P4841P-6R-A57 WKP25S Drill/reaming indexable insert, Tiger‑tec Silver coating (Walter Tools)

The P4841P-6R-A57 WKP25S is an indexable insert engineered for drilling and reaming operations, optimised to deliver stable cutting performance in steel and cast iron applications.

• Tiger‑tec Silver coated carbide grade WKP25S
• Optimised for steel and cast iron machining
• Reliable chip control with 6R‑A57 geometry
• Compatible with standard indexable drill bodies

Increased throughput through advanced coating and geometry

The combination of the Tiger‑tec Silver coating and the WKP25S coated carbide grade provides improved resistance to abrasive and adhesive wear, which translates into longer tool life and fewer interruptions on the production floor. The 6R‑A57 chipformer has been developed for predictable chip formation in interrupted and continuous cutting, reducing the risk of built‑up edge and minimising recut. For production environments where cycle time and tool change frequency directly affect output, this insert supports a measurable increase in processed parts per shift while maintaining repeatable performance.

Consistent hole quality and repeatability in machining

Designed as a drill/reaming indexable insert, the geometry ensures dimensional stability and surface finish during holemaking cycles. The insert's geometry and edge preparation deliver consistent cutting forces that help to maintain tight tolerances across batches. This stability is particularly relevant when machining ISO groups P (steel) and K (cast iron), where chip behaviour and thermal loads differ; the cutting concept balances these factors to reduce variation in bore diameter and surface roughness. The P4841P‑6R‑A57 WKP25S therefore suits applications that require dependable accuracy without excessive process tuning.

Practical integration and clear application guidance

The insert is suitable for conventional indexable drillholders and reaming bodies that accept this WPL designation, enabling straightforward integration into existing toolsets. The material classification P / K indicates suitability for steel and cast iron according to ISO 513; this helps in tool selection and process planning by matching workpiece material to the optimised grade. Handling is standard for coated carbide inserts: ensure correct seating, torque specification for the clamping screw and appropriate coolant/lubrication strategy to exploit the coating’s potential. For special material mixes or atypical machining conditions, Metav Werkzeuge can advise on cutting data and holder compatibility.

FAQ

What materials is this insert designed for?
The P4841P‑6R‑A57 WKP25S insert is specified for ISO groups P (steel) and K (cast iron), reflecting the coated carbide grade's balance between toughness and wear resistance.

Which chipformer does the insert use and what is its benefit?
The insert features the 6R‑A57 chipformer, which promotes controlled chip breakage and reduces the likelihood of unstable chips in both continuous and interrupted cuts.

Is this insert compatible with existing indexable drill holders?
Compatibility depends on the holder specification, but the insert follows common WPL designation standards and is intended for use with standard indexable drill and reaming bodies that accept this form factor.

How does the Tiger‑tec Silver coating improve performance?
The Tiger‑tec Silver coating enhances wear resistance and thermal stability, extending tool life and supporting consistent cutting in demanding steel and cast iron operations.
