P4840C-2R-F57 WKP35S drilling/bore-enlargement indexable insert by Walter Tools — Tiger·tec Silver, for steel and cast iron

The P4840C-2R-F57 WKP35S is an indexable insert designed for drilling and bore-enlargement operations, optimised for machining steel and cast iron with stable cutting behaviour

• Tiger·tec Silver coating for extended tool life
• WKP35S grade for steel and cast iron machining
• 2R‑F57 chipbreaker for reliable chip control
• Precision designation P4840C‑2R‑F57 for consistent geometry

Higher productivity through optimised coating and grade

The combination of the Tiger·tec Silver coating and the WKP35S grade delivers measurable gains in wear resistance and process stability when machining steels and cast irons. The advanced coating reduces flank wear and helps maintain cutting-edge integrity over longer tool life, which translates into fewer index changes and less machine downtime. For operations where repeatability and predictable tool change intervals are essential, this insert supports a more economical cycle time and improved tool utilisation.

Predictable chip behaviour and surface quality

Equipped with the 2R‑F57 chipbreaker, the insert is engineered to produce short, controllable chips that improve evacuation and reduce the risk of built-up edge. Effective chip control minimises interruptions during through-hole and enlarging passes and contributes to a consistent surface finish on mating bores. For those less familiar with chipbreaker geometry: the designation describes the rake and groove form tailored to break and guide chips away from the cutting zone, reducing thermal concentration and preserving dimensional stability.

Practical selection and workshop guidance for better results

Selection of the correct insert grade and geometry is decisive for a productive process. The P4840C‑2R‑F57 design is suited to the machining conditions typical for unalloyed and alloyed steel (ISO group P) and abrasive cast iron (ISO group K), offering broad applicability across mixed-series production. Technical advice and practical feed/speed recommendations are available from Metav Werkzeuge to align insert choice with machine capability and workpiece requirements, ensuring efficient implementation without trial-and-error.

FAQ

What materials is this insert best suited for?
The P4840C-2R-F57 WKP35S insert from Walter Tools is intended primarily for steel (ISO group P) and cast iron (ISO group K) applications, reflecting the WKP35S grade’s balanced performance for both material groups.

How does the Tiger·tec Silver coating improve performance?
Tiger·tec Silver reduces adhesive and abrasive wear on the cutting edge of the P4840C-2R-F57 WKP35S, extending effective tool life and helping to maintain dimensional stability during extended runs.

What advantage does the 2R‑F57 chipbreaker provide?
The 2R‑F57 chipbreaker is designed to create short, manageable chips during drilling and bore enlargement, improving evacuation and reducing the likelihood of chip-related interruptions or damage to the workpiece.

Can this insert be used for mixed-series production?
Yes, the WKP35S grade and the insert geometry of the P4840C-2R-F57 are suitable for mixed-series production involving various steels and cast irons, delivering consistent results across different batches.

How is the insert identified in stock and on drawings?
Identification is via the ISO-style designation and SKU: P4840C-2R-F57 WKP35S (SKU P4840C-2R-F57-WKP35S-WALTER), which matches catalogue entries and technical drawings for straightforward ordering.
