P2840S-1N-E77 WN15 – Drilling/boring indexable insert, uncoated carbide | Walter Tools

The P2840S-1N-E77 WN15 is an indexable drilling/boring insert designed for precision metalcutting operations where consistent chip formation and dependable tool behaviour are required.

• Open-series uncoated carbide grade WN15
• Chipbreaker 1N-E77 for controlled chip removal
• Fit for P2840S-1N-E77 insert geometry
• Walter Tools quality and process reliability

Consistent chip control for reliable production

The insert features the 1N-E77 chipbreaker, engineered to deliver controlled chip formation during drilling and reaming tasks. Controlled chips reduce the risk of interruptions and minimise the need for manual chip handling, which supports a more predictable machining process and fewer unplanned tool changes. The chip control design contributes to better surface finish and repeatable results across batches, helping to sustain throughput in a production environment.

Proven grade and series for broad workshop use

This product is supplied in the WN15 grade, an uncoated carbide from the Walter open series, offering a balance of wear resistance and toughness suitable for a variety of industrial tasks. The material specification is catalog-dependent, so compatibility with specific workpiece materials should be verified against the manufacturer’s application matrix. The grade’s uncoated nature can be advantageous where thermal or chemical sensitivity to coatings is a consideration and where predictable tool wear behaviour is preferred.

Designed for integration and process security

The geometry and designation align with established insert families for drilling and boring, enabling straightforward replacement and toolholder matching. Use of a standardised insert like this supports inventory rationalisation and simplifies reordering. Backed by Walter Tools engineering, the component aims to deliver consistent cutting performance and long tool life when used within the advised operating parameters, supporting higher machine utilisation and stable production outcomes.
