P4841P-1R-A57 WKP25S — Drilling/boring indexable insert for steel and cast iron, Walter Tools

The P4841P-1R-A57 WKP25S is a coated carbide indexable insert from the Tiger·tec Silver series, engineered for efficient drilling and boring in steel and cast iron applications.

• Tiger·tec Silver coating for extended life
• Optimised for steel and cast iron machining
• Stable chip formation and consistent edge

Reliable performance in steel and cast iron machining

The insert combines the WKP25S grade with the Tiger·tec Silver coating to deliver consistently low wear rates when machining the ISO groups P (steel) and K (cast iron). The chemistry and coating architecture are tuned to the thermal and abrasive demands of these materials, so the component maintains edge stability under varying cutting conditions. For production environments this means fewer tool changes and reduced unplanned downtime, resulting in a measurable improvement to overall throughput.

Coating technology that extends service intervals

The coated carbide substrate, together with the Tiger·tec Silver top layer, improves resistance to adhesion and abrasive wear. This surface treatment supports a stable cutting edge and helps prevent premature flank wear during extended cycles. The practical benefit is longer intervals between regrinds or insert changes and more consistent surface finish on turned or bored features, which translates directly into lower unit costs and faster cycle times on batch and single-part production.

Geometry and chip control for secure machining

The 1R-A57 chipbreaker geometry is designed to produce short, manageable chips in a wide range of cutting conditions, promoting stable chip formation and safe evacuation from the hole. Stable chips reduce the risk of built-up edge and machine interruptions; the consequence is improved process reliability and repeatable hole quality. In workshops where predictable tool life and shop-floor efficiency are priorities, this insert contributes to fewer scrap parts and a smoother production flow. Technical drawings and cutting data can be provided to align insert selection with specific spindle speeds and feed rates.
