P4841C-7R-F57 WKP35S – Drilling/boring indexable insert, Tiger‑tec Silver coating (Walter Tools) for steel and cast iron

The P4841C-7R-F57 WKP35S is a robust indexable insert designed for drilling and boring operations, optimised for machining steel and cast iron in production environments where consistent chip formation and tool life are essential

• Tiger‑tec Silver coating for extended tool life
• WKP35S grade optimised for steel and cast iron
• Stable chip control and predictable performance
• Designed for drilling and boring indexable systems

Longer tool life through advanced coating and grade

The combination of the Tiger‑tec Silver coating with the WKP35S cutting grade delivers a significantly improved resistance to abrasive wear and thermal loading compared with conventional grades. This coated carbide chemistry reduces flank and crater wear during continuous drilling or boring cycles, which in turn extends tool life and reduces downtime for insert changes. For operations where thermal peaks and intermittent contact occur, the stable cutting edge behaviour contributes to fewer rework cycles and more predictable maintenance intervals, improving overall process reliability.

Predictable chip formation and application range

Designed for ISO material groups P (steel) and K (cast iron), the geometry and the 7R‑F57 chipbreaker support consistent chip breaking and evacuation during deep hole drilling and boring tasks. The insert’s chip control capability reduces the risk of damage to bores and cutting edges, enhancing surface finish quality and minimising secondary operations. For shops working across unalloyed, alloyed steels and a variety of cast iron grades, this cutting solution provides a balanced performance profile that supports productivity without requiring frequent parameter changes.

Practical benefits for workshop productivity

Integrating this grade into indexable drill or boring systems provides tangible process benefits: fewer insert changes, stable cycle times and improved throughput. The combination of coating technology and a geometry focused on chip guidance means reduced heat build‑up at the cutting zone and lower likelihood of built‑up edge formation. Process planners will find that the insert supports higher consistent machining performance, while operators appreciate the predictable behaviour during multi‑piece runs—factors that contribute to better machine utilisation and lower per‑part cost.

FAQ

What materials are suitable for this insert?
The insert is designed for ISO groups P (steel) and K (cast iron); the WKP35S grade and Tiger‑tec Silver coating specifically support machining of these workpiece families with stable chip control.

Can the insert be used for both drilling and boring operations?
Yes, the geometry and chipbreaker make the insert suitable for drilling and boring indexable systems, providing reliable chip evacuation and surface quality in both applications.

How does the Tiger‑tec Silver coating help in daily production?
The coating increases resistance to abrasive wear and thermal stress, which results in longer tool life and more consistent performance across production runs.
