P4840P-1R-E57 WKP35S Drilling/Boring Indexable Insert, Tiger‑tec Silver, for Steel & Cast Iron — Walter Tools

The P4840P-1R-E57 WKP35S is a coated carbide indexable insert designed for drilling and boring operations in steel and cast iron, delivering stable cutting performance under demanding production conditions.

• Tiger‑tec Silver coating for improved wear resistance
• Optimised for steel (P) and cast iron (K)
• Coated carbide grade WKP35S for stable cutting

Longer tool life through advanced coating technology

The combination of the Tiger‑tec Silver series and the WKP35S grade provides an optimised coating system on a coated carbide substrate that reduces abrasive wear and extends service intervals. This engineering reduces unscheduled tool changes and supports higher productivity in series production. Where thermal loads are typical—such as in the machining of unalloyed and alloyed steel—the coating helps to lower flank wear and maintain a consistent cutting edge, which translates into repeatable process results and fewer scrapped parts.

Predictable chip formation and process stability

Equipped with the 1R‑E57 chipbreaker, the insert promotes controlled chip formation and evacuation during drilling and boring cycles. Stable chip control minimises interruptions and improves surface integrity on the workpiece, enabling higher feeds or longer tool paths without compromising quality. For workshop planners and CNC programmers, that means more predictable cycle times and less need for manual intervention, supporting efficient throughput and predictable output.

Application-focused performance for P and K materials

Specified for material groups P (steel) and K (cast iron) according to ISO guidance, the geometry and material combination are tuned to the typical heat generation and chip characteristics of these groups. The grade is a coated cemented carbide type, designed to handle the abrasive nature of cast iron and the ductile chip behaviour of steels. This targeted design reduces tool-related variability in mixed-material production runs and supports consistent surface finish and dimensional stability in drilled and bored features.

Practical benefits for production environments

In production environments where repeatability matters, the insert’s coated carbide construction and dedicated chipbreaker deliver a balance between edge robustness and chip control, lowering the frequency of tool changeovers and supporting longer tool life. The consistent performance contributes to economic machining: fewer disruptions, stable component quality and an easier path to achieving cycle-time improvements on high-volume batches. Toolroom staff and procurement teams will recognise the advantage of a standardised insert grade across multiple components and set-ups.
