CNMG250924-RP5 WPP20G – Turning insert, for Steel, Walter Tools

The CNMG250924-RP5 WPP20G is a rhombic 80° turning insert designed for efficient steel machining, featuring Tiger·tec Gold coating and an RP5 chipbreaker for reliable chip control.

• Tiger·tec Gold coated carbide
• RP5 chipbreaker for controlled chips
• 80° rhombic shape for stable cuts
• 2.4 mm corner radius for robustness

Consistent performance for steel machining

The WPP20G grade, part of the Tiger·tec Gold series, has been developed for productive turning of steel (ISO P). Its coated carbide composition provides high wear resistance, which translates into longer tool life and fewer indexings during multi-shift production. The RP5 chipbreaker is optimised for medium-depth cuts and promotes predictable chip shapes, reducing manual chip handling and downtime. For process planners, this combination means improved tool economy and consistent component quality across batches.

Geometry that supports productivity and reliability

The 80° rhombic shape and 0° negative rake geometry deliver a balanced mix of strength and versatility. The rhombic form gives axial security for a wide range of cutting depths, while the negative rake increases edge robustness for interrupted cuts and harder turning conditions. The 2.4 mm corner radius increases resistance to edge chipping and contributes to stable surface finish when paired with correct feeds and speeds. In practical terms, this geometry allows the tool to be used for both finishing and light roughing with fewer insert changes.

Coating and materials: what the technology does for the part

The Tiger·tec Gold coating on this coated carbide grade reduces abrasive wear and improves thermal stability during elevated cutting temperatures. For operations on unalloyed or alloyed steel, the coating minimises flank wear and helps maintain dimensional accuracy over longer tool life. The WPP20G chemistry balances toughness and hardness—suitable for typical heat generation and chip formation encountered in steel turning. Understanding these material properties helps production engineers choose cutting parameters that extend tool life while ensuring repeatable part quality.

Practical application and process guidance

In a production setting, the insert is well suited to general turning cycles where reliability and repeatable results are priorities. Use the RP5 chipbreaker when seeking consistent, curled chips for safe evacuation in automated environments; switch to conservative feeds during initial process trials to verify part finish and machine dynamics. As the grade is optimised for steel, expect good performance across a broad range of steels used in everyday manufacturing. For integration into an existing cell, document the achieved cutting data and review tool life over several batches to establish an economical replacement interval.

FAQ

What materials is this insert suitable for?
The CNMG250924-RP5 WPP20G is designed primarily for steel (ISO P) applications; its WPP20G grade and Tiger·tec Gold coating suit the heat and chip formation typical of steel turning.

How does the RP5 chipbreaker affect machining?
The RP5 chipbreaker produces controlled chip shapes that simplify evacuation and reduce manual chip handling; combined with the coated grade, it contributes to stable cutting in serial production.

What does the 0° negative rake mean for cutting conditions?
A 0° negative rake provides a stronger cutting edge suited to interrupted cuts and tougher conditions; it increases edge stability compared with positive rake geometries.

Is this insert suitable for finishing operations?
Yes—with appropriate feeds and speeds the rhombic 80° geometry and 2.4 mm corner radius deliver acceptable surface finishes for many finishing tasks while offering robust edge life.

Can the CNMG250924-RP5 WPP20G be used on automated lathes?
The insert’s stable chip control and predictable performance under the Tiger·tec Gold system make it appropriate for automated turning cells where repeatability and tool life are important.
