longer service life and more consistent component quality when turning steel.

Is special clamping hardware required for this geometry?
No special clamping hardware is necessary; the insert conforms to standard CNMM holder interfaces and can be integrated into common turning tool setups.
