Increased process reliability through premium coating and grade

The combination of the Tiger‑tec Gold coating and the WPP30G carbide grade delivers measurable improvements in tool life and edge stability when machining Stahl. The multilayer coating reduces flank wear and enhances thermal resistance, which supports higher cutting speeds and longer uninterrupted cycles. For production environments where predictable performance matters, this grade provides a clear reduction in tool changes and downtime, contributing to lower unit costs and steadier throughput.

Geometry and chip control that protect the cutting edge

With a Rhombus 80° shape, a 1.2 mm corner radius and a 0° (negative) rake, the insert offers a balance between edge strength and form accuracy. The RP5 chipbreaker is tuned for stable chip formation on typical Stahl grades, reducing the risk of built-up edge and improving surface finish. These geometric choices mean fewer reworks and consistent dimensional results, particularly on medium to heavy turning tasks where edge robustness is essential.

Versatile application range for efficient production

Designed for the ISO P material group, the insert is suitable for a wide spectrum of Stahl workpieces — from wear-resistant to tougher variants — enabling a single grade to cover multiple shop demands. The WPP30G composition lends itself to applications where a compromise between wear resistance and toughness is required, allowing process engineers to standardise tooling across mixed production runs and so simplify inventory management while maintaining productivity.

Practical handling and integration into existing tool systems

The CNMG120412-RP5 format, with an inscribed size of 12 and a plate thickness class of 04, fits common toolholders for indexable turning inserts, making changeover straightforward. The tolerance class M supports repeatable clamping and positional accuracy, which aids in achieving consistent part quality batch after batch. Specifying this insert in the tool setup improves predictability in cycle planning and reduces setup time for series production.

FAQ

What materials is this insert designed for?
The CNMG120412-RP5 WPP30G insert is optimised for Stahl (ISO P) materials and is intended for a range of unalloyed and alloyed steel applications.

How does the Tiger‑tec Gold coating improve performance?
The Tiger‑tec Gold coating on the WPP30G grade increases thermal and wear resistance, which extends tool life and allows for higher cutting parameters with the CNMG120412-RP5 insert.

What advantages does the RP5 chipbreaker provide?
The RP5 chipbreaker ensures stable chip formation on Stahl, improves surface finish and protects the cutting edge from built‑up edge, enhancing process reliability with the Walter Tools insert.

Is the insert suitable for heavy interrupted cuts?
Thanks to the Rhombus 80° geometry and a 1.2 mm corner radius, the CNMG120412-RP5 WPP30G offers robust edge strength that is beneficial for interrupted and semi‑heavy turning operations.
