P4840C-3R-F57 WKP35S — Indexable drilling/boring insert, Tiger‑tec Silver, Walter Tools

The P4840C-3R-F57 WKP35S is a coated indexable insert engineered for drilling and boring tasks, optimised for machining steel and cast iron in demanding production environments

• Tiger‑tec Silver coated for extended life
• WKP35S coated carbide grade
• Optimised 3R‑F57 chipformer
• Suited to steel and cast iron machining

Higher throughput through durable coating and grade

The combination of the Tiger‑tec Silver coating and the WKP35S grade is designed to deliver extended tool life and consistent wear behaviour in serial production. As a coated carbide insert, it handles the thermal and mechanical loads typical of cutting steel and cast iron, which means fewer tool changes and more continuous spindle time. The improved wear resistance translates into predictable performance, helping to maintain component quality over longer production runs while lowering overall tool consumption.

Stable chip control for fewer interruptions

The 3R‑F57 chipbreaker is engineered to produce manageable chip forms during drilling and boring, reducing the risk of chip entanglement and improving evacuation from the hole. Reliable chip control prevents damage to the workpiece and tool, which supports steady cycle times and reduces the frequency of manual interventions. For operations where coolant flow and chip clearance are constraints, this optimised chipformer helps sustain process stability and repeatable hole quality.

Broad material capability reduces inventory complexity

This insert is specified for ISO groups P and K, making it suitable for a wide range of steel and cast iron applications. Using one reliable grade across multiple material groups reduces the need to stock many specialised inserts and simplifies tool planning. The material adaptability of the grade supports mixed-production environments where quick changeovers are required, contributing to higher machine availability and a more efficient tooling strategy.

Practical integration and application guidance

The insert geometry and coated grade are compatible with common indexable drilling and boring tool systems, enabling straightforward replacement and integration into existing toolholders. Alongside the technical advantages, application-focused guidance is available to match the insert geometry with machine capability and process parameters. This combination of a robust insert design and targeted technical advice helps to achieve consistent hole quality and operational efficiency in everyday production.
