P4840P-2R-E67 WKP25S — indexable insert for drilling and boring, Tiger·tec Silver, for Steel and Cast iron (Walter Tools)

A P4840P-2R-E67 WKP25S indexable insert engineered for efficient drilling and boring operations in steel and cast iron, combining a coated carbide grade with a geometry tuned for controlled chip formation.

• Tiger·tec Silver coating for high process security
• WKP25S coated carbide grade for durable edge
• 2R‑E67 chipformer for controlled chip breaking
• Optimised for Steel and Cast iron machining

Reliable performance for drilling and boring applications

The Tiger·tec Silver coating together with the WKP25S grade delivers a balance of wear resistance and edge toughness that supports consistent cycle times in production environments. As a coated carbide cutting grade, the insert copes well with the heat and mechanical loads typical of turning and boring into Steel and Cast iron, helping to extend tool life and reduce unplanned stoppages. This results in a measurable improvement in throughput and fewer tool changes during serial machining.

Efficient chip control that reduces downtime

The included 2R‑E67 chipformer is designed to produce short, controllable chips under a wide range of cutting conditions, which lowers the risk of chip entanglement and improves swarf handling in automated setups. By promoting predictable chip behaviour, the geometry supports stable cutting forces and a more consistent surface finish. In practical terms, controlled chip breaking can shorten cycle times and decrease machine cleaning intervals, contributing to overall shop-floor productivity.

Broad material compatibility and economical productivity

Designed for the ISO material groups P (unalloyed and alloyed steels) and K (cast irons), this insert is suitable where a single grade must cover diverse workpieces. The Tiger·tec Silver technology widens the application window, enabling reliable machining across different steels and many cast iron types without frequent grade swaps. The result is a reduced tooling complexity and lower inventory pressure while maintaining repeatable performance and good surface quality in production.
