P2840S-6N-E77 WNN15 Drilling/Boring Indexable Insert — 6N-E77 chipformer, coated carbide (Walter Tools)

A P2840S-6N-E77 WNN15 indexable insert engineered for productive drilling and bore-enlargement tasks in industrial metalworking.

• Coated carbide grade WNN15
• 6N-E77 chipformer geometry
• Designed for drilling and boring
• Walter Tools quality and consistency

Improved process reliability for drilling and boring

The P2840S-6N-E77 WNN15 combines a coated carbide substrate with a dedicated 6N-E77 chipformer to provide stable cutting behaviour in many machining scenarios. The combination of a robust substrate and an optimised chip control design reduces the risk of irregular chip formation, which in turn supports longer tool life and fewer interruptions in production. This indexable solution is geared towards users who require repeatable results under industrial conditions; compatibility with specific workpiece materials should be verified against the manufacturer’s product matrix.

Controlled chip formation that enhances surface quality

A clearly defined chipformer profile improves evacuation and reduces heat concentration at the cutting edge. The 6N-E77 geometry moderates chip curl and fragment size during drilling and bore-enlargement, which helps to secure better surface finishes and lowers the likelihood of built-up edge. Reduced chip-related issues contribute to more predictable cycle times and less rework. For process planning, the insert’s design supports both conventional and high-feed drilling strategies where controlled swarf is essential for uninterrupted operation.

Durable coated grade for broader application potential

The WNN15 designation refers to a coated carbide grade tailored for a balance between wear resistance and edge toughness. As part of the Walter Schneidstoffsorte - Serie offen, this grade is intended to provide general-purpose performance across a range of materials; however, detailed suitability must be checked in the product matrix for each application. The coating increases resistance to adhesive and abrasive wear, which translates into reliable tool life and steady repeatability in serial production. Choosing an insert with a consistent material and coating system supports predictable production planning and quality control.

FAQ

What workpiece materials is the insert suitable for?
Material suitability depends on the specific application matrix; the WNN15 coated carbide grade offers general-purpose performance, but the product matrix should be consulted to confirm suitability for particular materials.

How does the 6N-E77 chipformer affect machining?
The 6N-E77 chipformer is designed to control chip shape and evacuation during drilling and bore-enlargement, improving surface finish and reducing interruptions due to poor chip control.

Is the insert compatible with standard indexable drill bodies?
The insert is an indexable cutting element intended for drilling and bore-enlargement tool systems; mechanical compatibility must be verified against the tool body specifications and mounting geometry.

What practical benefits does the WNN15 coating bring?
The WNN15 coating increases wear resistance while maintaining edge toughness, resulting in more consistent cutting performance and reduced frequency of insert changes.
