CNMM190616-HU7 WPP20G indexable turning insert for Steel — Tiger‑tec Gold (Walter Tools)

CNMM190616-HU7 WPP20G is a coated carbide indexable insert designed for demanding steel turning applications, offering a balance of wear resistance and versatility thanks to the Tiger‑tec Gold technology and HU7 chipbreaker.

• Tiger‑tec Gold coated carbide grade WPP20G
• Optimised for steel turning applications
• Rhombic 80° geometry for diverse facing and turning
• Corner radius 1.6 mm for edge robustness

Productivity through a wear‑resistant grade

The combination of the WPP20G grade and Tiger‑tec Gold coating delivers a measurable improvement in tool life under typical steel turning conditions. Coated carbide reduces flank wear and helps maintain a consistent cutting edge, which leads to fewer insert changes and higher machine uptime. This performance advantage translates directly into improved throughput and a better cost per component when machining unalloyed or alloyed steel.

Geometry that supports stable cutting and versatility

The rhombic 80° geometry with a 0° negative rake provides a robust edge suited to a wide range of turning operations, including light roughing and finishing passes. A corner radius of 1.6 mm increases edge strength and reduces the risk of chipping when encountering interruptions or variable feed conditions. These geometric choices promote dimensional consistency and reliable surface quality across batch production.

Controlled chips and improved surface finish

The HU7 chipbreaker is engineered to generate short, manageable chips when cutting steel, enhancing operator safety and process stability. Predictable chip formation reduces the likelihood of built-up edge and helps maintain a clean cutting zone, which supports improved surface finish and predictable tool wear rates. The insert’s design therefore contributes to fewer secondary operations and smoother downstream handling.

Ready for production‑oriented setups

With tolerance class M and an indexable format, the insert integrates easily into standard tool holders and turret systems. The indexable design allows quick orientation changes for multiple cutting edges, supporting continuous operation with minimal downtime. For specialised requirements or compatibility checks, Metav Werkzeuge can supply holder recommendations and machining parameters to match the production environment.

FAQ

What materials is this insert intended for?
The CNMM190616-HU7 WPP20G insert is formulated primarily for machining steel (ISO group P), with the WPP20G grade optimised for typical steel heat and chip formation.

How does the Tiger‑tec Gold coating benefit production?
Tiger‑tec Gold enhances the coated carbide’s wear resistance and thermal stability, allowing the insert to deliver longer tool life and more consistent results under continuous cutting conditions.

What does the HU7 chipbreaker provide in practice?
The HU7 chipbreaker produces short, controlled chips during steel turning, improving chip evacuation and contributing to a more stable cutting process and better surface quality.

Is the insert suitable for finishing passes?
Yes; the rhombic 80° geometry and the 1.6 mm corner radius make the insert appropriate for both light roughing and finishing operations when correct feeds and speeds are applied.

How does tolerance class M affect use?
Tolerance class M indicates a standard machining tolerance suited to general production; it supports repeatable positioning in common toolholders for reliable dimensional accuracy.
