P2840S-7N-E67 WKP35S – drill/reaming indexable insert with Tiger‑tec Silver coating by Walter Tools

A robust P2840S‑7N‑E67 WKP35S indexable insert engineered for productive drilling and reaming in steel and cast iron, combining a coated carbide grade with an optimised chipbreaker for reliable machining performance

• Tiger‑tec Silver coating for extended life
• WKP35S: high‑performance coated carbide grade
• 7N‑E67 chipbreaker for controlled chips
• Suited to steel (P) and cast iron (K)

Longer tool life through modern coating technology

The combination of Tiger‑tec Silver and the WKP35S grade delivers improved wear resistance and consistent edge stability under the thermal and mechanical loads typical of drilling and reaming operations. The advanced coating reduces flank and crater wear, which translates into fewer insert changes and higher machine uptime. For production environments, this means a measurable improvement in process security and predictable tool‑life cycles, enabling more efficient planning and reduced unplanned stoppages.

Stable chip control that reduces interruptions

The 7N‑E67 chipbreaker is specifically shaped to break and evacuate chips reliably during deep or interrupted drilling cycles. Controlled chip formation reduces the risk of recutting and tool damage, supporting continuous machining even with variable material batches. As an indexable insert, the component offers quick index changes, keeping setup times short and maintaining production throughput. The insert’s geometry supports clean chip flow and consistent hole quality, which benefits both cycle time and surface finish.

Broad application range for demanding materials

Designed for ISO groups P (steel) and K (cast iron), this indexable insert is suitable for a wide spectrum of unalloyed and alloyed steels as well as abrasive cast components. The coated carbide grade and chipbreaker pairing make it well suited to typical workshop and industrial drilling tasks where thermal stability and abrasive wear resistance are required. For users evaluating tooling options, the insert offers a balance between productivity and predictable performance across common ferrous materials.
