P2840S-3N-E77 WN15 — drill/reaming indexable insert by Walter Tools

The P2840S-3N-E77 WN15 is a drill/reaming indexable insert intended for productive metalcutting tasks, offering the geometry and chip control suited to general drilling and counterboring in a broad range of workpiece materials.

• Walter uncoated carbide grade WN15
• Precision chipbreaker 3N‑E77
• Open series for broad applications
• Designed for productive drilling

Stable, efficient cutting through chipbreaker design

The prominent benefit of the insert lies in the 3N‑E77 chipbreaker, engineered to promote stable chip formation and evacuation under varying cutting conditions. This geometry reduces the risk of chip packing and supports a consistent cutting force, which in turn improves process reliability and tool life. By combining the chipbreaking geometry with an open-series design, the insert fosters predictable metal removal, making it suitable for integration into existing drill heads and tool assemblies where repeatable results are required.

Material grade and series for predictable wear behaviour

The uncoated WN15 grade is an open-series carbide composition intended for a wide application spectrum; this provides a balance between toughness and wear resistance. As an uncoated grade, WN15 performs reliably where coatings may not be required or where coolant and process parameters are chosen to optimise edge life. The open-series designation indicates that cutting data should be selected with reference to the specific product matrix — this ensures that the grade and geometry are matched to the workpiece material and the machining strategy for repeatable performance.

Practical integration and setup advantages

The insert's designation and form factor simplify stocking and changeover in workshops that use modular indexable systems. The clear ISO-style labelling supports quick identification: P2840S-3N‑E77 WN15. Because the material specification is catalogue-dependent, the selection process benefits from consulting the manufacturer matrix to confirm suitability for particular alloys or machining parameters. The insert design promotes straightforward seating in compatible holders and allows efficient rotation or replacement during scheduled maintenance, reducing machine downtime.

Process confidence and brand-backed performance

Walter Tools is known for tools that support high process security and stable cutting edges across diverse applications; this insert continues that tradition by offering robust geometry in a tried-and-tested format. The combination of grade and chip control leads to enhanced productivity in serial operations and helps achieve consistent surface quality and dimensional stability. For operations seeking dependable indexable solutions, the insert represents a pragmatic choice that emphasises repeatability and economical tool management.
