CNMG250924-RP7 WPP20G Turning insert — Rhombic 80° geometry, for Stahl, Walter Tools

CNMG250924-RP7 WPP20G is a coated carbide turning insert designed for general-purpose turning of Stahl with a focus on stable chip formation and extended tool life

• Tiger·tec Gold coating for durability
• Optimised RP7 chipbreaker for stable chips
• Rhombic 80° insert geometry, 2.4 mm radius
• Designed for machining Stahl, negative 0° relief

Increased process stability through advanced coating and chip control

The combination of the Tiger·tec Gold coating and the WPP20G grade offers a measurable advantage in durability and wear resistance when machining Stahl. The coating reduces flank and crater wear under typical turning conditions, extending the service interval and improving economy per part. The RP7 chipbreaker is engineered to produce predictable, short chips on a wide range of workpiece grades, reducing bail-out times and helping to maintain uninterrupted production. For operators and CAM programmers, this means fewer interruptions and a lower risk of tool-related scrap.

Geometry and edge design deliver consistent surface quality

The Rhombic 80° shape combined with a 2.4 mm corner radius and 0° (negative) relief ensures secure clamping in standard toolholders and robust cutting edges for medium to heavy cuts. The corner radius provides a balance between edge strength and surface finish, so lighter finishing passes achieve good results while heavier roughing cuts remain stable. The geometry also supports reliable insert indexing and repeatable part dimensions, which improves process control on batch production and supports predictable cycle times.

Clear material suitability and practical benefits for workshop use

Assigned to material group P, the grade is tuned specifically for Stahl applications, accommodating typical heat generation and chip behaviour in this group. As a coated carbide insert, it combines toughness and wear resistance suited to a broad range of unalloyed and alloyed Stahl grades. The nominal plate designation supports straightforward ISO-based selection and tool management: the insert is easy to identify in assortments and to match with appropriate holders and cutting data tables. This clarity reduces setup time and simplifies tool inventory in production environments.

FAQ

Is this insert suitable for general turning of Stahl?
The CNMG250924-RP7 WPP20G insert from Walter Tools is designed for material group P and is suitable for a wide range of Stahl turning tasks thanks to the Tiger·tec Gold coating and RP7 chipbreaker.

What benefits does the Tiger·tec Gold coating provide?
Tiger·tec Gold on the WPP20G grade improves wear resistance and heat management during turning, which helps extend tool life and maintain consistent surface quality when machining Stahl.

How does the RP7 chipbreaker affect machining?
The RP7 chipbreaker produces controlled, short chips across typical cutting conditions, improving chip evacuation and process security for the Walter Tools insert.

Can the insert be used for both roughing and finishing?
Yes; the Rhombic 80° geometry and 2.4 mm corner radius offer a compromise between edge strength for roughing and the capability to achieve acceptable finishes during finishing passes on Stahl.

How is the insert identified for tool management?
Identification follows ISO designation CNMG250924-RP7 WPP20G and the SKU CNMG250924-RP7-WPP20G-WALTER, which simplifies matching to holders and cutting-data charts.
