P4840P-2R-E77 WNN15 Drill/Boring Indexable Insert (Walter Tools) – Coated carbide, 2R‑E77 chipbreaker
The P4840P-2R-E77 WNN15 is an indexable insert engineered for drilling and bore-enlargement tasks in industrial machining, offering stable chip control and consistent performance in series production.
- Coated carbide grade WNN15
- Chipbreaker 2R-E77 for stable chips
- Designed for drilling and bore finishing
Consistent process reliability through optimised grade and geometry
The combination of a coated carbide grade and a targeted chipbreaker geometry reduces interruptions and contributes to predictable results in repeated operations. The WNN15 grade is specified as a coated cemented carbide and, together with the 2R‑E77 chipformer, promotes stable chip formation, which lowers the risk of workpiece damage and improves cycle-time stability. For production planners and machining engineers, this means fewer process adjustments and more reproducible component quality.
Efficient chip control and machining productivity
An insert with a dedicated chip control solution supports higher material removal rates while maintaining surface finish requirements. The 2R‑E77 breaker is designed to guide chips away from the cutting zone during drilling and bore-enlargement operations, helping to avoid rework and machine stoppages. This geometry supports productive machining by enabling steady feed and speed combinations where the toolholder and machine rigidity match the operation demands.
Application guidance and compatibility considerations
Material suitability for this insert must be checked against the manufacturer product matrix; the WNN15 grade is described as a coated carbide and its effective range depends on the concrete matrix entry. The insert is presented as part of the Walter cutting-grade series and is catalog-dependent for exact material recommendations. Where uncertainty exists regarding alloy, hardness or process setup, a brief material and process description alongside machining parameters will allow technical advisors to confirm compatibility and optimise cutting data.
