P4840C-5R-F57 WKP35S — Drilling/boring indexable insert with Tiger·tec Silver coating by Walter Tools

P4840C-5R-F57 WKP35S is an indexable insert designed for drilling and boring applications, optimised for machining steel and cast iron with a 5R-F57 chipbreaker geometry.

• Tiger·tec Silver coating for wear resistance
• Suitable for ISO groups P and K
• Coated cemented carbide grade WKP35S
• Geometry 5R-F57 for reliable chip control

Increased process stability through consistent edge performance

The combination of Tiger·tec Silver coating and the WKP35S grade provides stable cutting edges and enhanced resistance to abrasive wear. This results in predictable flank wear rates and a lower frequency of tool changes, which supports continuous production runs. For manufacturing environments where repeatability and throughput are priorities, the insert’s balanced substrate and coating chemistry reduces thermal and mechanical deterioration, helping to maintain dimensional integrity over extended tool life.

Clear suitability for steel and cast-iron applications

Designed for ISO groups P (steel) and K (cast iron), the insert’s microstructure and surface finish are tuned to the different chip and wear behaviours of these materials. In steel machining the coated substrate helps to manage heat build-up and reduce built-up edge formation; in cast-iron turning and drilling it mitigates abrasive wear and promotes short, breakable chips. This targeted compatibility simplifies tool selection for mixed workshops and ensures reliable performance across common production tasks.

Optimised geometry for efficient chip control and higher feeds

The 5R-F57 chipbreaker geometry focuses on consistent chip formation and evacuation during medium-to-deep boremaking. Stable chip control enables safely increased feed rates without compromising surface quality, which directly reduces cycle times. By delivering controlled chip shapes and minimised recutting, the insert supports productivity gains while protecting the component surface finish — a rational investment for shops seeking measurable improvements in machining throughput.

Practical handling and integration for production tooling

Identified as P4840C-5R-F57 WKP35S, this insert integrates easily into standard drilling and boring tool bodies that accept the P4840C family geometry. Clear designation simplifies procurement and inventory management, while the coated grade reduces unscheduled maintenance. When combined with supplier guidance and planned stocking, the insert helps to streamline tool-change procedures and maintain a steady production flow in both jobbing and serial manufacturing settings.
