P4841P-5R-E57 WKP35S — Drilling/Boring indexable insert with Tiger‑tec Silver, 5R‑E57 — Walter Tools

The P4841P-5R-E57 WKP35S is an indexable insert designed for drilling and boring tasks, optimised for production use on steel and cast iron components.

• Tiger‑tec Silver coating for extended tool life
• WKP35S grade tailored to steel and cast iron
• 5R‑E57 chipbreaker for consistent chip control
• Indexable insert for drilling and boring operations

Longer tool life through advanced coating and substrate

The combination of Tiger‑tec Silver surface technology and a coated carbide substrate reduces flank and crater wear under typical drilling conditions. Such coating technology lowers friction and improves heat resistance, which translates into a measurable increase in service life and fewer tool changes during production. For operations where downtime is costly, the insert’s wear resistance supports a steadier production rhythm and predictable tool-change intervals.

Predictable chip formation and safer bore quality

With the chipbreaker 5R‑E57, the geometry is tuned to produce stable, controlled chips during both drilling and boring cycles. Controlled chip formation reduces the risk of chip clogging and re-cutting, which in turn improves surface finish and dimensional consistency of bores. This targeted chip control supports higher feed rates and safer machine operation, especially in automated or long-run applications.

Optimised for steel and cast iron according to ISO groups

The WKP35S grade is specified for ISO groups P (steel) and K (cast iron), meaning the substrate and coating are selected to handle the heat and the abrasive wear typical of these materials. For mixed production lines that switch between unalloyed or alloyed steel and grey or ductile cast iron, a single insert grade offering broad material compatibility reduces tooling complexity and inventory while maintaining machining stability.

Seamless integration into production tooling systems

The insert designation aligns with standard indexable systems, making the component straightforward to fit into existing drilling and boring toolholders. The geometry of the insert supports reliable seating and repeatable positioning, which preserves bore tolerances across insert changes. Backed by Walter Tools engineering, this insert is suitable for machinists seeking to combine process reliability with simplified tool logistics.
