P2841S-3N-E57 WKP25S — Drilling/boring indexable insert, Tiger‑tec Silver, for steel and cast iron | Walter Tools

The P2841S-3N-E57 WKP25S is a Tiger‑tec Silver indexable insert engineered for high‑productivity drilling and boring applications in steel and cast iron.

• Tiger‑tec Silver coated carbide
• Optimised for steel and cast iron machining
• 3N‑E57 chipbreaker for controlled chips
• Designed for stable edge life and productivity

Greater throughput through advanced coating and grade

The combination of the Tiger‑tec Silver coating and the WKP25S grade results in a tool substrate and surface system that reduces flank wear and improves thermal resistance. For production environments this means fewer tool changes and more consistent component quality. The coated carbide composition provides a balance between toughness and wear resistance, making the insert well suited to the typical heat and chip formation encountered when machining steel and cast iron under continuous and interrupted cutting conditions.

Consistent chip formation and reduced downtime

The 3N‑E57 chipbreaker geometry is designed to produce predictable, manageable chips in both short‑breaking and semi‑continuous forms, helping to avoid chip entanglement in drilling and boring cycles. Predictable chip control reduces machine stoppages and manual intervention, which increases process reliability on CNC centres and in high‑mix workshops. Stable chip evacuation also supports consistent coolant flow and tool life, contributing to fewer unplanned stops.

Practical benefits for workshop and CNC use

As an indexable insert, this solution simplifies tool inventory and reduces regrinding needs; worn edges are indexed rather than replaced in their entirety. The insert’s characteristics support productive machining strategies, permitting higher feed rates where appropriate and enabling repeatable results from batch to batch. The design aims to combine ease of handling with measurable operational advantages such as improved component surface finish and predictable tool change intervals.

Clear material guidance and recommended use cases

The insert is specified for the ISO material groups P (steel) and K (cast iron), reflecting its suitability for unalloyed and alloyed steels as well as abrasive cast materials. In practical terms, this means the insert is appropriate for a broad range of drilling and boring tasks in general engineering and automotive production where mixed‑material machining is common. For best results, match cutting parameters to the workpiece material and machine rigidity; the insert’s WKP25S grade and chipbreaker geometry support versatile performance across varied job profiles.
