P2840S-4N-E67 WK40 — Drill/reaming indexable insert with 4N‑E67 chipbreaker by Walter Tools

The P2840S-4N-E67 WK40 is an indexable insert designed for drilling and reaming operations, offering controlled chip evacuation and stable cutting behaviour in productive machining environments

• Uncoated carbide, Walter WK40
• Chipbreaker 4N‑E67 for reliable chip control
• For drilling and reaming operations

Consistent performance with the WK40 carbide grade

The WK40 grade is supplied as an uncoated carbide designed for stable cutting when used within its specified application window. This material choice reduces the risk of unwanted adhesion and supports repeatable edge behaviour during medium-demand operations. For manufacturers seeking predictable tool life and consistent hole quality, the material composition contributes to fewer machining interruptions and more reliable process parameters, translating to increased uptime and lower scrap rates.

Controlled chip formation for safer, faster cycles

The 4N‑E67 chipbreaker geometry focuses on effective chip control, shaping chips to avoid entanglement and re-cutting. A well-designed chipbreaker reduces heat concentration at the cutting edge and improves evacuation from the tool zone, which helps to maintain surface finish and reduces the likelihood of tool failure. The result is a measurable improvement in cycle stability and a reduced need for unplanned tool changeovers during drilling and reaming tasks.

Practical guidance for selection and integration

As an indexable insert for drilling/reaming, the component is catalogue-dependent in terms of seat dimensions and compatible tool holders; check the product matrix to confirm fitment. The insert is supplied in the Walter Tools series open, which denotes an uncoated carbide offering; match the P2840S-4N-E67 WK40 to the intended feed and speed ranges and the specific workpiece material to achieve optimum results. For applications where the workpiece or operating conditions are atypical, an application review is recommended to ensure the chosen grade and chipbreaker deliver the intended productivity gains.
