P2840S-1N-E77 WNN15 — Drilling/Reaming Indexable Insert, Walter Tools (1N‑E77 chipbreaker, coated carbide)

A P2840S‑1N‑E77 WNN15 indexable insert designed for drilling and reaming operations, intended for use where stable chip formation and repeatable performance are required

• WNN15 coated carbide grade
• 1N‑E77 chipbreaker for chip control
• Designed for drilling and reaming
• Walter Tools open series for versatile use

Stable chip control for uninterrupted productivity

The combination of the 1N‑E77 chipbreaker and the coated cemented carbide grade delivers predictable chip formation under varying cutting conditions. That predictable behaviour reduces the risk of flute clogging and interruption, which benefits overall cycle times and machine utilisation. The targeted geometry of the chipbreaker promotes short, controllable chips in common interrupted-entry and pocketing scenarios, supporting higher availability of the machining process without overclaiming specific material limits.

Coated grade engineered for process reliability

The WNN15 grade is a coated carbide class developed for productive metal cutting; the coating and substrate pairing aim to extend tool life and maintain a stable cutting edge. For planning purposes, the grade should be assessed against the manufacturer’s product matrix to confirm suitability for the intended workpiece materials. Clear documentation of the grade helps maintenance of cutting data records and supports repeatable set-ups across production batches.

Practical integration and holder compatibility

Manufactured as an indexable plate for drilling and reaming applications, the insert is compatible with holders designed for this insert geometry. The standardised designation facilitates quick identification in tool databases and ordering systems, helping procurement and toolroom teams to maintain concise inventories. Where holder or fixture details are required, compatibility checks against the toolholder catalogue are recommended to ensure secure clamping and correct cutting orientation.

Selection guidance and planning support

Selection of the correct insert grade and chipbreaker influences process stability and workpiece surface quality more than occasional adjustments to feed or speed. The coated carbide nature of the grade favours operations where wear resistance and edge stability are priorities. For complex specifications or unusual alloys, consultation of the Walter Tools product documentation and the Metav Werkzeuge advisers is advised to align the insert choice with production goals and to document expected performance parameters.
