CNMM160612-HU3 WPP20G turning insert — Tiger‑tec Gold, for Stahl turning — Walter Tools

The CNMM160612-HU3 WPP20G is a negative Rhombic 80° insert designed for general turning of Stahl; its coated‑carbide grade and HU3 chipbreaker suit a wide range of medium to heavy turning tasks

• Tiger‑tec Gold coating for reliable wear resistance
• Rhombus 80° insert profile for versatile turning
• Corner radius 1.2 mm for controlled chip formation
• Negative 0° clearance for robust cutting conditions

Boosted productivity through consistent wear resistance

The coated‑carbide Tiger‑tec Gold grade WPP20G delivers a balance of wear life and toughness that reduces unplanned tool changes. The insert’s coating and substrate combination provide a stable cutting edge, which translates into fewer interruptions and a more predictable process window when machining Stahl. For production environments this means improved cycle‑time stability and a lower cost per component through longer effective tool life and consistent surface quality.

Predictable chip control and improved surface results

The HU3 chipbreaker combined with a corner radius 1.2 mm helps form shorter, manageable chips and supports steady contact conditions at the tool tip. This geometry is particularly useful when working with medium‑strength steels where controlled chip formation reduces risk of entanglement and supports safer, higher feed rates. As a result, the insert contributes to reliable surface finishes and easier post‑process handling, reducing secondary operations.

Robust geometry for demanding cutting conditions

A negative 0° clearance and the Rhombus 80° format provide mechanical strength at the cutting edge and improved resistance to impact and radial loads. The insert’s form supports interrupted cuts and heavier depth‑of‑cut scenarios where a positive geometry might chip prematurely. For workshop and manufacturing settings that require dependable, repeatable performance, this indexable solution offers the mechanical stability needed to maintain productivity under variable conditions.

Application guidance and material suitability

The grade is tailored for the ISO group P, meaning it is optimised for machining Stahl such as unalloyed and alloyed steels. The WPP20G composition emphasises a balance between wear resistance and toughness—classified within the series as generally universal with good wear properties—making it suitable for a range of turning tasks from finishing to medium roughing. Selection of feeds, speeds and cutting depth should follow process trials to match machine rigidity and workpiece characteristics for best results.

FAQ

What materials is this insert intended for?
The CNMM160612‑HU3 WPP20G insert is specified for ISO group P and is therefore intended primarily for machining Stahl, covering many unalloyed and alloyed steel grades.

How does the Tiger‑tec Gold coating benefit production runs?
The Tiger‑tec Gold coating on the WPP20G grade improves wear resistance and provides a stable cutting edge, which helps extend tool life and maintain consistent cycle times in production settings.

Is this insert suitable for interrupted cuts or heavy radial loads?
Yes, the negative 0° clearance and Rhombus 80° geometry give the insert mechanical strength and resistance to impact, making it appropriate for interrupted cuts and more demanding turning conditions.

What chip control can be expected with the HU3 chipbreaker?
The HU3 chipbreaker with a corner radius of 1.2 mm promotes shorter, controllable chips and steady cutting conditions, supporting improved surface quality and safer chip evacuation during operations.
