CNMM120408-HU5 WPP10G — Tiger·tec Gold turning insert, rhombic 80° for Stahl

CNMM120408-HU5 WPP10G is a coated turning insert from Walter Tools, engineered for robust medium‑duty to finishing operations in Stahl machining.

• Tiger·tec Gold coating for enhanced wear resistance
• Optimised HU5 chipbreaker for reliable chip control
• Rhombic 80° shape for versatile turning operations
• 0.8 mm corner radius for stable, repeatable cuts

Consistent performance through advanced coating technology

The CNMM120408‑HU5 WPP10G combines Tiger·tec Gold surface engineering with a coated carbide substrate to extend tool life under the heat and mechanical loads typical of Stahl machining. The WPP10G grade is developed for a balanced mix of wear resistance and toughness, supporting longer tool life and fewer interruptions for insert changes. This results in improved process stability and predictable tool‑change intervals on the shop floor.

Geometry that stabilises cutting and chip flow

The rhombic 80° geometry and 0.8 mm corner radius create a stable cutting edge that helps deliver consistent surface finish and dimensional control. The negative 0° clearance geometry increases edge strength for interrupted cuts and heavier engagement, while the chipbreaker HU5 is tuned to produce short, manageable chips when cutting Stahl. Together, these features reduce the risk of edge chipping and simplify chip handling in automated and manual turning operations.

Productivity and manufacturability advantages

Designed for versatile turning tasks, the insert’s balance of wear resistance and toughness supports higher metal removal rates where process reliability matters. The coated grade and robust geometry lower the frequency of insert replacements, improving uptime and contributing to a more efficient production rhythm. Where cycle-time optimisation and consistent part quality are priorities, this insert helps harmonise process reliability with predictable tool life.

Practical compatibility and shop‑floor integration

With a nominal size of 12 and thickness "04", the insert fits standard CNMM toolholders that accept rhombic 80° indexable plates. Tolerance class M and execution M indicate consistent manufacturing accuracy, which supports repeatable clamping and predictable performance. The designation aligns with ISO P (Stahl) recommendations, making it straightforward to select cutting parameters based on common Stahl cutting data and the toolholder system in use.

FAQ

Is this insert suitable for machining stainless steel?
The CNMM120408‑HU5 WPP10G is specified for P (Stahl) materials; suitability for rostfreier Stahl is not indicated in the provided data and therefore cannot be assumed.

What advantages does Tiger·tec Gold offer?
Tiger·tec Gold provides a multi‑layer surface system on the coated carbide substrate that improves wear resistance and thermal stability, which in the CNMM120408‑HU5 WPP10G leads to longer edge life during Stahl turning.

What cutting behaviour can be expected from the HU5 chipbreaker?
The HU5 chipbreaker on this insert is optimised for controlled chip formation in Stahl, producing chips that are easier to manage and reducing the risk of entanglement during continuous turning operations.

Which operations and holders are compatible with this insert?
The rhombic 80° form and CNMM format suit a wide range of turning applications, from medium‑duty to finishing, and are compatible with standard toolholders designed for CNMM indexable inserts; ensure holder compatibility with the size "12" and thickness "04".

What are the key dimensions and identification details for ordering?
Key specs: size 12, corner radius 0.8 mm, rhombic 80°, relief angle 0° (negative), chipbreaker HU5; SKU CNMM120408‑HU5‑WPP10G‑WALTER identifies the Walter Tools insert and its WPP10G grade.
