P4840P-3R-E57 WKP25S Drilling/Boring indexable insert – Tiger·tec Silver, for Steel and Cast Iron by Walter Tools

The P4840P-3R-E57 WKP25S is a drilling and boring indexable insert designed for medium- to high-productivity operations in steel and cast iron, combining a wear-resistant coating with a geometry optimised for stable chip formation.

• Tiger·tec Silver coating for enhanced wear resistance
• Coated carbide grade WKP25S for long tool life
• Designed for steel (P) and cast iron (K) machining
• 3R-E57 chipbreaker for controlled chip formation

Durable coating and grade for longer production runs

The combination of the Tiger·tec Silver coating and the WKP25S grade yields a coated carbide solution that reduces flank wear and maintains cutting-edge stability under cyclic loads. Coated carbide means a hard cemented-carbide substrate with a thin, engineered coating that reduces friction and heat impact at the cutting edge; this leads to longer tool life and fewer tool changes in serial production. For operations where consistency matters, the reduced wear rate translates directly into fewer stoppages and improved output per shift, supporting predictable machining cycles.

Stable chip control for safer, uninterrupted machining

The insert’s 3R‑E57 chipbreaker geometry is tailored to produce short, controllable chips when machining steel and cast iron. A chipbreaker shapes the chip as it forms, preventing long swarf and minimising the risk of entanglement or tool damage. The result is improved process reliability and a lower likelihood of manual interventions, which supports higher feed rates and better surface finishes. Clear chip control also contributes to safer operation in automated cells and multi-tool setups, where consistent chip morphology is crucial.

Application benefits and integration into production workflows

As a drilling and boring indexable insert, the component is intended for fast replacement and straightforward tool management in standard toolholders. Its suitability for material groups P (steel) and K (cast iron) – as indicated by the grade selection – enables focused tool inventory planning and efficient sorting by material family. The insert’s geometry and coating support predictable tool life, which helps calculate maintenance intervals and cost-per-part metrics. The combination of robust edge stability and engineered chipbreaker makes this insert a practical choice for workshops seeking repeatable results under varying batch sizes.

FAQ

Which materials is this insert suitable for?
The insert is specified for machining steel (P) and cast iron (K); the Tiger·tec Silver coating and WKP25S grade are matched to the thermal and abrasive conditions typical of these material groups.

What does the designation WKP25S mean?
WKP25S denotes Walter Tools’ coated-carbide grade within the Tiger·tec Silver family; it indicates a balance of wear resistance and toughness suitable for general-purpose steel and cast-iron machining.

How does the 3R‑E57 chipbreaker affect performance?
The 3R‑E57 geometry controls chip shape and breakage, reducing the risk of long swarf, improving surface quality and enabling more consistent automated or manual drilling and boring operations.

Is this insert recommended for stainless steel?
Stainless steel suitability is not specified for this grade; the insert’s primary applications are in steel and cast iron as indicated by the grade designation.

Can the insert be used in high-volume production?
Yes — the combination of Tiger·tec Silver coating and the WKP25S grade is aimed at supporting extended tool life and process stability, which are beneficial in high-volume machining environments.
