P4840P-6R-E57 WKP25S — Drilling/reaming indexable insert by Walter Tools

A P4840P-6R-E57 WKP25S drilling and reaming indexable insert designed for efficient machining of steel and cast iron in general workshop and production environments.

• Tiger·tec Silver coating technology
• Optimised chipformer 6R‑E57
• Suited for steel (P) and cast iron (K)
• Coated carbide grade WKP25S

Boosted productivity through a high‑performance coating

The combination of Tiger·tec Silver surface technology and the WKP25S coated carbide grade provides a balance between wear resistance and toughness that supports longer tool life and consistent results in series production. The coating reduces flank wear and improves thermal stability, which translates into fewer index changes and more uptime on the machine. For operations sensitive to process reliability, this insert delivers predictable performance under continuous cutting conditions.

Controlled chip formation for safer drilling and reaming

An optimised 6R‑E57 chipformer ensures controlled chip breaking and evacuation when machining both unalloyed and alloyed steels as well as cast iron. The geometry focuses on producing short, manageable chips to reduce the risk of tool jams and improve surface finish. For customers with mixed material lots, the ability to maintain chip stability across steel and cast iron reduces set‑up complexity and increases throughput without sacrificing component quality.

Robustness and repeatability for production environments

Manufactured to Walter Tools’ quality standards, the insert offers a stable cutting edge and repeatable seating for indexed toolholders, supporting predictable tolerances and minimised rework. The coated carbide substrate provides resistance to abrasive wear from cast materials while retaining edge integrity in steel machining. This reliability contributes to lower production variability and supports cost efficiency over multiple tool life cycles.

Practical integration and application support

The insert integrates easily into standard indexable drilling and reaming toolholders that accept the P4840P‑style geometry. For process optimisation, Metav Werkzeuge can provide application advice—including recommended feeds, speeds and coolant strategies—based on specific workpiece material and machine capability. If further technical data is required, the supplier’s consultants are available to assist by e‑mail or phone.
