P2840S-3N-E67 WK40 – drilling/bore‑enlarging indexable insert with 3N‑E67 chipbreaker, Walter Tools

The P2840S-3N-E67 WK40 is an indexable insert designed for drilling and bore‑enlarging operations, featuring an uncoated carbide grade and a 3N‑E67 chipbreaker to promote stable chip formation and reliable machining.

• Uncoated carbide grade WK40
• 3N‑E67 chipbreaker for controlled chips
• Suitable for drilling and bore enlargement
• Manufactured to Walter Tools standards

Stable chip control for predictable holemaking

The combination of the 3N‑E67 chipbreaker and the geometry of this indexable insert delivers consistent chip segmentation, which reduces the risk of clogging and improves evacuation from the bore. For machining centres and production lines where repeatability matters, this results in fewer interrupted cycles and a smoother tool life profile. The insert’s design translates into a more repeatable process, lowering setup variance and contributing to higher overall equipment effectiveness.

Carbide grade and specification guidance for safe selection

The cutting grade is WK40, an uncoated carbide class supplied in an open series by the manufacturer. This grade offers a balance of toughness and wear resistance appropriate for a range of metal‑cutting demands; however, the exact material suitability should be checked against the product matrix before planning operations. For customers unfamiliar with grade matrices: compare workpiece material, required cutting speed and the expected feed to establish the correct application window for this type of insert.

Integration benefits and workshop handling

Using this insert in compatible toolholders supports efficient tool management and reduced downtime. The geometry and chipbreaker help to lower manual rework and secondary finishing in many drilling and bore‑enlarging tasks, while the uncoated surface simplifies inspection and regrinding decisions. For procurement and stocking, the clear designation and SKU aid traceability and reordering through Metav Werkzeuge, keeping supply chains short and predictable.
